UNIGRIT blasting abrasive
UNIGRIT abrasive
UNIGRIT is a high-quality blasting abrasive intended for professional abrasive blasting of steel, concrete, reinforced concrete and stone surfaces. UNIGRIT is produced from copper slag and is used wherever effective removal of rust, mill scale, old paint coatings, technological contaminants and surface preparation before painting and anti-corrosion protection are required.
The product meets the requirements of PN-EN ISO 11126-3 for non-metallic abrasives used for surface preparation before applying protective coatings. UNIGRIT enables surface preparation in accordance with ISO requirements in classes SA 1, SA 2, SA 2½ and SA 3. As a result, copper slag abrasive is suitable for demanding anti-corrosion works on steel structures.
UNIGRIT copper slag abrasive has an amorphous structure, which means that the silicon dioxide (SiO₂) it contains occurs in the form of stable silicate compounds. The free silica content does not exceed 1%, which helps reduce harmful dust generated during blasting. Therefore the abrasive can be used safely in surface cleaning processes in accordance with applicable industrial requirements. UNIGRIT may be used in abrasive blasting processes carried out in accordance with occupational health and safety requirements, including German DGUV Regel 100-500 Paragraph 3.2, Chapter 2.24 (Work with abrasive agents).
Applications of UNIGRIT abrasive
UNIGRIT copper slag abrasive is used in abrasive blasting of steel, concrete and reinforced concrete surfaces. Thanks to high hardness and angular grain structure, it effectively removes contaminants, corrosion and old protective coatings, preparing the substrate for further technological processes.
Common applications of UNIGRIT abrasive:
- cleaning steel structures
- surface preparation before painting
- surface preparation for anti-corrosion coatings
- removal of rust and corrosion products
- removal of old paint coatings
- removal of mill scale
- cleaning bridges, viaducts and engineering structures
- cleaning storage and process tanks
- cleaning pipelines and industrial installations
- surface preparation in shipbuilding and offshore industry
- renovation of stone and concrete façades
- treatment of concrete and reinforced concrete
- surface preparation before thermal spray metallization
- cleaning machines, equipment and industrial infrastructure
Industries using UNIGRIT abrasive
Due to its high cleaning efficiency and the ability to obtain the required surface roughness, UNIGRIT copper slag abrasive is used in many industries, especially in:
- shipbuilding industry
