The formulations of UV-setting acrylate adhesives are similar to those discussed above, except that a photoinitiator is responsible for the curing process. Under the influence of UV radiation, the photoinitiator generates radicals that initiate the polymerization. The resin to be cured contains reactive monomers or oligomers that

are based, for example, on urethane, as well as additives and the photoinitiator. Depending on their structure, the monomers shape the specific adhesion properties. Strength and elasticity are owed to the oligomers. A typical formulation for a UV-setting acrylate adhesive contains 33% urethane acrylate, 33% isobornyl acrylate,

25% trimethyl pentane triacrylate, 5% pigment, and 4% photoinitiator.
