UV bonding & assembling is a process used for glass, metal and plastic bonding as well as the assembly of printed circuit boards. The bonding process uses ultraviolet sensitive adhesives that cure upon exposure to energy from UV curing lamps.
This process is fast, flexible (there are a large range of different adhesives from rigid to versatile available), long lasting and environmentally friendly in comparison to other processes.
The process of bonding using adhesive cured by ultraviolet light is relatively new. Single component adhesives achieve their final hardness through exposure to UV light. The finished bond is highly transparent and can be very hard or elastic in consistency depending on the type of adhesive used. The advantage of these adhesives is the easy and clean application process, and high stability.
UV-curing adhesive (or light-curing adhesive) is particularly effective on glass due to its high transparency and exceptional stability, even in difficult environmental conditions such as humidity and sunlight. It is also used for bonding glass to metal as well as glass to glass.
Some examples of UV adhesive applications include display case construction, automotive headlamp assembly, novelty bonding, sign assembly, adhering light fixtures and plastic package assembly.
