Abstract

Statistical methods were used to develop hydroxy functional acrylic emulsions for use with a water-dispersible polyisocyanate crosslinker. The resulting two-component waterborne coating systems were optimized for kitchen cabinet and office furniture applications. Key performance criteria included appearance and aesthetics, pot life, print and mar resistance, and chemical resistance involving both Kitchen Cabinet Manufacturers’ Association (KCMA) and office furniture requirements. Statistical analysis revealed several strong correlations between acrylic emulsion hydroxy level, particle size, composition Tg, polymerization process and wood coating performance. For example, smaller acrylic emulsion particle size was found to yield many performance benefits with few detriments.
