“杂化聚合加成”三聚体及其涂料

Trimers by Hybrid Additional Polymerization and The Coatings of

由混合小分子多元醇与TDI进行加成反应 ,再加入特定催化剂 ,进行三聚反应 ,可以制备出低游离TDI的多异氰酸酯预聚物和三聚体产品 。

Mixed small molecule polyols with TDI additionally polymerize, then tri-polymerize with given catalyzer. And isocyanate prepolymer and trimers with a fat lot dissociated TDI are prepared which can be used in coatings cured with curing agents or humidity.
