    • The present invention relates to a process for the production of coatings by coating substrates of any type with a coating composition of which the binder consists essentially of a mixture of:(a) a polyisocyanate component and(b) at least one organic polyhydroxyl compound, distinguished by the fact that the polyisocyanate component(a) is a reaction product obtained from:(i) a polyisocyanate mixture which, in addition to from about 20 to 80%, by weight, of 2,4'-diisocyanato diphenyl methane, contains a total of from about 80 to 20%, by weight, of 2,2'-diisocyanato diphenyl methane, 4,4'-diisocyanato diphenyl methane and, optionally, higher nuclear polyisocyanates of the diphenyl methane series and(ii) a polyhydroxy polyether containing at least one tertiary amine nitrogen atom and having an average molecular weight of from about 500 to 10,000 or a polyhydroxy polyether mixture containing at least one such polyhydroxy polyether and having an average molecular weight of from about 500 to 10,000.components (i) and (ii) having been reacted in an NCO:OH equivalent ratio of from about 300:1 to 10:1 to form a reaction product containing free isocyanate groups and urethane groups.
    • 本发明涉及一种通过用涂料组合物涂覆任何类型的基材来生产涂料的方法,其中粘合剂基本上由下列混合物组成:(a)多异氰酸酯组分和(b)至少一种有机多羟基化合物, 其特征在于多异氰酸酯组分(a)是由以下物质获得的反应产物:(i)多异氰酸酯混合物,除了约20至80重量%的2,4'-二异氰酸酯二苯基甲烷外, 总共约80至20重量%的2,2'-二异氰酸根合二苯基甲烷,4,4'-二异氰酸根合二苯基甲烷和任选的二苯基甲烷系列的较高核多异氰酸酯和(ii)多羟基聚醚 含有至少一个叔胺氮原子并且具有约500至10,000的平均分子量或包含至少一种这样的多羟基聚醚并且平均分子量为约50的多羟基聚醚混合物 0到10,000。 组分(i)和(ii)以约300:1至10:1的NCO:OH当量比反应形成含有游离异氰酸酯基团和氨基甲酸酯基团的反应产物。
