3. Masking evaluation

Test Piece Condition

Baking paint conditions:
Apply the baking paint as following process.
Electrode position coated steel plate ⇒ Under-coating (black, baking at 160°C for 30 min)
⇒ Put Masking tapes (PVC8030 / PVC8032) ⇒ Middle-coating (white, baking at 160°C for 30min) ⇒ Top-coating (clear, baking at 160°C for 30 min)
Left at RT, remove the masking tapes (peeling speed: 300mm/min).
Then, evaluate the following characteristics.

Measuring method
Adhesive residue: Visual check of adhesive residue on under-coat.
Paint edge sharpness: Visual check of the paint edge sharpness of under / middle / top-coat.
Tarnish: Visual check of tarnish of the masked surface on the under-coat.
Flaking: Visual check of flaking from middle/top-coats.
