EpoxAmite® 103 is an easy-to-use liquid epoxy system formulated for a wide variety of fabrication applications. EpoxAmite® 103 includes the EpoxAmite® 100 Base and the EpoxAmite® 103 SLOW Hardener.  EpoxAmite® 103 is unfilled, low in viscosity, odorless and cures at room temperature. Cured epoxy displays exceptional physical and performance properties. It can be sanded, shaped, machined, drilled, tapped and painted.

EpoxAmite® 103 can be used with reinforcements such as S-Glass, E-Glass, Kevlar and Carbon fibers for lay-up applications or composite parts. EpoxAmite® 101 can also be mixed with fillers such as fumed silica for gel coat applications. Urefil® 3, Urefil® 7 and other fillers can be added for fairing, filleting or bonding applications.

Applications: Wet Lay-Up Lamination, General Bonding & Repair, Clear Coating - Gel Coating, Barrier Coating, Thin-Section Casting, Water Proofing, Patching & Small Laminates 

Also available: EpoxAmite® 101 FAST SET and EpoxAmite® 102 MEDIUM SET 

Adding Fillers - A variety of dry fillers can be added. Pre-mix dry filler with Part A before adding Part B.

Important - Mixed EpoxAmite® 100 Resin with EpoxAmite® 103 Hardener is exothermic, meaning it generates heat. A concentrated mass of mixed epoxy in a confined area such as a mixing container can generate enough heat to melt a plastic cup, burn skin or ignite combustible materials if left to stand for its full Pot Life. Do not use foam or glass mixing containers or pour sections thicker than 1/8” (0.32 cm). If a batch of mixed epoxy begins to exotherm, move it to an open air environment.


Applying – Mixed EpoxAmite® 103 is initially a low viscosity liquid that can be poured up to 1/8” (0.32 cm) thickness.

Laminating: cut the bristles of a chip brush 30% for better control. After epoxy is mixed, you must work quickly to apply multiple layers. Brush an initial gel coat of epoxy over surface. Apply reinforcement fabric evenly into gel coat. Using brush, gently use stippling motion to work fabric into epoxy. Ensure fabric ply is saturated. Plastic polyethylene spreaders may also be used.

Alternate additional thin layers of epoxy and fabric using above application method. Add additional epoxy as needed to wet out subsequent layers. Repeat as necessary until desired thickness is attained. After final layer of fabric is applied, use lamination roller to evenly distribute epoxy and reduce air bubbles. Be mindful of your Thin Film Working Time.


Cure Time: Refer to specified Cure Times in Handling Properties at room temperature depending on mass. Cured material will be hard and unable to penetrate with a finger nail. Cured epoxy can now be dry sanded. If machining or sanding, wear NIOSH approved mask to prevent inhalation of particles.

Heat Curing - This product will cure at room temperature and does not require heat. Cure time can be reduced by applying mild heat. The higher the curing temperature is, the higher the resulting Heat Deflection Temperature. With a higher temperature cure, a service temperature of 138°F / 59°C can be attained. Allow epoxy to cure for 30 minutes and then cure for 1 hour at 200°F / 93°C. Allow casting to cool to room temperature before handling.

Painting – Cured EpoxAmite® 103 can be painted and / or primed and then painted with acrylic enamel paints. Let paint fully dry before putting part into service.

Removing Epoxy – Uncured / Non-curing epoxy: Scrape as much material as possible from the surface using a scraper. Clean the residue with E-POX-EE KLEENER® available from Smooth-On, lacquer thinner, acetone or alcohol. Follow safety warnings pertaining to solvents and provide adequate ventilation.

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.
