摘要
Aqueous-based basecoat compositions, useful for application to metal and/or plastic substrates, comprise an anionic polyurethane principal resin and an anionic acrylic pigment grind resin. The compositions are particularly adapted to application to substrates over a wide range of ambient humidities and have quick drying characteristics. The incorporation of an anionic acrylic grind resin, which is compatible with the anionic polyurethane principal resin, produces a coating which has good pigment wetting and dispersion characteristics with improved shelf life and color stability.
