Title:

REACTION INJECTION FORMING COMPOSITION

Document Type and Number:

Japanese Patent JPS63308020

Kind Code:

A

Abstract:

A reaction system for use in making a reaction injection moulded elastomer, said system comprising the following components : (A) a polyisocyanate composition comprising a reaction product of a stoichiometric excess of an organic polyisocyanate and : (i) a polymeric polyol having an average nominal hydroxyl functionality greater than 2 and an average hydroxyl equivalent weight of from about 500 to about 5000, and (ii) a polymeric polyamine having an average nominal primary and/or secondary amino functionality of from about 2 to about 3 and an average amine equivalent weight of from about 500 to about 5000, the polyol and the polyamine having glass transition temperatures below room temperature. (B) an isocyanate-reactive composition comprising at least one imino-functional compound.
