Perlite filler ideally meets all the requirements for the production of textured paints and coatings: very low bulk density (about 80-120 kg / m3); rough structure for good adhesion; translucent white - an intrinsic reflection property that allows the pigment to create a strong, uniform white color; very hard structure, resistant to abrasion and grinding; ensuring the properties of thermal protection and fire protection in textured paints due to the foam structure of the particles.
