Title:
HEAT-CURING SEALANT COMPOSITIONS HAVING FAST SKIN FORMATION AND HIGH TENSILE STRENGTH
Document Type and Number:
WIPO Patent Application WO/2012/084806
Kind Code:
A3
Abstract:
The invention relates to heat-curing sealant compositions including at least epoxy resin, dicyandiamide or an amine complex of a Lewis acid, polyurethane polymer (PUP) comprising isocyanate groups and polyaldimine. Said one-component sealant compositions are characterized by fast skin formation and high tensile strength. Due to short skin formation time, said compositions are optimally suitable for use as sealants in autobody work because a CDP paint can be excellently layered on top of same.
