Cross-scratch adhesion TesterAccording to ISO 2409 and ASTM D3359, the ability of the coating to resist separation from the substrate is determined when cutting a lattice pattern on the coating.
All tools and accessories needed to perform the cross-scratch test are included.Ergonomically designed tool grip with non-slip grip for comfortable all-day use.The rotatable cutting head ensures proper positioning and uniform cutting surface pressure.Easy-to-change, hardened steel blade with 4 cutting edges for longer testing.Tapes are available in accordance with ISO 2409 or ASTM D3359.
