Main Partial thickness of the decoration surface ≥60μm

Indentation harness

indentation resistance of coating ≥80

Adhesive Quality

The dry,wet and boiling adhesive quality of the coating shall reach level 0.

Impact resistance

the coating shall have no cracking or shreds after cup drawing testes.

Bending resistance

The coating shall have no cracking or shreds after bending tests.

Appearance quality

The coating on the decoration surface of the powder spraying profiles shall be smooth,even and
