尼龍加纖噴PU 百格 水煮掉漆 尼龍處理劑1:3解決假性附著
?
2016/06/30

尼龍+纖噴PU亮光黑顏色,汽車上的一個工件,需要過百格,水煮測試(80度半小時),現在有用另外一家的處理劑,但是有一個不良問題,有些工件噴了會有不良品需要返噴,返噴了PU之后連底都一起掉了,懷疑是假性附著,還有尼龍處理劑不夠牢固。

給客戶寄了一款尼龍底涂劑讓其按1:3開稀,在素材表面噴一涂膜厚約3-5UM,烘烤5分鐘即可噴PU油,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,在劃線的邊緣及交叉點均無脫落。80度水煮半小時也無油漆脫落,附著力效果可達到4B以上。

尼龍底涂劑注意事項:

1、貯存于陰涼、通風、干燥處,遠離熱源。防止日曬雨淋。

2、開封后,必須密封并在一個月內使用。
