We are formulating acrylic adhesives (both reactive acrylics and anaerobics), but are having problems with the sourcing of monomers. Some suppliers can’t seem to give us monomers that produce shelf-stable products, even though they purport to have added extra free-radical stabilizers. Can you offer some advice?
As in previous years, this year’s handbook has been updated with many new products and definitions. The listings are divided into five major categories: Additives and Chemical Specialties; Oils and Fatty Acids; Resins and Base Polymers; Pigments and Dyes, Dry/Dispersions and Extenders; and Solvents.
Troysol™ 382 is a new multifunctional, silicone-free wetting additive that reportedly promotes strong dynamic surface tension reduction in aqueous systems, resulting in excellent wetting and application characteristics.
Arkema Inc. recently announced it has signed a distribution agreement with Lipscomb Chemical Co. Inc. to carry its industrial range of Orgasol® powders and the fine powders additives segment of the Rilsan® fine powder product line.
Troysol™ Z372 is reportedly a high-performance universal mar and slip additive that can improve the wetting of low-surface-energy and contaminated substrates, resulting in uniform film coverage.
A new, single fluorosilicone additive option is available to formulators of solventborne coatings and solventless radiation-curable coatings to control foam generation without causing surface defects or changes in the gloss and haze of the applied film.
