About Structural Adhesives

Epoxy Structural Adhesives

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.

Optically Clear Epoxy Structural Adhesives

For invisible bond lines, these adhesives dry clear. Epoxies are the strongest and most weather- and chemical-resistant structural adhesives. Choose an epoxy that hardens quickly for fast repairs, or one that hardens slowly to allow more time for positioning.

The size listed is the combined total of the two parts.

Waterproof Epoxy Structural Adhesives

Even when used under water, these adhesives maintain their strength. The most weather- and chemical-resistant structural adhesives, epoxies tend to work especially well on metals.

The size listed is the combined total of the two parts. For putty adhesives, slice off the required amount, then knead it together to form a moldable adhesive.

ClearWeld and Plastic Bonder can be applied to wet surfaces.

WaterWeld and 11801, as well as one-time-use packets, can be applied to wet surfaces or under water.

Metal-Reinforced Epoxy Structural Adhesives

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.
