Product Description

It is a silicone prepolymer with dihydroxyl functional group, which has similar reactivity to polyols and copolymerizes with -NCO. It is mainly used for synthesizing silicone modified polyurethane resin, polyurethane emulsion and Si -TPU, which can give the resin excellent feel, improve wear resistance, prevent adhesion, anti-fouling and anti-graffiti.
