What is UV Curing?
UV adhesives remain liquid until exposed to specific wavelengths of ultraviolet light. Once exposed, they harden (polymerize) in mere seconds.
Key Benefits
- “Cure on Command”: You have infinite time to align parts. The glue won’t dry until you shine the light.
- Speed: Full cure in 1-10 seconds allows for immediate handling and quality control testing.
- Clarity: Many UV adhesives cure crystal clear, making them ideal for glass and display bonding.
Limitations
The light must reach the adhesive. This means at least one substrate must be transparent to UV light. Shadows are the enemy of UV curing.
