Description
General Description
This liquid epoxy system is formulated for various fabrication applications. It includes a base and a fast 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 like fumed silica for gel coat applications. Additional fillers such as Urefil™ 3, Urefil™ 7, and others can be added for fairing, filleting, or bonding applications.

Instructions
Preparation
Avoid breathing fumes - use in a well-ventilated area. A NIOSH approved respirator is recommended. Wear safety glasses, long sleeves, and rubber gloves to minimize skin contact. 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. Properly measure and thoroughly mix components to achieve full, high-strength, solid-cure properties. Use an accurate gram scale for best results. Conduct a small test application to determine suitability for your project.
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. Stir parts thoroughly before dispensing. Refer to specified mix ratios for proper measurements. Dispense parts into clean plastic, metal, or wax-free paper 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 thoroughly for at least 3 minutes with a square-edged mixing stick. Scrape sides and bottom of the container several times. If using a drill mixer, follow with hand mixing to ensure thorough mixing. Pour into a roller pan to extend pot life if used for coating.
Adding Fillers
Dry fillers can be added. Pre-mix dry filler with Part A before adding Part B.
Lowering Viscosity
Epic™ Epoxy Thinner can be added to lower viscosity and improve flow-ability. It also aids in reducing bubble entrapment.
Increasing Flexibility
Flexer™ Epoxy Flexibilizer can be added to lower the durometer of the epoxy, making it softer or semi-rigid.
Important
Mixed epoxy is exothermic, generating heat. A concentrated mass can generate enough heat to melt a plastic cup, burn skin, or ignite combustible materials. Do not use foam or glass mixing containers or pour sections thicker than 0.32 cm (1/8 inch). Move exothermic batches 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 the bristles of a chip brush for better control. Apply multiple layers quickly. Brush an initial gel coat over the surface, apply reinforcement fabric evenly, and 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 at room temperature. Cured material will be hard and unable to penetrate with a fingernail. Wear a NIOSH approved mask when machining or sanding.
Heat Curing
This product cures at room temperature but can be heat-cured to reduce time. A service temperature of 59°C (138°F) can be attained with higher temperature curing. 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 off 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.
