Abstract

Project objective is to develop a technology of New aqueous silicone-acrylic dispersion with particle size of ca. 100 nm and hybrid structure via emulsion polymerization method at pilot and semi-technical scale. Hybrid dispersion will be used as binder for water-reducible architectural paints, in particular for external building facades. Using that new dispersion would lead to improved application properties of silicone-acrylic paints that are currently produced from mixture of styrene-acrylic and silicone dispersions what results in decreased miscibility with pigments and phase separation at paint storage as well as in formation of less uniform coats which are less resistant to soiling. Project objective will be achieved by determination of the method of dispersion synthesis and composition of its silicone and acrylic part on properties and structure of dispersion particles as well as coatings and paints, and selection of optimum solution followed by upscaling.
