blast-cleaning abrasives. IRGRIT ® is vitreous amorphous that
absorbs no water but may be wetted on the surface only.
IRGRIT ®is available in 36 different particle sizes derived from mixing eight main produced particle sizes from Turbo ++ to HD++ which enable the user to choose the correct grade based on requirement of cleanliness level (Sa 2, 2.5, 3) and anchor profile (25 – 150 microns).
IRGRIT
® is approved by major shipyards, oil and gas companies,
paint manufacturers, coating contractors, tank builders and pressure vessel fabricators,
offshore yards and construction chemicals. |
