遮盖力弱
油漆缺陷
成因
- Color of undercoat substrate not matched to the topcoat colour
基材底漆的颜色与面漆颜色不匹配
- Basecoat or topcoat over-thinned 底色漆或面漆过薄
- Paint not applied uniform 漆面喷涂不均匀
- Film build of topcoat too low 面漆膜厚过低
预防
- A uniform adapted substrate is required, especially when you apply translucent colors (e.g. 3-stage pearl effect finishes)
在喷涂半透明颜色(例如三涂层珍珠效果漆)时，需要具有均匀且匹配的底材。
- Mix paint according to technical data sheets
遵照TDS进行油漆调配
- Use the recommended ground coats for poor-covering colours
对于遮盖力差的颜色，使用推荐的底色漆。
- Ensure sufficient film thickness and respect appropriate flash-off intervals between coats
确保足够的膜厚，并遵守各涂层之间的适当闪干时间。
如何修补
- After drying, sand lightly and repaint 干燥后，请问打磨并重新喷涂。
