About Structural Adhesives

These adhesives stay pliable for flexible bonds that resist cracking. For easy positioning, they begin to harden only when exposed to light.

1700A257 and 2454N1 fluoresce under UV light for easy inspection.

Use adhesives in syringes with a dispensing gun with plunger (sold separately).

Light-Activated Instant-Bond Adhesives

For easy positioning, these adhesives begin to harden only when exposed to light.

Thick liquids fill large gaps and won't drip on vertical surfaces. Thin liquids flow to fill small gaps between close-fitting parts.

352 can also be cured with an activator (sold separately).

Use adhesives in syringes with a dispensing gun with plunger (sold separately).

Moisture-Resistant Light-Activated Instant-Bond Adhesives

Moisture, humidity, and immersion in water won't degrade the bond of these adhesives. For easy positioning, they begin to harden only when exposed to light. Use a dispensing gun with plunger (sold separately) to dispense adhesive.
