    • Adhesive/adherend systems of this invention comprise a siloxane-modified adhesive component and a siloxane-modified adherend component. The siloxane-modified adhesive component is prepared by combining an epoxy resin with an organosilane ingredient, a polysiloxane resin, an amine hardener, an organometallic catalyst, a base catalyst, and any thickener and extender pigment. The siloxane-modified adherend component is prepared using a polysiloxane resin and may also contain other resins such epoxy, phenolic, polyester, vinyl ester, polyurethane, polyamide, melamine, furan, acrylate, thermoplastic polyvinyl chloride, polyethylene, polycarbonate, ABS, polystyrene, ethylene vinyl acetate, polyvinyl acetate, polyamide, and polypropylene resins. When placed into contact with one another, the siloxane groups in the siloxane-modified adhesive and siloxane-modified adherend components form Si-O-Si bonds between themselves to form an attachment force that both occurs at ambient temperature within a reasonable amount of time, and that is greater than otherwise possible using adhesive/adherend systems having unmodified adhesive and/or adherend components.
    • 本发明的粘合剂/粘附体系包含硅氧烷改性的粘合剂组分和硅氧烷改性的粘合剂组分。 通过将环氧树脂与有机硅烷成分,聚硅氧烷树脂,胺硬化剂,有机金属催化剂,碱催化剂和任何增稠剂和增量颜料组合而制备硅氧烷改性的粘合剂组分。 使用聚硅氧烷树脂制备硅氧烷改性的被粘物成分,还可以含有环氧树脂,酚醛树脂,聚酯,乙烯基酯,聚氨酯,聚酰胺,三聚氰胺,呋喃,丙烯酸酯,热塑性聚氯乙烯,聚乙烯,聚碳酸酯,ABS,聚苯乙烯, 乙烯醋酸乙烯酯,聚乙酸乙烯酯,聚酰胺和聚丙烯树脂。 当彼此接触时,硅氧烷改性的粘合剂中的硅氧烷基团和硅氧烷改性的被粘物组分在它们之间形成Si-O-Si键,以形成两者都在合适的时间内在环境温度下发生的附着力, 并且使用具有未改性粘合剂和/或被粘物组分的粘合剂/被粘物体系大于另外可能的情况。
