Urethane resin and a manufacturing method thereof

Abstract: silicone reactive group is an alkoxysilyl group, the main chain in the urethane resin typified by polyether structure, to impart adhesive properties essentially good storage stability, end increasing the flexibility of the alkoxysilyl group structure, to provide a urethane resin capable of modulating freely curing rate. An alpha, was converted to the alkoxysilane having one secondary amino group structure the amino group of the aminosilane by nucleophilic addition reaction to the unsaturated bond of β- unsaturated carbonyl compounds, isocyanate terminated this It is added to the urethane prepolymer.
