Description
数平均分子量が500〜3000の範囲内であるとき、特に、十分な溶解性を示し、塗膜に粘着が残ることも無い。水酸基が20〜200の範囲内にあるとき、特に、十分な溶解性を示し、塗膜に粘着が残ることも無い。主剤の構成成分として添加される数平均分子量500〜3000程度のポリカーボネート樹脂は、硬化剤の成分であるイソシアネート化合物と反応し硬化皮膜に更なる耐候性、接着力を付与する。ポリカーボネート樹脂とイソシアネート化合物を事前に反応させ、より高分子のポリカーボネートウレタンポリオールを主剤として、更に硬化剤のイソシアネート化合物と反応させる工程に比べ、適度の硬化皮膜の形成及び工程の簡略化に優れる。
主剤を構成するポリエステルポリオール樹脂として、数平均分子量約5000、水酸基価約11である(A1)ディックドライLX−71A(DIC製)、数平均分子量約6000、水酸基価約21である(A2)ベッコライトM−6180−50(DIC製)、数平均分子量約5000、水酸基価約7である(A3)テスラック2503−63(日立化成ポリマー製)、数平均分子量約13000、水酸基価約11である(A4)アロンメルトPES−375SE50(東亜合成製)、数平均分子量約20000、水酸基価約4である(A5)エリーテルXO−0276(ユニチカ製)を使用した。
原反として、50μm厚のPETフィルム(東洋紡(株)E5100)を用い、上記の各接着剤組成物を、5.0g/m2(乾燥質量)に塗装して、貼合用フィルムとして、50μm厚のPETフィルム(東洋紡(株)E5100)用い、評価用塗布サンプルを得た。評価用塗布サンプルは、40℃、72時間、エージングした後、評価に供した。
前記した評価サンプルを、引っ張り試験機(SHIMADZU社製;AGS500NG)で、スピード300mm/minで引っ張った際の強度(N/15mm、180度剥離)を測定した。初期、及び、85℃85%RH環境下の500時間、1000時間、1500時間暴露後に測定した。結果を表1−4に示す。各表中の85%は全て85%RHを示す。また、各表中の接着力の強度の単位は、全てN/15mmである。
