Epoxy Structural Adhesive Assortments

Easily handle a variety of small jobs. Assortments include eight different epoxies in 0.1-oz. packets. The strongest and most weather- and chemical-resistant structural adhesives, epoxies work especially well on metals.
Epoxy Type (For Joining) | Each | |
Easy Flowing (Composites, Metal) Fast Hardening (Masonry, Metal, Rubber) For Vertical Surfaces (Masonry, Metal, Wood) General Purpose (Masonry, Metal, Plastic, Rubber) High Strength (Metal, Rubber) Machinable Surface Filler (Composites, Metal) Optically Clear (Glass, Metal) Water Resistant (Composites, Masonry, Metal) | 0000000 | 000000 |
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.
These have two parts that must be mixed. The size listed is the combined total of the two parts.

Conductive Surface Fillers for Electronics

A high silver content allows these surface fillers to conduct electricity and heat. Use them to fill gaps and rebuild missing material on electrical connections or to assemble new components. They come as two parts. The size listed is the combined total of the two parts.
Volume resistivity measures how well a material opposes the flow of electricity. The lower the rating, the more electricity it conducts.
Thermal conductivity measures a material’s ability to transfer heat. The higher the rating, the more heat it transfers.
