POLYASPARTICS WITH LONG POT LIFE AND FAST CURING

摘要

A two-component polyurea compositions including a polyisocyanate component and a hardener component. The hardener component includes at least a derivative of aspartic acid and at least one salt hydrate with a decomposition temperature of between 30° C. and 150° C. This composition allows to be applied to a large area and/or thick layers or high volume casts and shows fast curing triggered by heat but long pot life at application temperature.
