Description
SCA社の3Kポンプ及び投与機器。
「Pol L」と表された第1のポリオール成分の以下の内容物は、表1に以下に記載されるように、空気防湿容器内で組み合わされブレンドされ保存される。又、内容物の量が表4に示される。
「IsoC」と表されたイソシアネート成分の以下の内容物は、表3に以下に記載されるように、空気防湿容器内で組み合わされブレンドされ保存される。
反応性はレオロジーによって測定された。1時間及び2時間のラップ剪断強度は、接着寸法が15×25×1.5mmの電着されたスチール基材で測定される。実験室での剪断熱硬化実験は、180秒間の加熱サイクルと、接着寸法45×15×1.5mmのDow CFK基材で実行される。成分は、実験室にてカートリッジから並びに3K塗布装置で塗布された。従って、実施例1は、(1)カートリッジで塗布されたときの性能データに対して真空下20分間遊星ミキサーにて(本発明の範囲外)、及び(2)1.24秒間自動的に塗布された材料に対して3K塗布装置の動的ミキサーにて、列挙された混合比で比較例1及び2を混合することによって調製された。3K塗布装置は、1000rpmのミキサーの回転で10ml/秒の流速で作動された。結果を表4に示す。第1及び第2のポリオール成分(それぞれPol L及びPol S)は、様々な比で使用された。
