阅读说明：本技术 非水性可交联的组合物 (Non-aqueous crosslinkable composition ) 是由 E·德沃尔夫 H·安德林加 J·科沃特斯 于 2020-03-17 设计创作，主要内容包括：本发明涉及包含至少一种聚丙烯酸酯多元醇的多元醇组分、包含该多元醇组分的可交联的组合物及其在涂料中的用途。更具体地,多元醇组分包含至少一种得自(甲基)丙烯酸羟烷基酯、直链(甲基)丙烯酸烷基酯、支化(甲基)丙烯酸烷基酯的单体和乙烯基单体的聚丙烯酸酯多元醇；聚丙烯酸酯多元醇的Mn为800-2,100道尔顿,Mw为1,500-4,000道尔顿,AV为0-3.5mg KOH/g多元醇,Tg为8-90℃。该可交联的组合物包含多元醇组分、多异氰酸酯交联剂和用于催化聚丙烯酸酯多元醇的羟基与交联剂的异氰酸酯基团之间反应的催化剂。该可交联的组合物可用于制造应用性能改进的涂料。(The present invention relates to a polyol component comprising at least one polyacrylate polyol, a crosslinkable composition comprising the polyol component and its use in coatings. More specifically, the polyol component comprises at least one polyacrylate polyol derived from monomers of hydroxyalkyl (meth) acrylates, linear alkyl (meth) acrylates, branched alkyl (meth) acrylates, and vinyl monomers; the polyacrylate polyol has an Mn of 800-. The crosslinkable composition comprises a polyol component, a polyisocyanate crosslinking agent, and a catalyst for catalyzing the reaction between the hydroxyl groups of the polyacrylate polyol and the isocyanate groups of the crosslinking agent. The crosslinkable compositions are useful in the manufacture of coatings having improved application properties.)
