Silicone modifier STD-26404

Descriptions

STD-26202 is a terminal hydroxyl alkyl modified silicone copolymer, tetrafunctional, with high reactivity of hydroxymethyl terminal functional group-CH2OH, the reactivity is much higher than that of ordinary hydroxyl silicone oil with Si-OH as the reaction functional group, at the same time, because it has a phenyl group, it has good compatibility, through the reaction of its terminal hydroxyl group and isocyanate, silicone components can be introduced into the polyurethane material, so as to improve the low temperature flexibility, water resistance, slip heat resistance, tear resistance and other properties of the polyurethane material.

Physics and Chemical properties
