Note: Due to the complexity of the cross section of the extruded profile, the thickness of the paint on certain surfaces of the profile (such as internal corners, lateral grooves, etc.) is allowed to be lower than the specified value of the table, but the phenomenon of bottoming is not allowed.
 
Gloss The 60-degree gloss value is consistent with the contract, with a deviation of +/- 5 gloss units Appearance quality The coating should be smooth and uniform, and no wrinkles and bubbles are allowed to fall off and affect the defects.
Color and color difference Basically consistent with the contract standard swatches Hardness ≧1H
Adhesion Dry, wet and boiling water adhesion should reach level 0 Impact resistance No cracking or falling off after frontal impact test

After the agreement between the supplier and the buyer, the performance test of the product may not be carried out, and the performance of the product may be inferred by similar products, and the performance test results of similar products shall comply with the requirements in the table.
Appearance quality: The composite part of the strip insulation profile allows slight cracking of the coating, but does not allow the substrate to crack.
