While they only make up a tiny fraction of an end product, trace impurities can make up a large part of consumers’ perceptions.

Formulators working with these next-generation solvents can provide enhanced properties to discerning consumers seeking high-performance paints made with readily biodegradable solvents that are low in odor and offer improved rheology.

This application study shows that biobased SA can be used as a diacid to replace IPA and AA in a polyester resin for metal coatings.

The new rheological additive (RA) produces strong initial anti-sag results, even under these very low-energy mixing conditions with no added heat. The stability following accelerated aging is also greatly improved relative to the commercial RAs. The new RA activates quickly and does not require a lengthy heat up period during paint or adhesive manufacturing.
