Epoxies are the strongest and most weather- and chemical-resistant structural adhesives. They work especially well on metals. For putty adhesives, slice off the required amount, then knead it together to form a moldable adhesive.

These machinable epoxies are mixed with steel, but won’t rust, so they can be used to repair cracks and threaded holes. The strongest and most weather- and chemical-resistant structural adhesives, epoxies work especially well on metals. Slice off your required amount, then knead it together to form a moldable adhesive.

Use these glues for general purpose bonding and repairs.

This glue remains flexible after curing to accommodate joint movement. Glue that is FDA compliant 21 CFR 175.105 is suitable for food packaging. The 8" long glue sticks require a converter (sold separately) to use with a 3M or LT gun.

3764 stays flexible at low temperatures and works on hard-to-bond plastics. 3M glue sticks work only with 3M glue guns.

When heated, these glue sticks melt and quickly begin to harden. Use them to seal packaging and form other low- to medium-strength bonds. 3M glue sticks work only with 3M glue guns. The 8" long glue sticks require a converter (sold separately) to use with a 3M or LT gun.

Adhesives that take longer to harden are suited for applications that require some repositioning, because the longer open times allow for more adjustment. For high-volume applications, adhesives with a lower viscosity flow faster than other hot-melt adhesives.

3750LM is FDA compliant 21 CFR 175.105 for use in food packaging.

3762 is a high-tack adhesive; it bonds quickly with light pressure.

3789 joins hard-to-bond plastics and resists fuel and oil.

LM denotes low-temperature formulations. These work well on delicate or heat-sensitive materials.

Glue hardens in 15 seconds or less to bond quickly. Made of FDA listed materials, it is suitable for food packaging.

Paste threadlockers are easy to apply and won't drip, even from overhead fasteners. These threadlockers bond slightly oily parts. They begin to harden once coated surfaces are threaded together and exposure to air is blocked.

Threadlockers with medium locking strength require a hand tool to unthread.

Threadlockers with high locking strength require both heat and a hand tool to unthread.

This gel clings to fasteners to prevent drips. It begins to harden once coated surfaces are threaded together and exposure to air is blocked.

Primer (sold separately) cleans the surface and decreases the time to reach full strength. It is recommended when working with aluminum, stainless steel, and titanium; black-oxide finishes, and cadmium and zinc coatings.

Threadlockers in sticks dispense with a twist.

Encase electronic assemblies in a layer of material for protection from dust, moisture, chemicals, mechanical shock, and vibration. Hot-melt potting compounds have excellent flexibility, good chemical and moisture resistance, and withstand a range of temperatures. They provide good electrical insulation. Use 3M glue guns (sold separately) to dispense.

Mix these two-part surface fillers together to repair leaks and cracks as well as to rebuild rough spots in metal. The size listed is the combined total of the two parts.

NSF/ANSI 61 surface fillers meet safety standards for use with drinking water.

Surface fillers in a stick have a resin on the outside and a hardener on the inside. Cut the desired amount from the sticks, knead to a uniform color to mix, and press into place.

To stop leaks in metal tanks and equipment without draining the contents, heat the area with a heat gun or torch to melt the stick and form a permanent seal. The resulting patch can withstand pressure up to 600 psi. These sticks meet NSF/ANSI 61 safety standards for use with drinking water systems.

Stop leaks in metal tanks and equipment without draining the contents. Until a permanent repair can be made, rub these sticks into the leak to form a temporary seal.

Mix these two-part epoxy surface fillers to create a strong repair in wet environments or underwater. Use them to repair cracked, worn, and damaged surfaces. Size listed is the combined total of the two parts.

Putty fillers come in a stick with a resin on the outside and a hardener on the inside. Cut the desired amount from the sticks, knead to a uniform color to mix, and press into place. NSF/ANSI 61 surface fillers meet safety standards for use with drinking water.

Fill cracks in horizontal, vertical, and overhead concrete surfaces. Surface fillers that have a mix ratio are multi-part fillers. Size listed is the combined total of the parts.

Knead surface fillers in a stick to a uniform color to mix and press them into cracks in concrete floors, stairs, and walls. They can also be used to anchor bolts.

Use these two-part fillers to rebuild cracked or worn plastic surfaces. The size listed is the combined total of the two parts.

Surface fillers in a stick have a resin on the outside and a hardener on the inside. Cut the desired amount from the sticks, knead to a uniform color to mix, and press into place. Use with most rigid and semi-rigid types of plastic. They meet NSF/ANSI 61 for use with drinking water.
