BLOCKED ISOCYANATE-BASED COMPOUNDS AND COMPOSITIONS CONTAINING THE SAME

摘要

The invention provides novel isocyanate-based compounds. Such novel compound s 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 composition s, 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 nov el 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.
