In this issue, we share information on pressure-sensitive adhesives in packaging applications, stabilizers, bonding untreated polypropylene, monitoring flow characteristics, and more!
Silicone-based coatings are among the most versatile materials used in a variety of industrial applications, including pressure-sensitive tapes, protective coatings, and the protection of printed text on packaging.
Epoxy silanes like GLYMO and GLYEO are adhesion promoters used in food packaging, but safety issues have prompted the development of new alternatives.

Consumers expect the food industry to provide safe products that comply with the latest regulations. FEICA, the Association of the European Adhesive and Sealant Industry, recommends avoiding the use of epoxy silanes in food contact applications, and the European Union is expected to set new limits during the course of this year. These limits will require complex testing methods that lead to challenges for converters and packaging manufacturers.
Raw materials in adhesives and sealants formulations are often protected from degradation by suitable stabilizer packages or through appropriate packaging.
Stabilizing additives such as antioxidants (AOs), ultraviolet (UV) absorbers, and hindered amine light stabilizers enable formulators to create durable adhesives and sealants, thereby extending the life of adhesively bonded goods.
The correct adjustment of flow characteristics of sealants and thermosetting adhesives is crucial to their performance in automated, high-speed production environments.
The automated application of sealants and adhesives in settings such as automotive production requires that predictable, reproducible quantities are applied, and that they flow properly and remain in place during the final setting period.
Adhesives incorporating polyurethane resin have been widely used in industry due to many desirable characteristics, such as a high adhesive property, chemical resistance, and flexibility.
Adhesive manufacturers are developing new technologies that converters can present to their packaged goods customers and enable them to capture more market share.
Pressure-sensitive adhesives (PSAs) continue to gain traction in the broad category of packaging. PSAs are rapidly changing the way goods are packaged and delivered to consumers in traditional retail and via ecommerce.
I profoundly hope that you are reading this issue of ASI in good health and from the safety of your own home. The last few weeks have seen an unprecedented global response to the threat of COVID-19—from school, restaurant, and facility closings to innumerable event postponements and cancellations.
You need to look at so-called “shadow curing” options. Most UV-cured systems are based on acrylates and methacrylates and cure free-radically by the decomposition of a photoinitiator.
Scouting for collaboration opportunities outside your company is a process that begins with defining and prioritizing the market's needs in a way that anyone unfamiliar with your business can understand.
Meeting the technical and product needs of customers can be very challenging, especially if R&D resources are constrained or you do not have the right in-house expertise to deliver a timely response.
