About Sealant Flexibility

Sealants

Puncture-Resistant Sealants

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

All-Weather Application Sealants

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

Optically Clear All-Weather Application Sealants

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

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.

Noncorrosive Silicone Sealants

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

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.

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.

Caulk

Create-a-Color Caulk

Mix a small amount of water-based paint with this caulk to match the color of your surface.

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.

Vacuum Leak Sealants

Also known as Torr Seal, this sealant forms a rigid bond that seals leaks on vacuum systems or components.

Self-Leveling Oil- and Fuel-Resistant Sealants

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

Oil- and Fuel-Resistant Sealants

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

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.

Chemical-Resistant Sealants

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

Self-Leveling Chemical-Resistant Sealants

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

Concrete Joint Sealants

Seal joints and gaps in concrete.

Textured Concrete Joint Sealants

$Textured Concrete Joint Sealants$

The textured finish matches concrete surfaces.

Self-Leveling 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.

High-Temperature Concrete Joint Sealants

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

Self-Leveling All-Weather
Application Concrete Joint Sealants

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

All-Weather Application Concrete Joint Sealants

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

UV-Resistant Glass Sealants

These sealants don't degrade in sunlight.

Roof Joint Sealants

Self-Leveling Roof Joint Sealants

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

Roof Joint Sealants

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

All-Weather Application Roof Joint Sealants

Fix roof leaks in cold and wet conditions. These sealants can even be applied underwater.

Roof Pipe Sealing Kits

Seal roof openings around pipes, vents, and chimneys.

Structural Adhesives

Quick-Set Epoxy Structural Adhesives

For quick repairs, these epoxies begin to harden in 6 minutes or less.

Metal-Reinforced Epoxy Structural Adhesives

These machinable epoxies are mixed with steel, but won’t rust, so they can be used to repair cracks and threaded holes.

Epoxy Structural Adhesives

Epoxies are the strongest and most weather- and chemical-resistant structural adhesives. They work especially well on metals.

Slow-Set Epoxy Structural Adhesives

To allow time to adjust and position parts, these epoxies remain workable for at least 90 minutes.

Epoxy Structural Adhesives for Harsh Environments

With excellent resistance to corrosive chemicals and salt water, these epoxies work in tough conditions.

Toughened Epoxy Structural Adhesives

Toughened adhesives are blended with rubber particles for better impact resistance than standard epoxies. They form flexible, resilient bonds.

Urethane Structural Adhesives

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

High-Strength Urethane Structural Adhesives

With high shear strength and peel strength, these form the strongest bonds of our urethane adhesives.

Acrylic Structural Adhesives

Acrylics bond to the widest range of materials, especially plastics, and require the least amount of surface preparation.

Toughened Acrylic Structural Adhesives

Toughened adhesives are blended with rubber particles for better impact resistance than standard acrylics. They form resilient bonds.

Construction Adhesives for Dissimilar Materials

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