Test Method Description

Scratch Repairing Function: Use a copper brush with a copper wire within 0.1mm. After brushing the coating surface for 10 times in a circular manner, after heating it with a baking gun or 100°C boiling water, visually inspect the disappearance of fine scratches; disappearance of fine scratches.
Acid and Alkali Resistance: 10% hydrochloric acid, 0.1mol/L sodium hydroxide solution, after smearing the surface of the sample and leaving it for 24 hours, evaluate the appearance of the sample without visible bubbles, cracks and other coating defects.
Anti-Stain: Use equipment with UV radiation, heating and spraying functions to damage the sample, refer to the corresponding provisions of GB/T 16422.2 for parameter setting, and the spraying water uses general industrial water.
