Adhesives & Sealants Industry Top Stories

RSS

Hybrid sealants are best defined as a fusion of technologies: the best performance properties of urethanes combined with the best of silicones.

When manufacturers are looking to use adhesives in an assembly operation, three steps must enter into the decision process: suitability, compatibility, and capability.

Hydrogenated styrenic block copolymers (HSBCs) are suitable for elastomeric adhesive applications. They are used in hot-melt adhesives (HMAs) and solvent-based adhesives, as well as in plastics modification for consumer and industrial applications

UV LEDs with peak spectral outputs of 365, 385, 395, or 405 nanometers (nm) are increasingly being used to cure adhesives formulated to work with LEDs. The impact of spectral differences should be evaluated based on the adhesive, photoinitiator package, and desired cure properties.

A recent study finds that naphthenic oils can offer a viable alternative to silicones in construction sealants. A newly developed range of specialty oils also provides formulators with the right balance between viscosity, color stability, and volatility.

The adhesive and sealant industry will come together for the first time in two years when the Adhesive and Sealant Council (ASC) holds its Convention & EXPO, scheduled for October 25-27 at the Omni Orlando Resort at ChampionsGate near Orlando, Fla.

Sika is sponsoring the Peak Evolution expedition, a challenging project to reach a new world record. The Peak Evolution team is developing an innovative and sustainable agricultural vehicle called TERREN, working completely with electrical power.

Kraton Corp. recently announced that it has entered into a definitive merger agreement pursuant to which DL Chemical Co., Ltd. will acquire 100% of Kraton.

According to a recent report from Grand View Research, the global chemical distribution market was estimated to be $247.1 billion last year and is projected to see robust growth (5.4% CAGR) to 2028. The distribution of specialty chemicals, such as those used in CASE (coatings, adhesives, sealants, and elastomers) and other sectors, is expected to be the fastest-growing segment of the market, reaching $139 billion in that timeframe.

Polytetrafluoroethylene (PTFE) is a high-performance plastic used in a variety of industries, particularly for its heat and chemical resistance and “non-stick” properties. However, PTFE has a low surface energy that does not allow adhesives to wet its surface and subsequently bond.
