High-Temperature Threadlocker Paste

This thick paste withstands temperatures up to 650 °F. It's easy to apply and won't drip, even from overhead fasteners. These threadlockers begin to harden once coated surfaces are threaded together and exposure to air is blocked.

Primer (sold separately) cleans the surface and decreases the time to reach full strength. It is recommended when working with aluminum, stainless steel, and titanium; black-oxide finishes, and cadmium and zinc coatings.

Threadlockers with medium locking strength require a hand tool to unthread.

Threadlockers with high locking strength require both heat and a hand tool to unthread.

Certificates with a traceable lot number and product shelf life are available for these products. Download certificates from ACTIVITY after your order ships.

Heat-Transfer Potting Compounds

Formulated to draw heat away from sensitive electronic components, these potting compounds have higher thermal conductivity than standard potting compounds. Use them to encase electronic assemblies for protection from dust, chemicals, moisture, mechanical shock, and vibration. Rigid and wear resistant, epoxies are the strongest of the potting compounds. They have excellent chemical and moisture resistance, withstand a wide range of temperatures, and provide excellent electrical insulation.

Adjustable-Flexibility Heat-Transfer Potting Compounds

Mixing required—resin and hardener come in two separate jars or in a jar and syringe and must be combined before applying. Change the mix ratio of these heat-transfer potting compounds to achieve the right hardness for your application. They're formulated to draw heat away from sensitive electronic components, so they have higher thermal conductivity than standard potting compounds. Use them to encase electronic assemblies for protection from dust, chemicals, moisture, mechanical shock, and vibration. Rigid and wear resistant, epoxies are the strongest of the potting compounds. They have excellent chemical and moisture resistance, withstand a wide range of temperatures, and provide excellent electrical insulation.

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.
