各組成物の25℃における動粘度をJIS Z 8803:2011に準拠したキャノン-フェンスケ粘度計を用いた方法にて、測定した。
[引張強さ・切断時伸び]
各組成物を、深さ2mm、幅120mm、及び長さ170mmの金型に流し込み、窒素置換した容器に入れ、該組成物に365nmにピークトップを持つUV-LED(日亜化学工業(株)社製)2灯を備えるコンベア炉内(照度:3,000mW/cm2)で0.2秒間紫外線を照射し(エネルギー量(積算照射量):600mJ/cm2)、厚さ2mmのシート状硬化物を得た。該シート状硬化物の引張強さ及び切断時伸びを、JIS K 6249:2003に準拠した方法にて測定した。
各組成物を深さ1mm、幅20mm、及び長さ20mmの金型に流し込み、大気中、365nmにピークトップを持つUV-LED(日亜化学工業(株)社製)を照度10mW/cm2で照射しながら、各組成物の指触試験を行った。組成物の表面に糸引きが観察されなくなるまでに要した時間を測定した。
各組成物を深さ1mm、幅120mm、及び長さ170mmの金型に流し込み、該組成物に365nmにピークトップを持つUV-LED2灯を備えるコンベア炉内(照度:3,000mW/cm2)で0.2秒間紫外線を照射し(エネルギー量(積算照射量):600mJ/cm2)、厚さ1mmの硬化物シートを得た。該硬化物シートの水蒸気透過率を、水蒸気透過度計(Lyssy、L80-5000;Systech Instruments社製)にて測定した。
これに対し、本発明の放射線硬化性有機ケイ素樹脂組成物は、シロキサン結合数を制限した(メタ)アクリロイル基含有有機ケイ素化合物を含むことにより、水蒸気透過性が低く、ガスバリア性に優れる硬化物を与える。さらに、(メタ)アクリロイル基を2個以上有する化合物を重合させるため、引っ張り強さ、切断時伸び等、強度が良好な硬化物を与える。また、本発明の放射線硬化性有機ケイ素樹脂組成物は低粘度であるため、スピンコートやインクジェットなどでも塗工できるほどの作業性に優れる。さらには、最も好ましい態様においては光重合開始剤の配合量を調製することにより、放射線照射にて大気中で速やかに硬化することができる。
