Water borne high solids coating compositions are made by blending a water-dispersible, crosslinkable organic polymer free of amide groups, water, at least one reactive urea derivative, a crosslinking agent and optionally a crosslinking catalyst. Optionally a mixture of reactive urea and carbamate derivatives can be used.
The resultant water borne high solids coating compositions can be either solutions or dispersions depending upon the particular polymer and reactive urea or carbamate chosen as the reactive cosolvent or reactive diluent.
水性高固体份涂料组合物是通过混合一种不含酰胺基团的水分散性可交联有机聚合物、水、至少一种活性脲衍生物、一种交联剂和一种交联催化剂制成的。也可选用活性脲和氨基甲酸酯衍生物的混合物。
由此产生的水性高固体份涂料组合物既可以是溶液,也可以是分散体,这取决于作为反应性助溶剂或反应性稀释剂的特定聚合物和反应性脲或氨基甲酸酯的选择。
