Beschreibung
Zusammenfassung:	A curable adhesive that is particularly well suited for use in an injection or compression molding operation. The adhesive is based on polymeric resins having carboxylic acid and acrylate ester functionality, such as grafted phenoxy resin, and further constituents such as organic carbonates, blocked isocyanates, catalysts, maleimide compounds, hydride sources, and a carrier fluid. The curable adhesives are particularly well suited for bonding liquid injectable substrates such as liquid silicone rubber, or polyamides to rigid substrates, such as aluminum, stainless steel, or glass. La présente invention concerne un adhésif durcissable qui est particulièrement bien approprié pour une utilisation dans une opération de moulage par injection ou par compression. L'adhésif est à base de résines polymères à fonction acide carboxylique et ester d'acrylate, telles qu'une résine phénoxy greffée, et contenant d'autres constituants, tels que des carbonates organiques, des isocyanates bloqués, des catalyseurs, des composés de maléimide, des sources d'hydrure et un fluide porteur. Les adhésifs durcissables sont particulièrement bien appropriés pour coller des substrats injectables liquides, tels qu'un caoutchouc de silicone liquide, ou des polyamides à des substrats rigides, tels que l'aluminium, l'acier inoxydable ou le verre.
