About Structural Adhesives

Quick-Set Epoxy Structural Adhesives

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

Optically Clear Epoxy Structural Adhesives

For invisible bond lines, these adhesives dry clear.

Toughened Epoxy Structural Adhesives

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

Slow-Set Epoxy Structural Adhesives

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

Low-Odor Epoxy Structural Adhesives

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

Flame-Retardant Epoxy Structural Adhesives

These self-extinguishing epoxies meet UL 94 V-0 for flame retardance.

Submersible Anchoring Adhesives for Concrete

When concrete is saturated or submerged in water, use these adhesives to form strong bonds.

Anchoring Adhesives for Concrete

Permanently set threaded rods, studs, and rebar in concrete.

High-Temperature Anchoring
Adhesives for Concrete

These adhesives maintain their strength at temperatures up to 250° F.

Sealing and Coating

Surface Fillers

These surface fillers can be used on vertical surfaces without sagging. They repair cracked, worn, and damaged surfaces.

Surface Filler Patches

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

Light-Activated Surface Fillers

Press these putty surface fillers in place to fill in holes, cracks, and dents. When exposed to sunlight or a UV lamp, they begin to harden immediately.

Light-Activated Surface Filler Patches

An easy way to make repairs in the field. Cut patches to size, peel off the backing, and press into place. Expose them to sunlight or a UV lamp and they begin to harden immediately.

Water-Resistant Surface Fillers

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

Water-Resistant Surface Filler Kits

Everything you need to repair cracked, worn, and damaged surfaces—even underwater.

Surface Fillers for Metal

Mix these two-part surface fillers together to repair leaks and cracks as well as to rebuild rough spots in metal.

Chemical-Resistant Surface Fillers for Metal

Chemicals will not affect these two-part epoxies. They repair cracked, worn, and damaged surfaces.

Concrete Patching Compounds

Patch concrete floors, stairs, and walls with these compounds.

Concrete Surface Fillers

Fill in and shape horizontal, vertical, and overhead concrete surfaces, such as steps and columns.

Heavy Duty Coatings for Electronics

Thinner than potting compounds, these rigid and wear-resistant coatings flow easily into small spaces between electrical components. Use them to secure and insulate hardware on printed circuit boards.

Optically Clear Epoxy Potting Compounds

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

High-Purity Urethane Potting Compounds

This potting compound is formulated for use in sensitive applications such as manufacturing semiconductors.
