OK-grit is a granulated iron silicate. It is an iron silicate blast cleaning abrasive made with nickelslag from the Boliden Harjavalta nickel smelter in Finland where it is pre-screened. At Sibelco Nordic’s Nakkila plant the raw material is dried, screened into different grain sizes and the dust is removed. OK-Grit is suitable for a wide range of blasting applications and also as a high-quality granule for the roofing industry. The material is produced in accordance with ISO 11126-5 and 11127.
It is used as blast cleaning abrasive for all application fields in conventional corrosion protection on almost all surfaces. Suitable for SA-3, SA-2½, SA-2 and SA-1.
