Optical glass bonding

Find out all there is to know about optical bonding

Assembly of glass / other materials with a UV light / visible light curing UV adhesive

Optical bonding refers to the use of UV adhesives which set under UV rays and/or visible light.

Optical bonding is mainly used in the assembly of glass with different materials such as iron, metal, wood or plastic. Its advances now offer many advantages to production technologies.

UV adhesive is essentially composed of acrylate resin or epoxy resin. UV adhesive is an excellent solution for applications which require high mechanical strength and ultra-fast bonding; this is why optical bonding is used for decorative glass, optical glass or electronics assemblies.

KEOL mainly uses two ranges of photo-polymerization adhesives: the first is acrylate resin-based and the second is epoxy resin-based.


Acrylate resin-based UV adhesive

This solvent-free one-part adhesive polymerizes very quickly by UV or visible light curing until the final strength is achieved. It has good resistance to ageing and humidity as well as good adhesion on a variety of surfaces. This is especially beneficial to applications which require optical transparency and quick, high performance bonding.

Epoxy resin-based UV adhesive

This solvent-free one-part adhesive sets in a few seconds under UV and/or visible light depending on the type of adhesive. Photo-hardening UV adhesive is activated over short curing times of between 2 and 8 seconds. The adhesive remains liquid for the first 10 to 30 seconds after it has been activated to enable a second component to be added if necessary.
