US20070238837A1 Compounds containing allophanate, isocyanate and ortho ester groups and their use as binders 审中-公开
含有脲基甲酸酯，异氰酸酯和原酸酯基团的化合物及其作为粘合剂的用途

Compounds containing allophanate, isocyanate and ortho ester groups and their use as binders
摘要：
The present invention relates to a process for preparing compounds which contain allophanate groups, free NCO groups and polyortho ester groups by reacting A) one or more aliphatic and/or cycloaliphatic polyisocyanates with B) one or more polyortho esters containing at least one hydroxyl group per molecule to form NCO-functional polyurethanes and then reacting some or all of the urethane groups to form allophanate groups. The present invention relates to compounds obtained by this process and to their use as binders in coating, sealant and adhesive compositions that also contain catalysts and optionally additives.
摘要（中）：

本发明涉及通过使A）一种或多种脂族和/或脂环族多异氰酸酯与B）一种或多种含有至少一个羟基的聚原酸酯来制备含有脲基甲酸酯基团，游离NCO基团和聚酯酯基团的化合物的方法 分子以形成NCO官能的聚氨酯，然后使一些或所有的氨基甲酸酯基团反应形成脲基甲酸酯基团。 本发明涉及通过该方法获得的化合物及其作为粘合剂在包含催化剂和任选的添加剂的涂料，密封剂和粘合剂组合物中的用途。
