Flexible Light-Activated Instant-Bond 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.

Light-Activated Epoxy Potting Compounds
Handle potted items within minutes—these potting compounds dry quickly when exposed to UV light. For added strength and durability, cure them with heat. Since they’re epoxy, they won’t break down from chemicals or moisture. They’re also excellent electrical insulators and withstand a wide range of temperatures. Use them to shield components from dust, moisture, chemicals, mechanical shock, and vibration. You need a mixer nozzle (not included) and a gun and plunger (both sold separately) to dispense. The nozzle lets you apply these compounds precisely.
For maximum effectiveness, these compounds need to be heat cured after they’re cured with UV light. Overall dry time includes heat curing at 149° F.

Light-Activated Silicone Potting Compounds
These compounds dry quickly when exposed to UV light allowing you to handle the potted items sooner. Made of silicone, they’re softer and more flexible than epoxy or urethane compounds, so they’re better at protecting against shocks and vibration. They also withstand a wider range of temperatures, so they’re often used with electronics that heat and cool rapidly. These compounds are excellent electrical insulators, and they’ll shield your components from moisture and dust. However, they don’t hold up well to abrasion or chemicals. The tapered nozzle lets you apply them precisely.
