ROOM TEMPERATURE CURABLE ADHESIVE
PROBLEM TO BE SOLVED: To provide a room temperature curable adhesive without generating solvent odor such as a solvent-based adhesive, having excellent adhesive power, excellent in coating property at low viscosity and capable of easily being constructed by using general purpose tools such as a combing trowel.SOLUTION: The room temperature curable adhesive contains 100 pts.mass of a polyoxyalkylene-based polymer having crosslinkable silyl group, number average molecular weight of 15000 to 50000, molecular weight distribution (weight average molecular weight (Mw)/number average molecular weight (Mn)) of 1.3 or less, 30 to 300 pts.mass of settleable calcium carbonate having BET specific surface area of 19 m/g or more and 1 to 10 pts.mass of an aminosilane coupling agent.SELECTED DRAWING: Figure 1
【課題】 本発明は、溶剤系接着剤のような溶剤臭を発せず、優れた接着力を有すると共に、低粘度で塗工性に優れており、くしめゴテなどの汎用の器具を用いて容易に施工できる室温硬化性接着剤を提供する。【解決手段】 本発明の室温硬化性接着剤は、架橋性シリル基を有し且つ数平均分子量が１５０００〜５００００、分子量分布（重量平均分子量（Ｍｗ）／数平均分子量（Ｍｎ））が１．３以下であるポリオキシアルキレン系重合体１００質量部と、ＢＥＴ比表面積が１９ｍ2／ｇ以上の沈降性炭酸カルシウム３０〜３００質量部と、アミノシランカップリング剤１〜１０質量部とを含有していることを特徴とする。【選択図】 図１
