Effect of relative humidity to pressure sensitive correction tape?

Question

Hi there. Usually performance of correction tape is related to the factor of temperature and relative humidity. Higher temperature environment can promote migration of adhesive to the back of foundation tape can causing blocking defect. How about relative humidity can affect the performance? Thanks.

Answer 1

since most of the PSAs out there are acrylic, they are adversely affected by humidity. Loss of adhesion to both substrate and backer is expected. also, some swelling pror to failure would be expected.

Answer 2

Have you conducted the relevant experiments ??????
