INVISISIL™ UV Delay Cure Silicones

INVISISIL™ UV Delay Cure Silicones for Optical Bonding

INVISISIL UV Delay Cure silicones are two-part adhesives that activate with UV light. The delayed curing feature allows bonding in shadowed areas where UV light cannot reach or enables precise component alignment before final curing. Curing delay times can be adjusted by varying UV intensity and exposure duration. Final curing can be rapidly achieved with heat or more slowly at room temperature.

Key Features
  • UV curing of shadowed areas  
  • Delayed curing allows for component alignment 
  • Adjustable curing time based on UV settings  
  • Optically clear (refractive index ~1.4)  
  • Non-yellowing formulation
Typical Applications
  • Bonding non-light-transmitting components  
  • Assemblies that require component alignment before final cure
