Fasto UV98 – UV Curable Adhesive for Glass Bonding

Fasto UV98 is a single-component, very low viscosity, UV-curable adhesive designed to deliver clear, flexible, and aesthetically clean bonds when exposed to UV light. It is specially formulated to provide medium-strength bonding to glass, making it ideal for decorative and precision glass applications where transparency and non-yellowing performance are critical.

Its low viscosity allows the adhesive to wick easily into pre-assembled joints, ensuring clean bonding without visible adhesive lines.

    Cures rapidly on exposure to UV radiation.
  • Very Low Viscosity (~57 cPs)
    Excellent capillary action for pre-assembled parts.
  • Crystal Clear & Non-Yellowing
    Maintains optical clarity over time.
  • Medium Strength Glass Bonding
    Optimized for decorative and furniture-grade glass joints.
  • Flexible Bond After Cure
    Absorbs minor stresses and vibrations.
  • Fast Fixture Time
    Achieves handling strength in less than 5 seconds under UV light.

Benefits

Surface Preparation

  • Ensure bonding surfaces are clean, dry, and free from oil, grease, dust, and contaminants.
  • UV98 is sensitive to UV light, so avoid unnecessary light exposure before application.

Application Method

  1. Apply Fasto UV98 to one bonding surface only.
  2. Assemble and align the components accurately.
  3. Expose the bonded area to UV light (310 nm or above) to initiate curing.
  4. Ensure complete exposure of the bond line for uniform curing.

Curing Guidelines

  • Fixture time:
    • <5 seconds @ 10 mW/cm²
    • <3 seconds @ 30 mW/cm²
  • Typical depth of cure: up to 2 mm
    (Deeper cure possible with high-intensity lamps and longer exposure)
  • Maximum recommended bond depth: ~3 mm

Additional Notes

  • UV lamps are recommended for controlled, repeatable curing.
  • Sunlight can cure the adhesive, but results may vary.
  • Use UV-opaque (black) tubing for dispensing systems to prevent premature curing.
