Metallic water borne base coat composition.

摘要

There is disclosed a metallic and nonmetallic water borne base coat compositions exhibiting excellent appearance. A method for long term stability and the introduction of aluminum flake pigments into a water borne coating is also disclosed. The method is based on storing the aluminum flake in a solvent envirnoment with introduction of the aluminum flake in to the aqueous envirnoment just before appling the base coat coating. A water reducible acrylic resin with nonionic and acid functionality has been disclosed that allows for direct introduction of aluminum flake in to an aqueous envirnoment. The coating vehicle is based on acrylic latex vehicle which exhibits excellent drying and film properties. The coating compositions disclosed are in compliance with current and proposed volatile organic compound regulations.
