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

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

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

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

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

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

Thinner than non-sagging sealants, this sealant flows easily into cracks and has a smooth finish.

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

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

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

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

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

These sealants don't degrade in sunlight.

Press this pliable rope into place to hold glass in window frames and seal leaks.

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

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

The textured finish matches concrete surfaces.

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

Seal roof openings around pipes, vents, and chimneys.

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

For invisible bond lines, these adhesives dry clear.

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

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

Even when used under water, these adhesives maintain their strength.

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

No need to mix these acrylics—apply adhesive to one surface and activator to the other, then bring surfaces together to bond.

The 3M VHB adhesive on these rolls offers a strong hold that can replace rivets, spot welds, and other permanent fasteners.

This putty-like glue cures into a pliable rubber. Use it to repair seals and cracks, or mold it into hooks and bumpers.

Pull off a small piece of putty and stick lightweight objects to a surface.

For easy positioning, these adhesives begin to harden only when exposed to light.

Invisibly bond glass and transparent plastics.

When heated, these glue sticks melt and quickly begin to harden. Use them to seal packaging and form other low- to medium-strength bonds.

An alternative to solder, these flexible, silver-filled adhesives accommodate joint movement. Use them to bond electrical components and repair circuits.

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

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.

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

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.

These gasket makers come in a tube.

Use cartridges with a standard caulk gun for quick and easy dispensing.

Dispense a uniform bead when you press the nozzle.
