Surface Treatment
PST-1128 — Pre-Printing Surface Treatment
Surfaces coated with VueGuard® 901 and TopPro® High Performance UV-curable Coatings require a pre-printing surface treatment before any inking process, due to their highly chemical resistant nature. This treatment ensures good adhesion of ink to the coated surface.

Cleaning Procedure
Procedure for cleaning coated parts before the inking process:
-
1Wet a lint-free, polyester wiper with the PST formulation. Apply some pressure with the wet wiper over the substrate in even strokes, then dry with a clean, lint-free, polyester dry wiper.
-
2Wet a wiper with Propyl Alcohol or IPA. Clean with even strokes, then dry with a dry, lint-free wiper.
-
3If streaks appear, repeat step 2. PCI Labs highly recommends applying the VueGuard® 901 or TopPro® UV-curable high abrasion and chemical resistant hard coats on top of your printed surfaces for best results.
