ZS INTERPOLYMER
SYNTRAN® water-based acrylic grades are based on proprietary technologies that can be used in a variety of protective maintenance coatings. In addition to conventional alkali-swellable and emulsion acrylics, ZS Interpolymer offers four unique acrylic technologies: dual self-crosslinking technology gives superior water, stain and chemical resistance compared to traditional self-crosslinking acrylics, anionic-cationic hybrid technology gives cationic properties with anionic compatibilities. SYNTRAN® AC 9057 is based on a proprietary self-crosslinking technology. This technology combines two different crosslinking
mechanisms on the same polymer backbone, which substantially increases the chemical resistance, stain resistance and water resistance of the cured polymer film. This technology was designed for the self-crosslinking mechanism to fully cure at room temperature, which gives 2K properties in a 1K concrete topcoat or sealer.
