クイック・ナイフ接着(QKA)をSAEJ1720法に従って行った。6.3mm(幅)×6.3mm(高さ)×100mm(長さ)大のシーラントビードを試験する被着体上に塗布し、このアセンブリを特定の時間、23℃、50パーセントの相対湿度条件下で硬化させる。次に、ビード端部を180度角で引き戻しながら、硬化したビードを45度角で試験する被着体までカミソリの刃で切断する。刻み目は塗装された表面上で3mmごとに付ける。接着の程度は、接着破壊(AF)及び/又は凝集破壊(CF)で評価する。AFの場合、硬化したビードは試験する被着体表面から分離されるが、CFにおいては、分離はシーラント接着剤内部で切断及び引張りの結果として生ずる。試験した被着体はそのままで使用するか、プライマーによる下塗りを行って、又はイソプロパノール(IPA)若しくはナフサ(NP)であらかじめ拭って(pre-wipe)使用してもよい。
約6.3mm幅、8mm高の接着剤ビードを、ガラス被着体(25mm×75mm)の全幅に沿って、下塗りされた端部より約6mmから12mm塗布する。該ガラスを、ダウ・ケミカル社より入手可能なBETASEALTM43518プライマーを含む布による塗布、清浄な布によるBETASEALTM43518プライマーの拭い去り、及びその後のダウ・ケミカル社のダウ自動車事業部門(Dow Automotive business unit)より入手可能なBETASEALTM43520Aプライマーの該ガラスへの塗布によって処理する。塗装された被着体をすぐに接着剤上に設置し、試料を23℃及び50パーセント相対湿度の状況下、3ないし7日間硬化させる。次に、この試料を、初期重ね剪断強度のためにすぐに、又はさらなる環境曝露の後に、インストロン試験機を用いて毎分1インチ(毎分2.5cm)の速度で引張った。特に記載されない限り、条件ごとに少なくとも3個の重ね剪断試料からなる一群を試験し、平均をとる。試料切断時の負荷を記録する。耐候性試験の為、試料を最初に23℃、50パーセント相対湿度の下で7日間硬化させ、その後ウェザロメーター(Weather-O-Meter)(WOM)チェンバー中に入れる。該試験チェンバーには、特に記載されない限りSAEJ1885条件が用いられる。
ここに記載されるプレポリマーの粘度はBhatの米国特許第5,922,809号、第12段、38〜49行(参照によりこの明細書に組み入れられたものとする)に開示されている手順に従って決定される。ここに記載される接着剤の粘度はプレスフロー(press flow)(PF)を使用して決定する。プレスフローは特に記載されない限り80psi(552kPa)の圧力で0.157インチ(4mm)の開口部を20グラムの接着剤が通過する時間である。接着剤の3日間54℃熱老化進行(3 day-54℃ heat age growth)は、接着剤の3日間54℃熱処理後に増加したプレスフローを接着剤の最初のプレスフローで割ったものとして定義される。
不粘着時間を下記試験手順に従って測定する。150mm長、6mm径の接着剤ビードを23℃、50パーセント相対湿度の下で剥離紙上に置き、タイマーを始動させる。次にポリエチレンフィルムを用いて該ビードをそっと触り、ビードが不粘着性となってポリエチレンフィルムがビードとの接触後も清浄であるようになるまでに経過した時間を記録する。
前記接着剤を2枚の剥離紙の間に注入し、その後3mm厚の円形にプレスする。23℃、50パーセント相対湿度の下、接着剤を7日間硬化させた後、ダイC(die C)を用いたASTM D412法に従い、毎分20インチで引張強度及び伸びを試験する。引張強度はポンド/平方インチ (psi) 単位で記録し、伸びは百分率で記録する。
