    • Polyurethane coatings which are the reaction product of A) an aliphatic, isocyanate-containing prepolymer having an isocyanate content of 1-8 wt. % and a free monomeric diisocyanate content of less than 2 wt. %, and containing 0.1 to 1.5 moles of per 1000 g of prepolymer of aliphatically bound uretdione and oxadiazinetrione groups, and B) a polyol component B) comprising at least 50 equivalent % of a compound corresponding to the formula HO—X—Y—X—OH where Y represents methylene, ethylene, —C≡C—, cyclohexylene-1,4, -1,3, -1,2, or phenylene-1,4, -1,3, -1,2 and X represents methylene, —OCH2CH2— (the oxygen being bound to the Y), or cyclohexylene-1,4, -1,3, -1,2, and where the equivalent ratio of the free NCO groups to isocyanate-reactive groups is 0.90 to 1.5. The coatings are applied to flexible substrates such as textile or leather by the casting or knife coating process by means of reactive compositions.
    • 聚氨酯涂料,其是A)具有异氰酸酯含量为1-8重量%的脂族异氰酸酯的预聚物的反应产物。 %和游离的单体二异氰酸酯含量小于2wt。 并且含有0.1-1.5摩尔的每1000克脂族酯结合的脲二酮和恶二嗪二酮基团的预聚物,和B)包含至少50当量%的对应于所述甲基的化合物的多元醇组分B)代表亚甲基,亚乙基,-C = C-,亚环己基-1,4,-1,3,...,1,2-或亚苯基-1,4,-1,3,-1,2-,X表示亚甲基,-OCH 2 CH 2 - (氧与 Y)或亚环己基-1,4,1,3 -1,2,其中游离NCO基团与异氰酸酯反应性基团的当量比为0.90至1.5。 通过使用反应性组合物的铸造或刮刀涂布将涂层施加到柔性基材如纺织品或皮革上。
