LA-400, a glass powder, is an oxide that is combined in an amorphous state in a calcium aluminosilicate glass. Under a microscope, LA Glass powder particles are transparent, angular-shaped, with like dimensions in the x, y and z axis. X-ray diffraction and scanning electron microscopy indorses that the LA Glass calcium aluminosilicate powders contain no crystalline silica and are fully amorphous. LA Glass powders improve a wide range of plastics, paints, adhesives, and coatings. Stain/scrub resistance, tint retention, and high consistent brightness can be attained in most coating and paint systems. LA Glass powders can be effortlessly dispersed in solvent- or water- based systems and has low oil absorption (24). LA-400 has a specific gravity of 2.45, a bulk density of 45 lb/ft3, a pH of 10.5, and a refractive index of 1.47 to 1.51.
Vitro Minerals, headquartered in Conyers, Georgia, has developed innovative glass products for use as crystalline silica free blasting media, functional fillers for the coatings, plastics, and sealants industries, and mineral admixtures for concrete. Vitro Minerals LA Glass grades offer excellent consistency in particle size, brightness, and hegman grind. LA Glass products have very high brightness and corrosion resistance rendering them inert in both solvent & water based coating systems. In addition to chemical inertness, LA Glass offers excellent abrasión resistance and low oil absorptions.
