Product Application of 2,2-Dimethyl-1,3-propanediol CAS# 126-30-7
Neopentyl glycol has a wide range of uses, mainly as a plasticizer for the production of unsaturated polyester resins, oil-free alkyd resins, polyurethane foams and elastomers, an additive for advanced lubricants and other fine chemicals. Neopentyl glycol is an excellent solvent and can be used for the selective separation of aromatics and cycloalkyl hydrocarbons. Neopentyl glycol is resistant to water, chemicals and weathering. Its amino baking varnish has good gloss retention and does not turn yellow. It can also be used as a raw material for the production of inhibitors, stabilizers and pesticides.
