POLARITE 103A is a calcined kaolin treated with a vinyl functional silane that provides enhanced performance in surface applications. As a treated calcined kaolin, POLARITE 103A delivers superior brightness and fineness. Its high purity and controlled particle size distribution results in improved rheology and application properties. These characteristics make POLARITE 103A well-suited for formulations where opacity, smoothness and durability are important. POLARITE 103A can disperse readily and provides a smooth surface finish, hiding imperfections. Its functional treatment also promotes adhesion in multi-layer systems. With its benefits, POLARITE 103A is a top choice for applications where a flawless appearance and long-lasting performance are required.
