CURABLE COMPOSITIONS CONTAINING ISOCYANATE FUNCTIONAL COMPONENTS HAVING IMPROVED DURABILITY IN THE CURED STATE

摘要

A composition comprising: a) one or more isocyanate functional prepolymers; b) one or more catalysts for the reaction of isocyanate moieties with hydroxyl groups; c) one or more reinforcing fillers; and d) a stabilizing amount of one or more compounds comprising a dihydrocarbyl hydroxyl amine an alicyclic hydroxyl amine a nitrile oxide of a dihydrocarbyl hydroxyl amine or a nitrile oxide of an alicyclic hydroxyl amine. In another embodiment the invention is a method of bonding two or more substrates together which comprises contacting the two or more substrates together with a composition according to this invention disposed along at least a portion of the area wherein the substrates are in contact. The compositions of the invention are useful as an adhesive to bond substrates together.
