SmartAdhesives' epoxy adhesives are among the strongest adhesives available, and formulated to perform in the most demanding environments. All our epoxies can handle temperatures ranging from -67F to 350F as well as resist solvents, water and even strong chemicals. Our semi-rigid and flexible epoxy adhesives (E3, E4, E5, E6) contain rubberized additives to provide a range of flexibility and impact resistance.

Our epoxy adhesives are designed to be dependable and easy to use. We use 100% solid material, without solvents, to eliminate VOCs and shrinkage upon curing. For simplicity, all our two-part epoxy adhesives are 1:1 mix ratios. We recommend our convenient cartridges with a mixing nozzle for easiest application. More: How to use epoxy adhesives

Things to know about epoxy adhesives

About Epoxy Adhesives

Epoxy adhesives are the most widely used structural adhesive, because of their excellent adhesion to most substrates, high strength, and light weight. Uses range from bolt anchoring, concrete repair, wood filling, and electronic encapsulation to manufacturing of sports equipment, aircraft, boats and wind turbine blades.

How They Work

Once thoroughly mixed, epoxy resin and hardener will react together to create a chemical chain-link fence that binds with itself and any material it touches. Applying heat of up to 200F degrees will accelerate this curing process. Epoxy adhesives link better with metals, wood, concrete, masonry, and composite plastics.


Epoxy resin that is improperly mixed with its hardener is the #1 cause of failure when using epoxy adhesives on clean surfaces. Mix resin and hardener until uniform color, then mix some more, or use a cartridge systems whenever possible.

Common Application Methods

Cartidges with an applicator gun (or caulking gun), trowel, brush, wooden tongue depressor or putty knife.

Did You Know?

Many of the fake rocks, trees, wooden signs at most amusement parks, including Disneyland, are made of epoxy!
