UV Bonding

- Principle -


UV bonding is a photochemical reaction to cure adhesives using high-intensity UV-A light. Liquid formulations contain a mix of monomer and oligomer and photoinitiators. These photoinitiatiors are activated by the UV light to link monomers & oligomers together and create a corresponding network of polymers. The formulation is then almost instantly hardened in a short period of time to bond two parts together.

UV LED lighting systems in the UV-A range (365-405nm, depending on the chemistry) are widely used for optical, plastic/glass or glass/metal bonding processes thanks to great intensity and electrical efficiency. Precise, compact & innovative LED lightings often replace old, huge & energy-consuming thermal curing or mercury lamps in a wide range of industrial applications.
