Description
シリル化ポリマーより作製した製品の下塗りされていないコンクリート基材に対する接着性を向上するための試みはなされてきた。例えば、米国特許第4,810,748号は、エポキシ官能性シリコーン流動添加剤の接着性向上の用途を開示する。米国特許第5,216,057号は、ポリシロキサン油乳剤を含む、モルタル上のアクリル酸ラテックス封止剤の向上された浸水接着性を開示する。米国特許第6,602,964号は、メルカプト−およびアルキル官能基を含むの、シリル化ポリウレタン組成物の接着性向上の用途を開示する。同様に、米国特許公開番号2007/0066768号は、シランとポリシロキサンの配合物を含むシリル化ポリウレタン組成物の、浸水後のコンクリートに対する接着性の向上の用途を開示する。これらの試みは、下塗りされていないコンクリートに対する接着性にいくらかの向上を見せたものの、これらの樹脂組成物は、下塗りされていないコンクリート上の硬化組成物が7日間水に浸漬された際、接着モード破壊を受け、また低剥離強度を持つ傾向にある。
