The average molecular weight of 4250 single-ended dihydroxy structure has high reactivity with -NCO, -COOH
Product description:
It is a single-end bis-hydroxy terminated silicone prepolymer with similar reactivity with polyol. It can be copolymerized with -NCO and COOH. It is mainly used for synthesizing silicon modified polyurethane resin and emulsion, and silicone modified poly. Ester resin, etc., can give the resin excellent hand feeling and improve wear resistance. Prevent adhesions, stains and graffiti.
