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).

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

Acrylic Adhesive Activators


Activators are required for no-mix acrylic structural adhesives to create adhesion.
Certificates with a traceable lot number and product shelf life are available for these products. Download certificates from ACTIVITY after your order ships.
Heavy Duty Light-Activated Coatings for Electronics


Thinner than potting compounds, these coatings flow easily into small spaces between electrical components. They require an ultraviolet curing lamp to reach full strength. Use them to secure and insulate hardware on printed circuit boards.
Syringe coatings require a gun (sold separately) to dispense.
