GLASS MICROSPHERE/PEARLS GRIT 100/200 (25 Kgs. BAG)

The Glass Microspheres Grit 100/200 are a high-quality abrasive manufactured from class A soda-lime glass. Their spherical shape and specific grain size allow obtaining uniform satin finishes on metal surfaces, being especially effective on precious metals such as gold and silver, as well as stainless steel. This type of microsphere is ideal for dry blasting processes with suction or pressure sandblasters, offering a gentle cleaning without altering the dimensions of the parts. Furthermore, its composition is free of crystalline silica, which reduces health risks and complies with occupational safety regulations. Technical characteristics: Grain size: 100/200 Hardness: 6-7 on the Mohs scale Bulk density: 1.5 g/cm³ Shape: Spherical Color: Translucent white Chemical composition: SiO₂ 70-73%, Na₂O 13-15%, CaO 7-11%, MgO 3-5%, Al₂O₃ 0.5-2% Applications: Aesthetic finishing in jewelry and watchmaking Cleaning and preparation of metal surfaces Shot peening treatments to increase fatigue resistance Removal of burrs and oxides without damaging the base surface Presentation: 25 kg bag, facilitating its handling and storage in industrial environments.
