EA-40™ Epoxy glue

Buy Smooth-On at FormX

Smooth-On is one of the worlds leading manufaturers 3D modeling materials such as mold-making, casting and special effects materials but also industrial casting resins, adhesives and equipment. FormX is main distributor of Smooth-On products in Europe.

EA-40™ Clear Amber Epoxy is an unfilled low-viscosity epoxy adhesive that can be spread easily in thin films that are almost transparent after curing. EA-40™ has a long pot life and cures in 24 hours at room temperature to provide good mechanical and electrical properties. Mix ratio is 1:1 by volume. When mixed 2A:1B by volume, EA-40™ will achieve greater heat resistance and improved physical properties. EA-40™ is versatile and can be used for many different assembly and repair applications ranging from electrical potting to jewelry assembly to repairing plumbing fixtures. Bow makers have come to know EA-40™ as a tremendous laminating resin. EA-40™ provides highly moisture resistant bonds meeting the performance requirements for Federal Specification MMM-A-188, Type III.

Safety Information


Safety - Use in a properly ventilated area (“room size” ventilation). Wear safety glasses, long sleeves and rubber gloves to minimize contamination risk.

Store and use material at room temperature 23°C. This product has a limited shelf life and should be used as soon as possible.

A clean, dry surface is a necessary prerequisite for adhesive bonding. Adhesives will stick to either the surface of which a bond is desired or to that film of extraneous material directly on that surface. Rarely can a structural adhesive penetrate through surface contaminants to provide an optimum bond on an unclean surface.

Porous materials are simple to bond, provided they are dry. The surface should be sanded till clean and free from dust. Non-porous surfaces, such as found on metal and plastic materials, should be degreased, dried and roughened by sanding, sandblasting or chemical etching. The etched or sandblasted surfaces should be covered within a few hours of treatment to prevent contamination.

Handlers should wear clean cotton gloves to prevent body oils from contaminating the clean surfaces.

Epoxy adhesives do not perform well on metals such as nickel, chromium, tin or zinc nor on soft thermoplastics like polyethylene.

Because no two applications are quite the same, a small test application to determine suitability for your project is recommended if performance of this material is in question.

MEASURING & MIXING - Measure equal amounts of Parts A and B (or 2A:1B) by volume into a clean mixing container. Mixing tools and containers should be clean and made of metal, glass or plastic. After dispensing required amount of Parts A and B into mixing container, mix thoroughly for 3 minutes making sure that you scrape the sides and bottom of the mixing container several times.

Application - Apply to prepared surface and let cure for 24 hours. Applying mild heat will cure EA-40™ faster 65°C for 6 hours.

Post Curing - After EA-40™ has cured at room temperature, heating the epoxy to 65° C for 4 to 8 hours will increase physical properties and performance. Let cool to room temp. before moving bonded substrates, machining, etc.

To Attain Maximum Heat Distortion Temperature -
let cure for 24 hours at room temperature, heat cure for 2 hours at 122°C

At mix ratio 1A:1B – HDT will be 73°C.

At mix ratio 2A:1B – HDT will be 103 °C
