UV light curing and bonding
Types of UV light curing materials
- UV structural adhesives for bonding glass, ceramics, ferrites, plastics and metals
- UV hot melt pressure sensitive adhesives
- UV glob tops, chip coats and conformal coatings
- UV potting compounds and encapsulants
- UV paints, inks and coatings
- UV hardening resin/glassfibre composite materials
General benefits of UV light curing
- Enhanced material properties
- On demand cure – only cures on exposure to UV light
- Rapid curing times – in some cases instantaneous, allowing immediate further processing
- No solvents, 100% solids – no environmental pollution due to solvent evaporation
- Single component – ready to use systems – no mixing, no waste, no disposal of waste, no cleaning of mixing containers, no problems with pot life of mixed materials
- Minimal space requirements and relatively low capital expenditure for UV light equipment
- Automated handling, dispensing and UV curing can be employed to improve production efficiency
- Saving of raw materials and energy – no wasted solvent or energy required to produce evaporation of solvent. UV lamps are more efficient than thermal ovens
- No heat required – thus low thermal stressing of substrate materials
- Readily adapted into existing processes
