Welcome to the 2021 ASI Top 20! Every year, we explore the leading worldwide manufacturers of adhesives and sealants to compile this list. In considering the rankings, we focus on sales figures (and other details) for finished adhesives and sealants, as well as related products such as tapes.

A very special thanks goes to those companies that responded to our requests and provided specific details regarding their adhesives and sealants operations and financial results. We appreciate your effort in compiling this information, as well as your trust in us, in some cases, to safeguard it. Your input immeasurably improves the quality of the list and helps ensure that it continues to be seen and used as a global industry resource.

In addition to information supplied by company contacts, we gathered details from annual reports, company websites, press releases, and other sources. In cases where organizations did not respond to our requests or declined to provide adhesives/sealants-focused information, and reasonable estimates could not be made based on publicly available information, some companies did unfortunately have to be left out.

If you would like your company to be considered for the 2022 ASI Top 20, or if you have any questions or suggestions for future rankings, please contact Susan Sutton, editor-in-chief, at (248) 786-1704 or suttons@bnpmedia.com.

1. Henkel AG & Co. KGaA

Düsseldorf, Germany


CEO: Carsten Knobel

Adhesive Technologies Board Member: Jan-Dirk Auris

Lower demand resulting from closures and other restrictions related to the global COVID-19 pandemic led sales to decline overall for Henkel in 2020. Though sales in the Adhesive Technologies business unit were down by 8.2% for the year, to almost €8.7 billion (approximately $10.6 billion), a company source reports that “the second half of the year saw a recovery in demand across all business segments and regions.”

The Adhesive Technologies segment represented 45% of Henkel’s overall sales in 2020. The company also operates segments for Beauty Care (19% of 2020 sales) and Laundry & Home Care (35%). Compared to 2019, Adhesive Technologies’ share of total sales declined (47% in the prior year), while Laundry & Home Care increased (33% in the prior year).

Four business areas comprise the Adhesive Technologies business unit: Automotive & Metals (22% of the segment’s sales in 2020); Packaging & Consumer Goods (33%); Electronics & Industrials (15%); and Craftsmen, Construction & Professional (30%). While the Packaging & Consumer Goods segment achieved positive organic sales for the year, due mainly to increased demand from the packaging sector, the other three business segments all saw organic sales decline for the year.

“In the first quarter of 2021, sales in the Adhesive Technologies business unit increased nominally by 6.7% percent from €2.2 billion [~ $2.7 billion] in the prior-year quarter to almost €2.4 billion [~ $2.9 billion],” the company source says. “Organically (i.e., adjusted for foreign exchange and acquisitions/divestments), sales increased by 13%. Performance in the first quarter was driven by significant ongoing recovery in industrial production.

“There is still great uncertainty as to how the pandemic will develop and how consumption and industrial output will be impacted. Based on the Q1 results, Henkel revised its guidance for 2021. For the Adhesive Technologies business unit, the performance of which is, to a large extent, dependent on the recovery in industrial demand, Henkel expects organic sales growth to range between 7-9% (previous guidance, 2-6%).”

Despite various pandemic-related challenges and lower demand, Henkel increased its spending on adhesives/sealants-related R&D in 2020 by about 2.5%, to €291 million (~ $355.1 million). Adhesive Technologies represented 58% of Henkel’s total R&D spending for the year.

“In 2021, the Adhesive Technologies business unit aims to continue to align its innovation activities and resources to technology development and expand its partnerships with companies engaging with the three megatrends of mobility, connectivity, and sustainability,” says the company source. “Especially sustainability will remain a key driver of innovation in all markets Henkel serves. With the opening of its new global Innovation Center in Düsseldorf during the course of 2021, the company will further strengthen its R&D capabilities.”

In 2020, Henkel employed (on average) 52,600 people globally; the Adhesive Technologies segment represented 47% of this total workforce. Adhesive Technologies operated 133 production sites in 2020.

2. 3M

St. Paul, Minn.


Chairman and CEO: Mike Roman

3M produces adhesives and sealants, as well as related products such as tapes and films, through its four main business segments: Safety and Industrial, Transportation and Electronics, Health Care, and Consumer. The company employs nearly 95,000 people worldwide.

3M reported that 2020 sales for the Industrial Adhesives & Tapes business within the Safety and Industrial segment was $2.6 billion, accounting for 22% of the segment’s total of about $11.8 billion. This represents a decline of about 5% compared to 2019.

The Stationary & Office business within 3M’s Consumer segment achieved sales of about $1.2 billion in 2020 (23% of the segment’s total of $5.3 billion). This business produces tapes and other office-related adhesive products.

3M invested $1.9 billion in R&D in 2020. In September, the company announced that a Sustainability Value Commitment would be required as part of all of its new product commercialization efforts. “Sustainability has always been at the core of 3M—but we’re looking to do more,” said John Banovetz, chief technology officer. “We are proud to formalize our commitment to this next step in innovating for a sustainable future.”

3. Avery Dennison Corp.

Glendale, Calif.


President, CEO, and Chairman of the Board: Mitch Butier

Avery Dennison’s total 2020 net sales were down by 1.4% compared to the prior year, due mainly to the COVID-19 pandemic, reaching almost $7 billion. (The company declined to provide specific adhesives/sealants-related sales and other details.)

Avery Dennison operates in three business groups: Label and Graphic Materials (LGM), Retail Branding and Information Solutions (RBIS), and Industrial and Healthcare Materials (IHM). LGM, which produces pressure-sensitive labels and graphics, saw sales dip about 1% in 2020, to almost $4.8 billion. IHM, which produces tapes, adhesives, and other fasteners, experienced a steeper decline of 7% due primarily to COVID-19 impacts on the automotive market. The segment achieved net sales of $631.9 million.

The company’s 32,000 employees work in over 50 countries. Total R&D spending increased by almost 22% in 2020, to reach $112.8 million.

4. H.B. Fuller

St. Paul, Minn.


CEO: Jim Owens

H.B. Fuller employs over 6,000 people worldwide. The company’s net revenue for its 2020 fiscal year (ended November 28, 2020) declined by 3.7% to nearly $2.8 billion, due primarily to various impacts of the COVID-19 pandemic. Organic revenue dipped 1.6% compared to the prior fiscal year.

H.B. Fuller operates in three main business segments: Hygiene, Health and Consumable Adhesives (representing 48% of 2020 total net revenue); Engineering Adhesives (39%); and Construction Adhesives (13%). Net revenue for Hygiene, Health and Consumable Adhesives, which produces adhesives for sectors such as packaging, medical, and hygiene, was essentially flat in the 2020 fiscal year at about $1.3 billion.

The Engineering Adhesives segment serves customers in industries such as transportation, electronics, and energy; 2020 net revenue declined by 6.1% to about $1.1 billion. Net revenue for Construction Adhesives also declined in fiscal 2020, by 6.9% to about $369 million.

“The diversity of H.B. Fuller’s products and customer set enabled us to mitigate the effects of COVID-19 on our business, and historically have supported resiliency in margins and cash flow during economic downturns,” says a company source. “For example, while automotive and commercial construction markets were suppressed in 2020, we saw an increase in demand for our paper tissue and towel, packaging and hygiene products.”

Along those lines, the company is cautiously optimistic for 2021. “Growth in some end markets, such as commercial construction and aerospace, will improve at a slower pace and may not yet return to 2019 levels of activity,” the source says. “Elevated demand for hygiene and health products, packaging, paper, and tissues and towels will likely continue into 2021 as consumers continue to spend more time in their homes.

“We anticipate Construction Adhesives’ end markets to continue to show steady improvement throughout 2021 with commercial activity improving throughout the year and residential activity remaining solid. Engineering Adhesives’ end market demand will likely remain at elevated levels in early 2021, reflecting increased production activity to meet some pent-up demand, returning to more typical activity levels in the second half of the year.”

H.B. Fuller invested in growth in Asia and South America in 2020, with an expansion of its site in Yantai, China (supports the electronics and energy industries), and the launch of a new global center of excellence in Rionegro, Colombia (for hygiene adhesives). In addition, the company has additional plans for new facilities in China and Egypt.

5. Arkema Group

Colombes, France


Chairman and CEO: Thierry Le Hénaff

Arkema operates in four business segments: Adhesive Solutions, Advanced Materials, Coating Solutions, and Intermediates. Bostik, which is Arkema’s Adhesive Solutions segment, represented 25.5% of group sales in 2020 (a slight increase over 2019’s 24%). As a result of COVID-19, Bostik saw sales decline by 2.9% for the year, to almost €2 billion (~ $2.4 billion).

The segment reported growth of 2.7% in the 2020 fourth quarter, however, with opportunities realized in construction and engineering adhesives. Bostik’s sales in the 2021 first quarter accelerated this growth rate to reach €555 million (~ $677.2 million).

“In first quarter 2021, sales for the Adhesive Solutions segment were up 7.8% compared to first quarter 2020, primarily driven by the rise in volumes,” says a company source. “Momentum remained strong in the construction and DIY markets, and the segment also benefited from the recovery of industrial markets in high-performance adhesives.”

In the fall of 2020, Arkema announced that it had inaugurated a new adhesive facility in Japan intended to enable Bostik to serve its Japanese customers in the diapers, hygiene, packaging, labelling, transportation, and electronics markets. In addition, the group clearly intends to grow the Adhesive Solutions segment through acquisitions, with 2020 buys including LIP Bygningsartikler AS, Fixatti, and Ideal Work. To date in 2021, Bostik has invested in Crackless Monomer Co., acquired Poliplas, and announced that it plans to acquire Edge Adhesives Texas.

6. Sika AG

Baar, Switzerland


CEO: Thomas Hasler

Sika employs nearly 25,000 people worldwide and achieved 2020 total net sales of almost CHF 7.9 billion (~ $8.8 billion). This represents a 3% decline compared to the prior year, primarily due to the impact of the COVID-19 pandemic. The company invested CHF 193.6 million (~ $215.6 million) in R&D in 2020, a decrease of 4% from 2019.

Sika did not respond to requests for specific adhesives/sealants details, but it cites adhesive systems as one of its five core technologies (along with concrete technology, coating systems, cementitious systems, and thermoplastic systems). The company’s total 2020 net sales of products for the construction industry were fairly flat at about CHF 6.4 billion (~ $7.2 billion), representing 81.7% of total sales for the year. The remainder of 2020 sales (18.3%) were for the industrial manufacturing sector; here, sales declined by almost 13% to around CHF 1.4 billion (~ $1.6 billion).

Sika’s target markets include: Concrete, Waterproofing, Roofing, Building Finishing, Flooring, Sealing & Bonding, Refurbishment, and Industry. The group produces adhesives and sealants, as well as related products, for almost all of these markets. Products range from roofing adhesives and tapes for waterproofing systems to structural adhesives and various offerings for building envelope applications.

7. RPM International Inc.

Medina, Ohio


Chairman and CEO: Frank C. Sullivan

RPM operates in four business segments: Construction Products Group (representing 34% of fiscal 2020 net sales), Consumer Group (35%), Performance Coatings Group (20%), and Specialty Products Group (11%). Total sales dipped by 1% for the 2020 fiscal year (ended May 31, 2020), to $5.5 billion. Organic sales declined by 0.8%, while acquisitions added 1.1% and foreign currency translation reduced sales by 1.3%. Regionally, RPM operates predominantly in North America (representing 75% of fiscal 2020 net sales), followed by Europe (17%), South America (4%), Asia-Pacific (3%), and Africa/Middle East (1%).

The company did not provide specific adhesives/sealants details. Each business segment produces numerous product ranges, with adhesives and sealants found mainly in the Construction Products Group and the Consumer Group. According to RPM, its DAP business leads in brand recognition and market share in the U.S. and Canada for the caulk and sealant residential market, as well as in the U.S. for wall and wood repair products.

In 2020, RPM aligned several divisions to create Tremco Construction Products Group (Tremco CPG). The impacted operating units included Tremco’s Commercial Sealants & Waterproofing, Roofing & Building Maintenance, and Barrier Solutions, as well as Dryvit, Nudura Inc., Willseal (Schul International Co., LLC), and Weatherproofing Technologies.

8. LINTEC Corp.

Tokyo, Japan


President and CEO: Makoto Hattori

LINTEC reported a 2% decline in net sales for its 2021 fiscal year (ended March 31, 2021), due primarily to the global pandemic, though demand for its products in semiconductors and electronics was consistently robust. The group employs over 4,900 people worldwide. Investment in R&D declined slightly in the 2021 fiscal year.

LINTEC operates in three business segments: Printing and Industrial Materials Products (adhesives for seals and labels, automotive adhesives, industrial adhesive tapes, films for various end uses, and other products); Electronic and Optical Products (semiconductor- and multilayer ceramic capacitor-related tapes, optical display tapes, and other products); and Paper and Converted Products. Mactac is part of the Printing and Industrial Materials Products segment (listed separately*).

(*Editor’s note: Since Mactac, LINTEC’s U.S. subsidiary, provided adhesives/sealants-related details and requested that they be withheld, specific sales levels for LINTEC will likewise not be published to avoid any conclusions potentially being drawn. Mactac’s sales were subtracted when determining LINTEC’s ranking.)

9. Illinois Tool Works Inc.

Glenview, Ill.


Chairman and CEO: E. Scott Santi

ITW is organized into seven business segments, two of which produce adhesives and related products. The company did not respond to requests for adhesives/sealants details.

With 2020 operating revenue of $2 billion (representing 15.9% of ITW’s total 2020 revenues), the Test & Measurement Electronics segment manufactures pressure-sensitive adhesives for electronics, medical, transportation, and telecommunications markets (among many other products). Revenue declined about 7.4% for the segment during the year, though the pressure-sensitive adhesives businesses saw a bit of an increase in North America.

10. Huntsman Corp.

The Woodlands, Texas


Chairman, President and CEO: Peter R. Huntsman

Huntsman’s Advanced Materials division “provides specialty epoxy, acrylic and polyurethane-based polymer resin systems and adhesive products.” According to Simon Thering, business development leader Adhesives, the company’s 2020 revenue for adhesives/sealants and related products was $840 million.

The Advanced Materials division represented 14% of Huntsman’s overall 2020 sales of $6 billion. The company attributed the division’s 20% drop in revenue for the year to reduced sales volumes in all of its markets, mainly as a result of the COVID-19 pandemic.

In November 2020, Huntsman announced that it had sold its India-based DIY consumer adhesives business to Pidilite Industries Ltd. The all-cash transaction was valued at up to $285 million.

14. Pidilite Industries Ltd.

Mumbai, India


Chairman: Madhukar Parekh

15. Nan Pao Resins Chemical Co., Ltd.

Tainan City, Taiwan


CEO: Elic Hsu

Nan Pao produces footwear adhesives, as well as other specialty and hot-melt adhesives, among other products. According to Roy Cheng, manager of the U.S. division, revenue for adhesives, sealants, and related products topped $401 million in 2020.

“Compared to 2019, the COVID-19 pandemic resulted in a distortion of normal revenue patterns in the first half of 2020,” he says. “By the 2020 second quarter, the gradual reopening of economies and consumer buying via sportswear ecommerce channels drove sales to rebound. Strong sales of hot-melt glue for hygiene and construction, and tape and label adhesives supported top-line performance. Overall, revenue on adhesives/sealants fell 11% YoY.”

Nan Pao is projecting adhesives/sealants sales growth for 2021, with opportunities in nonwovens, tapes and labels, flexible packaging, textiles, and woodworking. “We are shifting towards fewer product types and longer, high-volume production runs to achieve higher sustainable gross margins,” says Cheng.

The company employs over 2,900 people and operates factories and subsidiaries in Taiwan, China, Vietnam, Indonesia, Thailand, Malaysia, India, the Philippines, Singapore, and Australia. Sales in 2020 by plant location were from: mainland China, 35%; Taiwan, 20%; Vietnam, 24%; Australia, 13%, and Southeast Asia (except Vietnam), 8%.

Nan Pao invested $17.9 million on adhesives/sealants R&D in 2020, a 12% increase compared to 2019. “We will hold fast to innovation, systematically searching to apply existing core technology to new product opportunities,” Cheng says. “Thus, we expect adhesives/sealants R&D spending of sales for 2021 are likely to be similar to 2020.”

They are benchmarked in a thorough, multi-stage process, after which the winners are selected by a jury of representatives from business, science, and the media.

“We are extremely honoured to be recognised again as a Best Managed Company,” said Ralf Nitschke, Jowat SE managing director. “The award also assures us that our strategic approach, guided by sustainability with our employees and business partners is the right path into the future.”

19. DELO Industrial Adhesives

Windach, Germany


Managing Board: Wolf-Dietrich Herold, Ph.D.; Sabine Herold; Robert Saller

DELO achieved a revenue increase in its 2021 fiscal year (ended March 31, 2021). “Despite the global Covid-19 pandemic and its resulting major fluctuations in demand, DELO recorded revenues of €167 million [~ $203.9 million], a growth of 2% over the previous year’s €163 million [~ $199 million],” says Matthias Stollberg, head of Corporate Communications. “Particularly strong, double-digit revenue growth was recorded in Japan and South Korea.

Regionally, about half of DELO’s revenues were earned in Europe and North America in its fiscal 2021 year, with the remaining portion coming from Asia. China alone accounted for 35% of DELO’s revenues, while Germany represented 19%. The company’s key industry segments included: consumer electronics, 30%; automotive, 25%; and semiconductor, 20%.

DELO maintained its R&D spending throughout calendar year 2020, at about 15% of its annual revenues. Stollberg expects this spending level to continue through 2021.

In 2020, DELO focused particularly on high-tech adhesives that, in fact, are multi-functional polymer materials with additional properties,” Stollberg says. “Examples include liquid pressure-sensitive adhesives, adhesives as balancing compounds, and light-curing adhesives for liquid additive manufacturing.

DELO currently employs 820 people. During its 2021 fiscal year, DELO commissioned a new production hall with an area of about 8,000 m2 and several production lines. In addition, the company founded a subsidiary in Malaysia to reinforce existing activities.
