で表される化合物が挙げられる。当該一般式[II]で表される化合物は、式中nが1又は2の単一化合物、及びポリシロキサンジアミンを包含する。
得られた電着塗料組成物を電気泳動法光散乱法(レーザードップラー法)での粒径分析装置ELS−Z2(大塚電子株式会社製)を用いて測定し、測定結果をキュムラント解析法にて解析した。
試験はJISC3003「11.2」B法にて短絡した温度を測定した。試料はφ1mm、長さ30cmの銅線を電着し、乾燥は80℃で5分間後、220℃で30分間行い、得られた試料の被膜厚みは19〜24μmとなった。このときの皮膜厚さの測定方法はあらかじめ銅線の外径(D1)を測定し、被覆後の外径(D2)を測定して、次の計算で算出する。皮膜厚さ(μm)=(D2−D1)/2
試験はJIS5600 4-4のひっかき硬度試験にて測定した。試料は厚さ1mmの銅板を電着し、乾燥は80℃で5分間後、220℃で30分間行い、得られた試料の被膜厚みは19〜24μmとなった。
密着性の確認はJISK5600クロスカット法にて行った。測定する碁盤目(分母)を100個とし、はがれなかった枡を分子として評価した。使用した試料は前記表面硬度のものと同じ方法で被膜を形成したのち、さらに250℃の高温にて2時間処理したものを使用した。
試験用の試料は幅10mm、厚さ0.5mm、長さ300mm平角銅線に40〜50μmの厚膜を形成し、さらに250℃にて2時間の高温処理を行うことで、その耐熱性能を確認した。高温処理後、この平角銅線を厚さ方向に曲げR1mmにて180°折り曲げて、その外周部にて割れ、内周部にしわが生じないかを目視にて確認した。
