Product Application of 2,2-Dimethyl-1,3-propanediol CAS# 126-30-7
Neopentyl glycol boasts a broad range of applications, primarily serving as a plasticizer in the production of unsaturated polyester resins, oil-free alkyd resins, polyurethane foams and elastomers, as well as an additive in high-grade lubricants and other fine chemicals. It acts as an excellent solvent, capable of selectively separating aromatics and cycloalkyl hydrocarbons. Endowed with water resistance, chemical resistance, and weatherability, its amino baking varnish offers superior gloss retention and resistance to yellowing. Additionally, it functions as a raw material for manufacturing inhibitors, stabilizers, and pesticides.
