Adhesives for assembling components of inert material

A method for bonding at least two parts of which one is at least an impregnated or impermeabilized material, comprising the following steps:

• applying to one part an adhesive formulation for bonding two materials at least one of which being an impregnated or impermeabilized material, comprising
• 40 to 80 wt.-% of an epoxy monomer;
• and
• 15 to 30 wt.-% of an oxetane monomer;
• and
• 0.1 to 10 wt.-% of an adhesion promotor;
• and
• 0.1 to 5 wt.-% of a sensitizer;
• and
• 1 to 10 wt.-% of a radiation and temperature activatable photoinitiator or a mixture of a photoinitiator and a thermal initiator,
• and further comprising a fluorurated epoxy monomer being 3-Perfluorooctyl-1,2-propenoxide;
• placing another part to be bond on the one part;
• exposing the parts to UV light radiation;
• and
• heat treating of the part.
