Advantages of using PolGrit abrasive

• enables obtaining any degree of surface cleaning according to the Swedish standard SIS 055900-1967 and PN-70/H-97050
• produced abrasive meets the requirements of DIN 8201 part 9 and TRGS-503
• enables optimum surface roughness and development
• provides the highest cleaning performance among non-metallic abrasives
• consumption of PolGrit abrasive is much lower than the consumption of sand, and this difference increases as the degree of corrosion of the sheet metal increases.

Application of PolGrit abrasive

• shipyards : cleaning of sheet metal, ship hulls, equipment
• steel structures, bridges, viaducts, storage tanks, pipes, pipes, pipe transport
• land and water structures, finishing of concrete elements of building facades, foundations, ceilings, cleaning of boiler heating surfaces
• removal of old paint coatings, rust, scale, layers of plastic
• preparation of metal surfaces for sets of chlorinated rubber, polyvinyl, epoxy, polyurethane and special antifouling paints and for metallization

The PolGrit® abrasive has received a test certificate from the Institute for Occupational Safety of Professional Associations – BIA – 4052220113.

According to the opinion of the Institute of Occupational Medicine in Sosnowiec, from the point of view of its harmfulness to health, PolGrit® abrasive is a much safer material than the traditional abrasives used so far, especially sand.

It is a chemically inert material, does not react with the treated surface and does not cause secondary corrosion.

It is non-flammable, non-hygroscopic and non-magnetic.

The polGrit® abrasive is certified for compliance with the PN-EN ISO 11126-3 standard, excluding the specific density parameter (item 6.2, table).

It does not contain petroleum substances.

PolGrit abrasive has been tested for the content of natural radioactive substances.

Subject of the warranty

The Abrasives Plant of the Institute of Non-Ferrous Metals Branch in Legnica guarantees to the purchaser-end user that the purchased polGrit® abrasive meets the technical requirements for non-metallic abrasives made of copper slags used in abrasive blasting and complies with the PN-EN ISO 11126-3 standard.

Warranty period

Subject to further provisions, the Abrasives Plant of the Institute of Non-Ferrous Metals Branch in Legnica provides the purchaser with a warranty for the purchased polGrit® abrasive for the period of 2 years from the date of receipt of the goods.

Warranty Policy

The Department of Abrasives of the Institute of Non-Ferrous Metals Branch in Legnica informs that in accordance with the PN-EN ISO 11126-3 standard, section on grain composition, the presence of oversize in polGrit® abrasive in the amount consistent with the assortment is not a defect of the abrasive. Therefore, in order to avoid blockages during sandblasting, it is recommended to preventively use a sieve on the grit for the sandblaster with a mesh at least 4 times larger than the upper granulation range of the purchased polGrit® abrasive. As soon as the goods leave the premises of the Abrasives Plant of the Institute of Non-Ferrous Metals Branch in Legnica, the manufacturer is not responsible for the moisture content of the purchased abrasive, which depends on the conditions in which the goods are transported and stored at the buyer’s premises.
