PP外殼噴漆附著工藝 炅盛PP底漆耐百格
?
2017/05/09

產品:PP底漆

型號:JS-603

用途:促進PP涂層附著,耐百格不掉漆。

案例:PP外殼噴普通漆,百格拉扯三次,表面出現大量的掉漆,附著力2B。

PP底漆解決方案:素材表面用白電油清潔干凈,PP底漆兌甲苯1:3開稀,膜厚約3-5um,65°左右烘烤5分鐘,噴普通漆,使用百格刀在表面劃劃10X10個1mm*1mm的小網格,用粘附力350 g/cm2~400g/cm2的膠帶(3M 610號膠紙或等同)進行3次百格測試。無掉漆。

PP底漆就是PP料的克星,眾所周知PP料雜,表面極性差導致附著難解決,但是PP底漆則能輕松解決涂層掉漆問題,用于PP底材的底處理,提高面漆在PP底材上的附著力,起到個承上啟下的作用。成分主要為氯化聚丙烯樹脂或氯化改性丙烯酸樹脂。

注:1、建議先小量試樣,待確認OK后再批量生產。

    2、噴涂前要做好工件表面除污的工作,以促進附著效果。
