Operation and Use:

Test pieces must be prepared in accordance with ISOR1514 and ISO2808.Place the test piece on a plate with sufficient hardness.Please install the base of the gauge flush with the surface of the coating.Operate by uniform pressure, balanced technology, and speed of 20-50mm/s.Rotates 90° and repeatedly the above operation to form a lattice pattern.Use a soft brush to brush the two diagonal lines of the grid shape 5 times back and 5 times forward slowly.Apply the tape and pull it out.Peel off the tape and observe the coating bond strength of the surface.The test is done at least three different places, but if the test results in three locations is different, please repeat the test at least three places and record all the results.

Note:

The cutter should cut the substrate to penetrate the coating but not too deep.If the coating is too thick and difficult to penetrate the test will be disabled.But we should refer to the test report.If there are special situations or special requirements, the results are related to the use of tape.The tape is generally 12.7mm translucent tape and the backing material is polyester film or cellulose acetate.Please follow the following steps: paste the tape across the grid, tear the tape at the minimum angle, and get results according to the tap area ratio.Test must be performed at a temperature of 50 ± 5% at a temperature of 50 ± 2 ° C and relative humidity.
