Ichemco Internal Test Methods

Peel Adhesion on Steel

Id:11
Measure unit:g/in
Procedure:Condition a coated sample for about 1 hour. Clean carefully the test panel with acetone and absorbent cleaning material, avoid contact with fingers. From a representative sample of material, cut some strips (1in wide and 12in long). Apply one end of the specimen to the border of the test panel. Hold the other end of the specimen so that it doesn't go in contact with the panel but is positioned loosely above it. Roll once in each direction with the 4.5 lbs hand roller or with a Rolldown Machine (12 in/min, 4.5 lbs PSTC rollers). Wait for 20 minutes before proceeding with the measurement. Double back the free end of the strip at an angle of 180°. Fix the panel to the mobile clamp of the peel adhesion tester (or tensile tester), and fix the folded end to the other clamp. Operate the instrument at 12.0 in/min speed and report the average pull value obtained during the peeling . Standard room condition: temperature 20-22°C.
