Antara™ 430 (Polectron™ 430) polymer
Antara (Polectron) 430 polymer is a white, thermoplastic, 38-41 percent solids, latex produced as a graft, emulsion copolymer of 30 percent polyvinylpyrrolidone and 70 percent styrene in the presence of an anionic surfactant. The size distribution of the emulsion is such that 90 percent of the particles are less than 0.5 micron with a maximum 25°C viscosity of 750cps at pH 2.0-5.0. Antara (Polectron) 430 polymer is a highly effective opacifier.
With a glass transition temperature of approximately 100°C, it forms transparent, thermoplastic films that readily adhere to glass, plastics and metals. Antara (Polectron) 430 polymer is thermally and mechanically stable in the presence of a variety of ionic compounds.
Polectron 430 polymer is sold as Antara 430 polymer in Europe and Asia Pacific.
