Light Activated Adhesive

DELO Katiobond & DELO Photobond Key Features

  • Light activated adhesive range
  • For bonding non-transparent parts
  • Fast-curing adhesives, resulting in short cycle-times
  • Excellent chemical resistance
  • One-part adhesives, ideal for manual or automated processing
  • Excellent performance over wide temperature range

Light Activated Adhesive: Under normal circumstances, it is not possible to bond non-transparent parts together with traditional light-cured adhesives, as 100% of the adhesive cannot be illuminated, leaving un-cured adhesive between the parts being bonded. DELO’s light-activated adhesives are the solution. Simply apply the adhesive onto the base substrate; activate with high-intensity light for a short period of time (< 20s); within the resulting open-time of the adhesive (i.e. before a skin forms on the adhesive surface), place the other substrate onto the adhesive. Full cure is achieved after 24 hours.

To reduce the waiting time, heat can be applied to accelerate the cure. Alternatively, if there is a fillet around the edge of the joint, illuminating this fillet with high-intensity light achieves handling strength within seconds.

Activated with visible (400-550nm) light, DELO KATIOBOND and DELO PHOTOBOND are one-part adhesives that cure at room temperature. The light activated adhesives are especially suitable for bonding, sealing and potting applications.

They also have good temperature resistance, up to 180°C, and excellent chemical resistance, making them ideal for automotive and harsh environment use. Cured products exhibit low shrinkage, resulting in low stress on delicate devices. Low water absorption and very low ionic content make them ideal for electronic applications.
