About Sealant Flexibility

Sealants

Puncture-Resistant Sealants

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

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.

Noncorrosive Silicone Sealants

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

Paintable Silicone Sealants

Unlike standard silicone sealants, this silicone sealant can be painted.

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.

Noncorrosive Silicone Sealants
with Material Certification

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

Structural Sealants

These structural sealants 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 Silicone Sealants

Non-Hardening Caulk

Also known as thumb-grade caulk, this forms a non-hardening, moisture-resistant seal that remains pliable.

Caulking Tape

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

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

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.

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.

Glass Sealants

UV-Resistant Glass Sealants

These sealants don't degrade in sunlight.

Impact-Resistant
Structural Glass Sealants

Repair equipment and vehicle windows with these sealants that are rated to withstand impact within three hours of application.

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.

Sealant Primers

Prepare joints and surfaces to ensure proper sealant adhesion.

Concrete Joint Sealants
