The protective covers of machines are usually made of transparent plastics such as polycarbonate (PC) or polymethyl methacrylate (PMMA). For structural adhesive bonds between these plastics and the painted surface of the machine, the 2-component PUR adhesive technicoll 9430-1 has proven its worth. It can fill gaps, absorbs vibrations and optimizes production cycle times due to its defined curing time. Both 1- and 2-part reactive adhesives based on EP (epoxy resin), MMA (methyl methacrylate) and also PUR (polyurethane) are suitable for bonding bare metals with thermoset plastics.
Temperature-resistant 2-component adhesives based on epoxy resin achieve the strengths required for bonding metal. If the bonding process simultaneously requires fast cycle times, fast-curing MMA high-performance adhesives such as technicoll 9403 or technicoll 9411 are suitable. For large-area metal bonding, contact adhesives based on polychloroprene (CR) should be used. If the workpiece is exposed to high temperatures or moisture, an additional crosslinker is advisable. For metals that are subsequently powder coated, technicoll 9411 is an adhesive solution.
