POLYUREA COMPOSITIONS AND METHODS OF USE

摘要

PROBLEM TO BE SOLVED: To provide polyurea compositions comprising reaction products between a polyformal-isocyanate prepolymer and a curing agent comprising an amine.SOLUTION: The present disclosure relates to polyurea compositions and methods of using the polyurea compositions. Disclosed are polyurea compositions comprising products of a reaction between a polyformal-isocyanate prepolymer and a curing agent comprising an amine. The compositions are useful as sealants in aerospace applications. Polyurea compositions for use as sealants having enhanced properties useful for aerospace sealant applications are provided.SELECTED DRAWING: Figure 1
