Abstract: Solid compositions made from or coated with a non-melting organic polymer having a main glass transition temperature of at least 65° C., few if any isocyanate groups and a wet aged glass transition temperature of up to 60° C. are self-bonding materials that are useful in a variety of adhesive and molding operations. Under conditions of heat and moisture, these compositions will self-bond. The compositions can be used as adhesive coatings, which are solid and non-tacky and thus can be transported and stored easily under ambient conditions. These compositions are especially useful in applications in which, due to the location and/or orientation of the substrates, liquid or melting materials cannot be applied easily or will run off the substrates.

Abstract translation: 由具有至少65℃的主要玻璃化转变温度的非熔融有机聚合物制成或涂覆的固体组合物，几乎没有异氰酸酯基团和高达60℃的湿老化玻璃化转变温度是自粘合的 可用于各种粘合和成型操作的材料。 在热和水分的条件下，这些组合物将自粘结。 组合物可以用作粘合剂涂层，其是固体和非粘性的，因此可以在环境条件下容易地运输和储存。 这些组合物特别适用于其中由于基材的位置和/或取向而使液体或熔融材料不能容易地应用或将从基材流出的应用中。
