Double-ended alcohol hydroxyl long-chain alkyl silicone oil IOTA8865H

n=30, m=3, average molecular weight 3550, hydroxyl value 25.0 (KOHmg/g) and -NCO, -COOH have high reactivity.

Product description:

It is a silicone oligomer with bishydroxy functional group, which has similar reactivity with polyol, copolymerization with -NCO and COOH, and is mainly used for synthesizing silicon modified polyurethane resin and emulsion, silicone modified polyester resin, etc. It can give the resin excellent hand feeling, improve wear resistance, prevent adhesion, antifouling and anti-graffiti.
