A475 discs are specifically designed for superior sanding and finishing of hard surfaces. Ideal for use on tooling gel coats, conventional gel coats, hard composite substrates, and abrasion-resistant-coatings (such as OEM clear coats containing abrasion-resistant nanofillers or cathodic e-coated OEM replacement panels). Available in stock 5 inch and 6 inch PSA disc rolls, 5 inch PSA tabbed discs (1000 grit), and 5 inch and 6 inch hook and loop discs. Non-stock availability upon request. P-graded, premium silicon carbide grain allows penetration of even the hardest surfaces. Premium B-weight, fiber-reinforced, latex paper backing provides excellent tear strength while retaining flexibility. Open coat grain distribution and anti-clog No-Fil coating provides maximum load resistance. Rz surface finish improved versus aluminum oxide when sanding hard surfaces. Aerospace OEM approved for sanding composite fuselage and exterior components.
