Title:
A MULTI-FUNCTIONAL POLYURETHANE OR POLYUREA OLIGOMER COMPOSITION AND A POLYMERIZABLE LIQUID WITH REDUCED VISCOSITY
Document Type and Number:
WIPO Patent Application WO/2023/232063
Kind Code:
A1
Abstract:
A blocked or reactive blocked polyurethane or polyurea oligomer composition, which comprises: a) a first blocked or reactive blocked polyurethane or polyurea oligomer, wherein the oligomer consists of a polyol moiety or polyamine moiety and multiple diisocyanate moieties, the number of the diisocyanate moieties is equal to the functionalities of the polyol or polyamine, wherein the amount of the oligomer is 10 wt. %-60 wt. %, based on the total weight of the oligomer composition; wherein the oligomer composition does not comprise any polyurethane or polyurea oligomer wherein both NCO-groups of the diisocyanate are reacted with both the polyol and a diol, or with both the polyamine and a diamine.
