About Sealant Flexibility

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.

Self-Leveling Silicone Sealants
with Material Certification

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

Self-Leveling Silicone Sealants

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

Low-Outgassing Silicone Sealants

Compliant with ASTM E-595, these sealants produce almost no volatile materials in a vacuum.

Noncorrosive Silicone Sealants
with Material Certification

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

Noncorrosive Silicone Sealants

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

All-Weather Application Sealants

Apply these sealants in cold temperatures, on wet surfaces, and even through running water.

Optically Clear Sealants

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

Sealants

Puncture-Resistant Sealants

A combination of hardness and surface tension makes these sealants resistant to punctures, cuts, and abrasion.

Caulking Tape

Press this adhesive-backed plastic tape into place for an immediate light-duty seal.

Structural Silicone Sealants

Made from silicone, these sealants are RTV (room-temperature vulcanizing). They combine the mechanical strength of an adhesive with excellent sealing properties and high flexibility.

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.

All-Weather Application Structural Sealants

Apply these sealants in cold temperatures, on wet surfaces, and even through running water.

Structural Sealants

These structural sealants combine the mechanical strength of an adhesive with excellent sealing properties and high flexibility.

Vacuum Leak Sealants

Seal leaks on vacuum systems and components.

Chemical-Resistant Sealants

Self-Leveling Chemical-Resistant Sealants

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

Chemical-Resistant Sealants

Designed to withstand extreme environments, these fluoroelastomer sealants have excellent resistance to harsh chemicals. They’re non-sagging, so they won't drip from vertical and overhead surfaces.

Submersible Sealants

These sealants are marine grade, so they stand up to water, corrosion from salt spray, mildew, and UV light.

Structural Submersible Sealants

The strongest submersible sealants we offer, these combine the mechanical strength of an adhesive with excellent sealing properties and high flexibility.

Oil- and Fuel-Resistant Sealants

Structural Oil- and Fuel-Resistant Sealants

Impervious to the swelling effects of oil, fuel, and solvents, use these high-strength sealants to assemble and repair fuel systems and tanks.

Oil-Resistant Sealants

Make tough, flexible, oil-resistant seals.

Oil- and Fuel-Resistant Sealants

These non-sagging sealants will not drip while hardening on vertical and overhead surfaces.

Self-Leveling Oil- and Fuel-Resistant Sealants

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

Concrete Joint Sealants

High-Temperature Concrete Joint Sealants

Designed for use on ovens and kilns, these sealants form a durable, rock-hard seal after firing.

All-Weather Application Concrete Joint Sealants

These non-sagging sealants will not drip while hardening on vertical and overhead surfaces.

Self-Leveling All-Weather
Application Concrete Joint Sealants

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

High-Strength Self-Leveling Concrete Joint Sealants

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

High-Strength Concrete Joint Sealants

These non-sagging sealants will not drip while hardening on vertical and overhead surfaces.

Roof Joint Sealants

These sealants are non-sagging, so they won't drip from vertical and overhead surfaces.

Self-Leveling Roof Joint Sealants

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

Adhesives

Urethane Structural Adhesives

Urethane adhesives are the most flexible, so they bond dissimilar materials and damp vibration.

Construction Adhesives for Dissimilar Materials

Bond glass and stone to drywall, treated lumber, and subfloors.

Coatings for Electronics

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.

Light-Activated Silicone Potting Compounds

Pot multiple electronics in a flash—these compounds don’t require mixing and they cure within seconds under UV light.

Ready-to-Use Silicone Potting Compounds

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

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.

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

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.
