ABSTRACT:
A very high-solids polymeric dispersion, having a very low percentage of volatile organic compound is prepared by dispersing a plasticized liquid acrylic polymer in water and blending with another high molecular weight polymer dispersion and/or latex in water. This plasticized acrylic polymer dispersion has been found to be useful in combination with high molecular weight polymer dispersion and/or latex containing some smaller diameter particles in the preparation of sealant, caulk, adhesive and coating compositions. Such compositions have a polydisperse particle size distribution due to the larger plasticized liquid acrylic particles and the smaller high molecular weight polymer particles which facilitates higher particle packing densities and hence higher solids content without any undue adverse effect on the dispersion stability and rheological properties. The resulting compositions are more environmentally friendly than solvent based systems, dry quickly, and exhibit good physical properties for sealant use.
