Paint Formulation Using Water Based Binder and Property Studies

Abstract

Abstract Vinyl acetate – Butyl acrylate (VAc‐BuA) copolymer latices of various compositions were prepared by semicontinuous emulsion polymerization. The copolymer formed after removing the homopolymers was characterized by FTIR spectroscopy. Mechanical properties were studied by Universal Testing machine. Differential scanning calorimetry (DSC) study of copolymer showed single glass transition temperature (Tg) value confirming the absensce of graft and block copolymer. These copolymer latices were used as the binder in water based latex paint formulation. The paint prepared using 85/15 wt.% of VAc‐BuA was found to give a better paint properties. Water based paints are generally easier to apply and clean up. The surface properties found to be superior compared to commercially used paint.
