Vitro Minerals LA-500(1)

Vitro Minerals LA-500(1) are functional fillers and extenders produced from clean, post-industrial, glass feedstocks. X-ray diffraction and scanning electron microscopy confirms that the LA Glass calcium aluminosilicate powders are fully amorphous and contain no crystalline silica. The glass chemistry results in relative chemical inertness, making LA Glass resistant to blooming, blistering, or chemical degradation in harsh environments. LA Glass powders enhance a wide range of paints, coatings, plastics, and adhesives. High consistent brightness, tint retention and stain/scrub resistance can be achieved in most paint and coating systems. LA Glass powders have low oil absorption and can be easily dispersed in water- or solvent-based systems. The feedstocks are certified post-industrial and are free from contaminants associated with post-consumer curbside glass.
