Water absorption

2002

Dear Sir,

We produce PVC-Plastisol for car under body coating and body sealer; recently we are facing a moisture absorption problem which result air bubbles and blisters. The problem comes out after second bake (140 C, 30 min), which the previous process is kept for 3 days from first bake (140 C, 30 min) My Question, do you have any idea to add effective anti-moisture instead of CaO.

Best regards,
