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;  

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.
 
PMMA performed much better . The Steel Wool test verified better performance vs. Higher crosslinking density.The best performer was PC at the smaller dry film thickness.The RCA test is influenced by humidity and age of paper, required for testing. Newpaper from the same source without wax, must be used.

The tape abrasion test machine having a number of times to reach the stop function and having breaks down function, which can reduce product testing abrasion tests error, better test for a customer to save paper.
