CURABLE SILANIZED URETHANE RESIN AND ADHESIVE SILANIZED URETHANE RESIN COMPOSITION

摘要

PROBLEM TO BE SOLVED: To provide a curable silanized urethane resin which is adjusted to low viscosity while environmental load is reduced and safety is secured.;SOLUTION: The curable silanized urethane resin is synthesized by allowing a crosslinkable silane compound (D) having, in its molecule, an active hydrogen group which can react with an isocyanate group, to react with a urethane resin having an isocyanate group in its molecule. The urethane resin having the isocyanate group in its molecule is synthesized by allowing an organic polymer (A) having a hydroxyl group in its molecule to react with a compound (B) having an isocyanate group in its molecule by using a zirconium based compound (C) as a catalyst.;COPYRIGHT: (C)2011,JPO&INPIT
