    Abstract: The present invention describes a one-part moisture-curing liquid-applied waterproofing membrane comprising 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 flam- mable 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.

    Abstract translation: 本发明描述了一种包含由至少一种聚醚多元醇和至少一种二异氰酸酯获得的聚氨酯聚合物和式（I）的醛亚胺的单组分湿固化液体防水膜。 该膜与芳族和脂族异氰酸酯具有长的保质期稳定性，在低溶剂含量下具有低粘度，足够长的开放时间以允许手施用并且快速固化到具有高强度和高伸长率的固体弹性材料。 释放的醛是无毒的，可燃性低，并快速蒸发出膜，仅产生极少的气味。 该膜在宽温度范围内具有高裂纹桥接性能，并且易于过涂覆而没有层间粘合问题，这使得其特别适用于屋面应用。

    Abstract: A natural oil derived blocked prepolymer is a reaction product of a composition including an isocyanate terminated prepolymer that is the reaction product of a mixture that has at least one or more polyols including at least one polyol having a secondary amine initiator or a tertiary amine initiator and a stoichiometric excess of one or more organic polyisocyanate components of which the stoichiometric excess of isocyanate to alcohol moieties (NCO:OH) is from 1.1:1 to 4:1, and a natural oil derived blocking agent. The viscosity of the natural oil derived blocked prepolymer is from 50,000 Pa*s to 300,000 Pa*s. An acrylic plastisol composition comprises the natural oil blocked prepolymer, one or more acrylic powders, one or more plasticizers, one or more amine cross-linkers, and optionally, one or more fillers.
