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.

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