Epoxy Potting Compounds


Encase electronic assemblies in a layer of epoxy for protection from dust, chemicals, moisture, mechanical shock, and vibration. The strongest of the potting compounds, epoxies are rigid and wear resistant. They have excellent chemical and moisture resistance, withstand a wide range of temperatures, and provide excellent electrical insulation. All require a mixer nozzle and gun to dispense.
3M DP460EG and DP4XLEG also require a plunger to dispense.
Loctite® 3336™, ES1001™, ES1902™, and ES2500™ come with a mixer nozzle.

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.
The size listed is the combined total of the two parts.

Mixer Nozzles for Two-Part Adhesive Cartridges



To simultaneously mix and dispense two-part adhesives, attach these mixer nozzles to a dual cartridge. Mixing elements help combine the two parts of an adhesive as it flows through the nozzle. A short nozzle with many mixing elements combines adhesive while minimizing the adhesive left in the nozzle after dispensing. Choose a nozzle that matches the connection type, size, and mix ratio of your adhesive cartridge.
A step tip allows you to trim the opening to the diameter you need.

Conductive Surface Fillers for Electronics



A high silver content allows these surface fillers to conduct electricity and heat. Use them to fill gaps and rebuild missing material on electrical connections or to assemble new components. Product regulations restrict sales to the listed jurisdictions/areas.
Surface fillers in one-time-use packets and jars come as two parts. The size listed is the combined total of the two parts.
Surface filler in a pen dispenses as a thin, ready-to-use liquid that fills in pitting and small gaps. It’s often used on circuit boards to fix components or to prototype new systems.
Volume resistivity and surface resistivity measure how well a material opposes the flow of electricity. The lower the rating, the more electricity it conducts.
Thermal conductivity measures a material’s ability to transfer heat. The higher the rating, the more heat it transfers.
