Abstract
The present invention describes a one-part moisture-curing liquid-applied waterproofing membrane having a polyurethane polymer, a long-chain aldimine and a hardener selected from an oxazolidine and another aldimine. The membrane has a low viscosity at low solvent content and a good shelf life stability and cures fast to form a solid elastic material. The membrane is particularly suitable for roofing applications, possessing high strength, high elongation and good durability under outdoor weathering conditions in a broad temperature range.
