Description
This liquid epoxy system is formulated for various fabrication applications. It includes a base and a slow hardener, is unfilled, low in viscosity, odorless, and cures at room temperature. The cured epoxy can be sanded, shaped, machined, drilled, tapped, and painted.
It can be used with reinforcements like S-Glass, E-Glass, Kevlar, and Carbon fibers for lay-up applications or composite parts. It can also be mixed with fillers such as fumed silica for gel coat applications. Other fillers can be added for fairing, filleting, or bonding applications.

Instructions
Avoid breathing fumes; use in a well-ventilated area. A NIOSH approved respirator is recommended. Wear safety glasses, long sleeves, and rubber gloves. Do not mix components in glass or foam containers. Use containers with straight sides and a flat bottom. Mixing sticks should be flat and stiff with defined edges for scraping.
Store and use materials at room temperature (23°C/73°F) at 55% relative humidity or less. Elevated temperatures will reduce pot life. Proper measurement and thorough mixing are essential for full cure properties. Use an accurate gram scale for best results. A small test application is recommended if performance is in question.
Applying A Release Agent
For releasing epoxy from non-porous surfaces, use Ease Release™ 200 or 205 to prevent adhesion.
Measuring / Dispensing
Accurate ratio measurements by volume or weight are required for proper curing. Use an accurate gram scale for best results. Stir Part A and Part B thoroughly before dispensing. Refer to specified mix ratios for proper measurements. Dispense Parts A and B in proper proportions into clean containers.
Adding Color
Color can be added with UVO™ or IGNITE™ colorants. Pre-mix color with Part A thoroughly before adding Part B.
Mixing
Ensure mixing utensils are clean. Mix Parts A and B thoroughly for at least 3 minutes. Scrape sides and bottom of the container several times. If using a drill mixer, follow with hand mixing to ensure thorough mixing. For coating, pour into a roller pan to extend pot life.
Adding Fillers
Dry fillers can be added. Pre-mix dry filler with Part A before adding Part B.
Lowering Viscosity
Epic™ Epoxy Thinner can lower the viscosity of some epoxies. It is not a solvent and can be added to improve flow-ability and reduce bubble entrapment.
Increasing Flexibility
Flexer™ Epoxy Flexibilizer can lower the durometer of some epoxies. When added in the proper proportion, the cured epoxy will be softer.
Important
Mixed epoxy is exothermic and generates heat. Do not use foam or glass mixing containers or pour sections thicker than 0.32 cm (1/8 inch). If a batch begins to exotherm, move it to an open-air environment.
Applying
The mixed epoxy is a low viscosity liquid that can be poured up to 0.32 cm (1/8 inch) thickness.
Laminating
Cut the bristles of a chip brush 30% for better control. Apply a gel coat of epoxy over the surface. Apply reinforcement fabric evenly into the gel coat. Use a stippling motion to work fabric into epoxy. Ensure fabric ply is saturated. Use plastic polyethylene spreaders if needed.
Alternate additional thin layers of epoxy and fabric. Add additional epoxy as needed. Use a lamination roller to evenly distribute epoxy and reduce air bubbles.
Cure Time
Refer to specified cure times at room temperature. Cured material will be hard and unable to penetrate with a fingernail. Cured epoxy can be dry sanded. Wear a NIOSH approved mask when machining or sanding.
Heat Curing
This product cures at room temperature. Cure time can be reduced by applying mild heat. A service temperature of 59°C (138°F) can be attained with a higher temperature cure. Allow epoxy to cure for 30 minutes, then cure for 1 hour at 93°C (200°F). Allow casting to cool before handling.
Painting
Cured epoxy can be painted with acrylic enamel paints. Let paint fully dry before use.
Removing Epoxy
For uncured epoxy, scrape as much material as possible. Clean residue with E-POX-EE KLEENER™, lacquer thinner, acetone, or alcohol. Follow safety warnings for solvents and ensure adequate ventilation.
