Glass microspheres
Glass microspheres are non-metallic abrasives characterized by a uniform spherical shape, excellent resistance to breakage, and gentleness on treated surfaces. Thanks to these properties, they are ideal for sandblasting processes and as additives for paints and coatings, where they help achieve more uniform, smooth, and durable surfaces, improving material performance and reducing production costs.
