Description
[参考例1,実施例2および比較例1〜4]
1.試験板の調製
金属部材として、ダル鋼板(450mm×300mm×0.8mm)に、所定の工程でカチオン電着塗装(親水性樹脂成分:エポキシ樹脂、硬化剤:ブロックポリイソシアネート)を施した試験板(ニューメディアマシン社製)を用意した。
2.導電性プライマーの調製
表1に示す配合処方(単位:質量部)において、各成分を混合溶剤(トルエン/シクロヘキサン)とともに配合し、混合することにより、固形分濃度12質量%の導電性プライマーを調製した。
3.外板用試験板の有機溶剤系塗料による塗装
外板用試験板に、それぞれ導電性プライマ−を塗布した(塗布工程)。このとき、プライマー層の厚みが10μmであった。
4.外板用試験板の水性塗料による塗装
外板用試験板に、それぞれ導電性プライマ−を塗布した(塗布工程)。このとき、プライマー層の厚みが10μmであった。
(評価)
