UV Adhesives
What are UV adhesives?
UV adhesives are light-sensitive adhesives that cure within seconds when exposed to ultraviolet light. These one-component systems remain workable indefinitely at room temperature and polymerize only under UV light exposure through activation of photoinitiators.
Properties of UV adhesives
- Second-fast curing under UV radiation
- Unlimited processing time without UV light
- Mostly One-component system, no mixing required
- High strengths after complete curing
- Low to no solvent emissions
- Precise control of curing process
Types of UV adhesives
- Acrylates: Fast curing, high strengths
- Epoxies: UV + heat dual-curing for shadow areas
- Urethane acrylates: Flexible systems with good adhesion
- Silicones: UV-curing with high temperature resistance
- Cyanoacrylates: UV-accelerated curing for instant fixation
Wavelength ranges
- UVA (315-400 nm): Standard wavelength for most systems
- Visible light (400-500 nm): For light-sensitive substrates
- Special wavelengths: 365 nm, 405 nm depending on photoinitiator
- LED-optimized: Narrow-band for LED curing lamps
Application areas
- Electronics manufacturing: SMD assembly and chip bonding
- Medical technology: Bonding optical components
- Automotive industry: Sensor and camera bonding
- Optical industry: Lens assembly with highest precision
- Jewelry industry: Gemstone setting and repairs
Processing guidelines
- Sufficient UV intensity for complete curing
- Uniform light distribution over bonding area
- Consider layer thickness - thicker layers cure slower
- Protection from daylight during processing
- UV safety glasses for direct lamp contact
