Description
This liquid epoxy system is designed for a range of fabrication applications. It includes a base and a medium hardener, is unfilled, low in viscosity, odorless, and cures at room temperature. Once cured, it 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. Additional fillers can be added for fairing, filleting, or bonding applications.

Instructions
Use in a well-ventilated area. A NIOSH approved respirator is recommended. Wear safety glasses, long sleeves, and rubber gloves. Avoid using glass or foam containers for mixing. Use containers with straight sides and a flat bottom. Mixing sticks should be flat and stiff.
Store and use materials at room temperature (23°C/73°F) with 55% relative humidity or less. Elevated temperatures will reduce pot life. Proper measurement and thorough mixing are crucial for achieving full properties. Use an accurate gram scale for best results. Conduct a small test application if performance is in question.
Applying A Release Agent
For non-porous surfaces, use Ease Release™ 200 or 205 to prevent adhesion.
Measuring / Dispensing
Accurate ratio measurements by volume or weight are required. Use an accurate gram scale. Stir Part A and Part B thoroughly before dispensing. Refer to specified mix ratios for proper measurements. Dispense Parts A and B into clean containers.
Adding Color
Color with UVO™ or IGNITE™ colorants. Pre-mix color with Part A, then add Part B.
Mixing
Ensure mixing utensils are clean. Mix Parts A and B for at least 3 minutes. Scrape sides and bottom of the container. If using a drill mixer, follow with hand mixing. For coating, pour into a roller pan to extend pot life.
Adding Fillers
Pre-mix dry filler with Part A before adding Part B.
Lowering Viscosity
Epic™ Epoxy Thinner can lower viscosity and improve flow-ability. It is not a solvent and can be added in different proportions.
Increasing Flexibility
Flexer™ Epoxy Flexibilizer can lower the durometer of the epoxy. When added in the proper proportion, the cured epoxy will be softer.
Important
Mixed epoxy is exothermic. Do not use foam or glass 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
Initially a low viscosity liquid, it can be poured up to 0.32 cm (1/8 inch) thickness.
Laminating
Cut brush bristles for better control. Apply a gel coat of epoxy, then reinforcement fabric. Use a stippling motion to work fabric into epoxy. Ensure fabric ply is saturated. Use a lamination roller to distribute epoxy and reduce air bubbles.
Cure Time
Refer to specified cure times. Cured material will be hard. If machining or sanding, wear a NIOSH approved mask.
Heat Curing
Cures at room temperature but can be heat-cured to reduce time. A higher curing temperature increases the heat deflection temperature. Allow epoxy to cure for 30 minutes, then cure for 1 hour at 93°C (200°F).
Painting
Cured material can be painted with acrylic enamel paints. Let paint dry before use.
Removing Epoxy
For uncured epoxy, scrape off material and clean residue with E-POX-EE KLEENER™, lacquer thinner, acetone, or alcohol. Follow safety warnings for solvents.
