1,4-Butanediol 1,4-Butanediol 110-63-4 Crompton-Uniroyal Chemical Crosslinking / Coupling / Curing Agents >> Diol / Triol Polyesters PU - Prepolymers 1,4 Butanediol Diol Urethane Curative 1,4-Butanediol is a colorless and almost odorless liquid that can be used to cure urethane prepolymers. It is especially useful with MDI terminated prepolymers. This hygroscopic diol is soluble in water, alcohols, esters, ketones, glycolethers and glycol ether acetates; immiscible in aliphatic and aromatic hydrocarbons and diethylether. It is also used as a plasticizer and cleaning agent. Hygroscopic, colorless and almost odorless 1,4 butanediol. Used with MDI terminated prepolymers to cure urethane prepolymers. Also used as intermediate for the production of polyether diols, urethane and polyester polymers, and as a plasticizer and cleaning agent.
