Abstract:
A method for bonding a component to a surface comprising the steps of:filling a seam disposed between the component and the surface with a cement to produce a cemented location, the cement comprising an epoxy-based cement comprising from about 20 to about 70 percent by weight of a cationically hardenable solvent-free epoxy comprising a conversion product of a cycloaliphatic diepoxy and an aromatic compound that comprises OH-groups, from about 10 to about 60 percent by weight of a compound comprising multiple hydroxyl groups, from about 0.02 to about 2 percent by weight of a cationic photoinitiator, from about 0.02 to about 2 percent by weight of a latent thermal initiator comprising a thiolanium salt, and from about 20 to 60 percent by volume of a filler with a maximum particle size of 50 .mu.m, and wherein the cemented location comprises a thermoplastic surface;aligning the component on the surface;irradiating the cement with electromagnetic radiation in the UV/VIS region thereby fixing the cemented location;heating the cemented location to thermally harden the cemented location.
