Patent ID: 7288288

Claim:
A process for coating a substrate which comprises applying a one-coat layer on a substrate using a coating composition and curing said coating composition; wherein said coating composition comprises (a) 10 to 60 wt. % of a functionalized solid resin having functional groups selected from the group consisting of hydroxy-, carboxy- amino- and any mixtures thereof and wherein the functionalized solid resins have a linear, branched or star structure and are selected from the group consisting of methacrylic resins, acrylic resins, polyester resins, polyurethane resins, and epoxy modified resins, (b) 5 to 40 wt. % of at least one crosslinking agent for component (a), selected from the group consisting of hydroxyl, carboxyl, amide or amino group containing crosslinking agents, cycloaliphatic, aliphatic or aromatic polyisocyanates, epoxy group containing crosslinking agents, and carboxy-functional polymers; (c) 5 to 70 wt. % of filler material selected from the group consisting of aluminum hydroxide, alumina monohydrate, calcium carbonate, magnesium hydroxide and barium sulfate, (d) 2 to 40 wt. % of a ground polymer material based on polymethyl methacrylate filler which is a filled polymer material comprising about 40 wt. % polymethyl methacrylate and about 60 wt. % of aluminum hydroxide, (e) 10 to 35 wt. % of organic solvents selected from the group consisting of glycol ethers, glycol ether esters, ketones, aromatic hydrocarbons, aliphatic hydrocarbons and any mixtures thereof; (f) 0.01 to 15 wt. % of additives and pigments and (g) 2 to 30 wt. % reactive thinners selected from the group consisting of ketimines, aminofunctional compounds and mixtures thereof.
