[0090] Example 1-2, Comparative Example 1-3 Appearance, paint film adhesion, process VOC are compared as follows:
[0091]
[0092] Analysis of Example 1 and Comparative Example 1 shows that the flash-off temperature is low, the water content of the primer after flash-off is high, and the high-water-content electroplating silver is sprayed on the primer interface, causing the water-based high-brightness silver and the water-based primer to bite the bottom, and the appearance is poor.
[0093] Analysis of Examples 1, 2 and Comparative Examples 2 and 3 shows that the use of water-based primer for full spray can solve the problem of blackening in the unpolished area, ensure the consistency of product appearance, and can effectively reduce construction VOC.
[0094] Analysis of Example 1 and Comparative Example 4 shows that the use of pure polyester powder and high-leveling water-based black matrix can solve the problem of orange peel of epoxy polyester powder, especially in the...
