Influent Factors Of RCA Abrasion Test

The RCA test is influenced by humidity and age of paper, required for testing. New paper from the same source without wax, must be used.For the RCA Test, temperature and humidity play an important role and must be reported; as well as, how the tested material and tape used were conditioned!RCA wear tests are significantly influenced by coating thickness and substrate material’s hardness;

Influent Factors Of RCA Abrasion Test

With both coatings tested it performedbetter  higher dry film thickness.Higher functionality UV-cured coatings faired better than lower functionality.Temperature rise due to frictional heating with the corresponding change in the coefficient of friction, has an effect on the results of the test.

 

The RCA wear test is significantly influenced by coating thickness and substrate material’s hardness.PMMA performed better than PC and both coatings performed better at higher dry film thickness. In the Taber wear test the higher cross-linked coating performed better and the coating thickness had a positive effect. PC at the higher dry film thickness performed better. There is a minor difference in pencil hardness with increased coating thickness in thin films. However, there was a substantial difference based upon the substrate’s material hardness itself.
