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

For invisible bond lines, these adhesives dry clear.

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

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.

Solvents, oils, acids, and other chemicals won't degrade the bond of these adhesives.

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

For flexible bonds that resist cracking, these adhesives stay pliable.

Invisibly bond glass and transparent plastics.

Spray a thin, uniform coat of adhesive on one or both surfaces, air dry, and then bring together to form strong bonds.

Bonds reach full strength in 10 minutes.

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.

Adhere vinyl and rubber wall bases to wood, drywall, and concrete.

Prevent threaded fasteners from loosening due to shock and vibration.

Withstand demanding, high-vibration applications such as motor and pump housings with these threadlockers.

These low-friction threadlockers harden slowly, allowing ample time to smoothly adjust multiple large bolts for even clamping.

These threadlockers meet NSF/ANSI 61 for drinking water.

This thick paste withstands temperatures up to 650 °F.

These threadlockers hold securely but stay flexible, so fasteners can be adjusted, removed, or reused.

Apply these threadlockers on fasteners that are already installed—their thin consistency allows them to flow into small gaps.

Improve instant-bond adhesive performance on hard-to-bond materials.

Fill gaps up to 0.01" to secure unthreaded cylindrical metal parts such as shafts, bearings, and press-fit assemblies.

Fill gaps up to 0.02" to secure worn unthreaded cylindrical metal parts such as shafts, bearings, and press-fit assemblies.

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

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.

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

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

Often used in high-vibration applications that could cause standard thread sealants to fail, these never fully harden and remain pliable enough to self-heal and stop leaks before they start.

Prepare joints and surfaces to ensure proper sealant adhesion.

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

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

These surface fillers come in a pen for precision application. After applying, use the LED on the back of the pen to instantly cure.

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.

Pour these ready-to-use fillers in cracks up to ½" wide and ¼" deep on horizontal surfaces to make fast, light duty repairs.

Repair holes and seal gaps in roofing and gutters. These patching compounds are durable and water resistant.

Fix cracks in drywall and stop them from spreading. Place the included fabric over wall cracks and cover with the acrylic paste. This results in a flexible, nonshrinking repair that prevents cracks from reappearing as the building continues to settle.

These coatings require an ultraviolet curing lamp to reach full strength.

This thermally conductive coating keeps electrical components cool by dissipating heat.

Protect metal with these low-odor, water-based, UV-resistant coatings. They contain 316 stainless steel flakes, which provide durability and superior corrosion resistance.
