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.

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

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

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

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

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

The textured finish matches concrete surfaces.

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

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

Assortments include eight different epoxies in 0.1-oz. packets to handle a variety of small jobs.

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

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

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

Fasten hard-to-bond plastics, such as polypropylene and polyethylene, with these epoxies.

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

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

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

Accommodate joint movement with these adhesives that remain pliable when cured.

Use these thick gels, also known as super glue, on vertical surfaces or to fill gaps between parts.

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

Splice rubber O-rings and other gaskets with this chemical resistant adhesive.

Form bonds with twice the strength of our other spray adhesives.

Temporarily stabilize objects on flat surfaces with this clear, reusable adhesive.

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

Apply this glue like tape for a no-mess alternative to liquid adhesives, hot melts, and staples. Also known as adhesive transfer tape.

Apply these adhesives on two surfaces, air dry, and then bring together to bond.

This cement has excellent temperature resistance for sealing insulation joints on ovens and furnaces.

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.

These coatings are often used on castings, dies, and mirrors to prevent rust, abrasion, and moisture penetration.

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

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

Clear enough to read through, this coating allows optimal light transmission for use with LEDs, solar cells, and fiber optics.

Used to insulate, create grips, and color-code components, these coatings resist high temperatures, light abrasion, and corrosion.

Able to withstand temperatures of up to 2000° F, these coatings absorb heat and release it later. Use them to improve the thermal efficiency of heaters, furnaces, and ovens to reduce energy costs. Also known as high-emissivity coatings.

Longer-lasting than antislip tape, these coatings contain grit to provide traction. They’re good for areas with pedestrian traffic.

Commonly used by electronics manufacturers and research labs, apply these coatings to floors and walls to protect equipment from static electricity buildup.

Made of rubber and iron oxide, these sheets can be cut with scissors to create custom-shaped nonmetallic, nonmagnetic surface that magnets will stick to.

These thin primers penetrate deeply into concrete floors to create a hard surface that can then be coated with any urethane or epoxy coating.

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

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.

Knead the epoxy-coated patch and resin together to make repairs to pipes, tanks, drums, and containers in the field.

Mix these two-part epoxy surface fillers to create a strong repair in wet environments or underwater.

Also known as sloshing compounds, these surface fillers bond to rough, rusty surfaces in fuel tanks to repair leaks and prevent further corrosion.

Stop active leaks of up to 50 gallons per minute in concrete, brick, and stone. These crack fillers begin to harden within seconds to create a permanent fix that won't shrink.

Mix this two-part epoxy—a resin-aggregate blend and a pigmented hardener—to create a grout that resists chemicals and doesn't require sealing. Use on ceramic, concrete, and stone floor and wall tiles.

Remove silicone, foam sealants, caulk, wet or dry latex-based foams, and construction adhesives.
