摘要：
A one-part moisture-curing liquid-applied waterproofing membrane as disclosed includes a polyurethane polymer obtained from at least one polyether polyol and at least one diisocyanate, and an aldimine of the formula (I). The membrane has a long shelf life stability with both aromatic and aliphatic isocyanates, a low viscosity at low solvent content, a sufficiently long open time to allow hand application and cures fast to a solid elastic material of high strength and high elongation. The released aldehyd is non-toxic and low flammable and evaporates quickly out of the membrane causing only minimal odour emission. The membrane has high crack-bridging qualities in a broad temperature range and is easily overcoatable without interlayer adhesion problems, which makes it particularly suitable for roofing applications.
