About Sealant Flexibility

Epoxy Potting Compounds

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.

Optically Clear Epoxy Potting Compounds

Clear enough to read through, these UV-resistant potting compounds allow optimal light transmission for use with LEDs, solar cells, and fiber optics.

Two-Part Silicone Potting Compounds

Optically Clear Two-Part Silicone Potting Compounds

Clear enough to read through, this UV-resistant potting compound allows optimal light transmission for use with LEDs, solar cells, and fiber optics.

Ready-to-Use Silicone Potting Compounds

No mixing required—these potting compounds come ready to apply.

Urethane Potting Compounds

Urethanes withstand a wide range of temperatures and are the best choice for cold-temperature applications. They have excellent flexibility, good chemical and moisture resistance, and provide good electrical insulation.

High-Purity Urethane Potting Compounds

This potting compound is formulated for use in sensitive applications such as manufacturing semiconductors.

Adjustable-Flexibility Heat-Transfer Potting Compounds

Change the mix ratio of these heat-transfer potting compounds to achieve the right hardness for your application.

Heat-Transfer Potting Compounds

Formulated to draw heat away from sensitive electronic components, these potting compounds have higher thermal conductivity than standard potting compounds.

Heavy Duty Coatings for Electronics

Heavy Duty Heat-Transfer Coatings for Electronics

This thermally conductive coating keeps electrical components cool by dissipating heat.

Heavy Duty Coatings for Electronics

Thinner than potting compounds, these rigid and wear-resistant coatings flow easily into small spaces between electrical components. Use them to secure and insulate hardware on printed circuit boards.

Heavy Duty High-Purity Coatings for Electronics

This coating is formulated for use in sensitive applications such as manufacturing semiconductors.

Heavy Duty High-Purity Light-Activated
Coatings for Electronics

This coating is formulated for use in sensitive applications such as manufacturing semiconductors.

Sealants

Self-Leveling Silicone Sealants

Thinner than non-sagging sealants, these flow easily into cracks and have a smooth finish.

Self-Leveling Silicone Sealants
with Material Certification

These sealants include a material certificate with traceable lot number, test report, and product shelf life.

Silicone Sealants

Made from silicone, these sealants are RTV (room-temperature vulcanizing).

Silicone Sealants with Material Certification

These sealants include a material certificate with traceable lot number, test report, and product shelf life.

Mildew-Resistant Silicone Sealants

Resistant to mold and mildew, these sealants are well suited to high-humidity environments.

Noncorrosive Silicone Sealants

Also known as neutral-cure sealants, these won't discolor copper, brass, and concrete.

Noncorrosive Silicone Sealants
with Material Certification

This sealant includes a material certificate with traceable lot number, test report, and product shelf life.

Structural Silicone Sealants

Metal- and X-Ray-Detectable Structural
Noncorrosive Silicone Sealants

With chemical and metal additives that are picked up by X-ray machines and metal detectors, these sealants are designed to help you comply with Hazard Analysis and Critical Control Point (HACCP) programs in food-processing facilities.

Structural Silicone Sealants with Material Certification

These sealants include a material certificate with traceable lot number, test report, and product shelf life.

Structural Noncorrosive Silicone Sealants

Also known as neutral cure, this sealant won't discolor copper, brass, plastic, and concrete.

Glass Sealants

Structural Glass Sealants

Make seals that support glass under heavy loads in equipment and buildings.

UV-Resistant Glass Sealants

These sealants don't degrade in sunlight.

Adhesives

Mixer Nozzles for Two-Part Adhesive Cartridges

To simultaneously mix and dispense two-part adhesives, attach these mixer nozzles to a dual cartridge.

Insulating Adhesives for Electronics

Tack wires to coil forms or secure and insulate hardware on printed circuit boards. These adhesives require an accelerator.
