    • The invention provides novel isocyanate-based compounds. Such novel compounds can be used in essentially all applications where conventional isocyanate-based compounds are employed. In other words, the novel isocyanate-based compounds can be used in the making of liquid and powder coating compositions, adhesives, rigid and moldable plastics and foams. The isocyanate-based compounds of the present invention include a polyfunctional isocyanate compound which is at least partially blocked with at least one of the following: a polyhydroxy aromatic compound, or a mixture of a polyhydroxy aromatic compound and a hydroxy-functional ester compound. The present invention further provides compositions which include the aforementioned novel isocyanate-based compound as a component. These compositions can be in the form of liquid coating compositions, powder coating compositions, powder slurry coating compositions, plastic compositions, adhesive compositions, or polymeric foam compositions.
    • 本发明提供了新颖的基于异氰酸酯的化合物。 这些新型化合物可用于基本上所有使用常规的异氰酸酯基化合物的应用。 换句话说,新的异氰酸酯基化合物可用于制备液体和粉末涂料组合物,粘合剂,刚性和可模塑的塑料和泡沫。 本发明的异氰酸酯类化合物包括多官能异氰酸酯化合物,其至少部分被至少一种以下的一种阻塞:多羟基芳族化合物或多羟基芳族化合物和羟基官能酯化合物的混合物。 本发明还提供了包含上述新型异氰酸酯基化合物作为组分的组合物。 这些组合物可以是液体涂料组合物,粉末涂料组合物,粉末浆料涂料组合物,塑料组合物,粘合剂组合物或聚合物泡沫组合物的形式。
