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

Simplify and speed up hole repairs—stick a patch over the area and cover with spackling compound.

Tape hides seams and smooths out corners. It has an adhesive back for bonding and requires joint compound for finishing. It can also be used to repair damaged walls.

Use this kit to prevent bull's eye breaks and minor chips from getting bigger.

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

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

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

Tested to meet ASTM E595, a standard used by NASA, these sealants fill joints and seams while releasing almost no volatile emissions that could damage sensitive electronics, even in a vacuum.

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.

Meeting requirements for semiconductor, biomedical, and electronics clean rooms, these sealants won’t contaminate air and surfaces.

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

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

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

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

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

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.

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

This tape has a higher density than standard tape for a better seal between threads.

This tape contains nickel to prevent seizing and galling associated with stainless steel threaded connections. It’s also good for use with other metals.

Much thicker than sealants for fine threads, these sealants bridge the gaps between coarse threads.

Apply this thread sealant stick without a mess.

PTFE provides a slippery surface that keeps threads from binding. These sealants never fully harden, remaining pliable enough to self-heal and stop leaks before they start.

These sealants come in bottles, cans, and tubes so you can choose the quantity that covers your application.

Formulated for high lubricity, these sealants allow easy assembly of finely threaded hydraulic and compressed air system components. They're also free of fillers that could contaminate system media.

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

These sealants don't degrade in sunlight.

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

A thin layer of aluminized fiberglass on this silicone foam reflects heat to protect sensitive equipment.

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

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

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

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

Bond most materials without the strong odor of other epoxy adhesives.

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

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

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

Invisibly bond glass and transparent plastics.

Often used on diesel engines, exhaust systems, and gas turbines, these adhesives withstand high temperatures and provide excellent electrical insulation.

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

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

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

These small tabs of pressure-sensitive adhesive offer convenient, no-mess bonding.

This glue withstands temperatures up to 500° F.

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

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

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

Hook-and-loop fasteners make it easy to install, remove, and reuse this flexible insulation. Use on steam, hot water, and process pipes and fittings.

This common insulation material is typically used on hot and cold water lines and in process piping.

Able to withstand temperatures as low as -290° F, these super-thin, lightweight sheets are made of fiber-reinforced silica aerogel that can flex into tight spaces other insulation can't. Use in process piping and power-generating applications.

Typically used in ovens and furnaces, these are the most efficient of our rigid high-temperature insulation sheets. Please note that they require special care when installing since the crumbly material is difficult to work with and will crack easily. Sheets lose strength over time and are intended to be installed behind another facing or insulation material.

Made of flexible composite paper, these sheets won't shrink or lose shape in the high temperatures of air furnaces and hot water tanks.

Wrap rectangular and round ductwork with this flexible insulation.

Made with indium this solder is soft and malleable—even as temperatures approach absolute zero—allowing this solder to form an airtight seal between metal and certain non-metal materials. Thanks to its ribbon shape, this solder is easier to use on large, flat areas than wire solder.
