なお、成分(E)の使用量は、上記成分(D)の1~8質量%とすることが好ましい。

〔粘度〕
シリコーン組成物の絶対粘度は、マルコム粘度計(タイプPC-1TL)を用いて25℃で測定した。
熱伝導率は、シリコーン組成物を100psi(0.7MPa)の圧力で加圧したまま150℃で90分間硬化させた(硬化物厚さ6mm)後に、迅速熱伝導計QTM-500(京都電子工業(株)製)により25℃において測定した。
直径12.7mmの円形アルミニウム板2枚に、シリコーン組成物を挟み込み、0.7MPaにて150℃で90分間加熱を行うことにより熱抵抗測定用の試験片を作製した。なお、この試験片の熱抵抗測定はナノフラッシュ(ニッチェ社製、LFA447)を用いて実施した。
シリコーン組成物を150℃で100psi(0.7MPa)の圧力で加圧したまま90分間加熱を行い、厚み2mm、6cm四方のシート状サンプルを準備した。このサンプルの中心部を折り曲げて、表面に破断が生じた際の図1に示す角度αを記録した。角度が大きいほど柔軟性に優れているとした。
シリコーン組成物200gを容器にとり、25℃にて保存試験を行った。24時間(1日)ごとに硬化有無の確認を行い、硬化するまでの日数を調べた。硬化するまでの期間が長いほど保存性に優れているとした。
