表1に示した如く、配合物質及び配合割合を変更した以外は実施例1と同様の手順で硬化性組成物を調製した。
JIS A 1439に準じたH形試験体を作成し、23℃50%RH環境下において7日間、50℃環境下において7日間、さらに90℃環境下において14日間養生した。その後23℃50%RH環境下で24時間静置させた。その時の厚み(約12.00mm)を初期とした。次に23℃50%RH環境下において所定の治具を使用し、200%伸張(約24.00mm)させた状態で24時間放置した。24時間後、治具を取り外し1時間静置後、厚みを測定し、下記式を用いて復元性を得た。
復元性(%)=(伸張後の厚み−解除後の厚み)/初期の厚み×100
シーリング材養生条件:23℃50%RH条件下において7日間
塗料養生条件:23℃50%RH条件下において7日間
評価方法:50℃乾燥機において7日間加熱促進後、黒色珪砂を塗料にふりかけ、砂の付着度により汚染の有無を目視により確認した。全ての塗料に対して汚染が全く見られない場合は○、1つでも汚染が見られる場合は×として評価した。
塗料;ビルデック:溶剤系アクリル、大日本塗料(株)製
ビニローゼ:溶剤系塩化ビニル、大日本塗料(株)製
