Preparation Avoid breathing fumes - use in a well ventilated area at minimum. NIOSH approved respirator is recommended. Wear safety glasses, long sleeves and rubber gloves to minimize skin contact. This material has a high exotherm (generates heat). Do not mix components in glass or foam containers. Materials should be stored and used in a room temperature environment (73F/23C). Elevated temperatures will reduce Pot Life. EpoxAcoat HT must be properly measured and thoroughly mixed to achieve full, high-strength, solid-cure properties. 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.
Applying A Release Agent
For releasing epoxy from nonporous surfaces such as resin, metal, glass etc., use Ease Release 200 or 205 to prevent adhesion.
Measuring / Dispensing
Accurate ratio measurements by weight are required for the material to cure properly and develop full physical properties. Dispense Parts A and B proper proportions into clean plastic, metal or wax-free paper containers.
EpoxAcoat HT can be colored with UVO colorants. Pre-mix colorant with Part A thoroughly and then add Part B.
Be sure mixing utensils are clean and free of any potential contaminants such as dirt, dust or grease. Mix Parts A and B thoroughly for at least 3 minutes with a square edged mixing stick. Be aggressive and scrape sides and bottom of mixing container several times. Use the square edge of mixing stick to bring material off of the sides of container and blend. If using a drill mixer, follow with hand mixing as directed above to ensure thorough mixing. NOTE: Pot life can be extended by pouring mixture into a shallow pan, reducing its mass.
A variety of dry fillers can be added. Pre-mix dry filler with Part A before adding Part B.
Important Mixed EpoxAcoat HT 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 apply sections thicker than .125" (0.32 cm). If a batch of mixed epoxy begins to exotherm, move it to an open air environment.
You will apply two thin layers of EpoxAcoat HT using a disposable chip brush. After epoxy is mixed, you must work quickly so that the mass in your mixing container does not set up prematurely. NOTE: Pot life can be extended by pouring mixture into a shallow pan, reducing its mass. After applying 1 thin layer of epoxy, let partially cure for 4 hours until "tacky hard". Apply a second thin layer and again partially cure for 4 hours until "tacky hard". Continue laminating process with EpoxAmite HT laminating resin and appropriate reinforcing material.
Refer to specified Cure Times in Handling Properties at 73F (23C) 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.
Post Curing - For Tools Made Using EpoxAcoat HT and EpoxAmite HT Epoxies
- Allow epoxy to cure on the pattern at room temperature for a minimum of 24 hours.
- Place tool and pattern in a cold oven. Set temperature to 150F (65C) and hold for 4 hours. You may attach support structure and demold tool after this step is completed, but for maximum stability, we recommend full post cure over pattern.
- After 4 hours, increase temperature to 200F (93C) and hold for 3 hours.
- After 3 hours at 200F (93C), increase the temperature to 250F (121C) and hold for 3 hrs.
- After 3 hours at 250F (121C), increase the temperature to 320F (160)C and hold for 3 hrs.
- After completion of the cure cycle, turn off the oven and allow the tool to cool to room temperature before removing part for clean-up and service.
Cured EpoxAcoat HT 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 EPOXEE KLEENER, lacquer thinner, acetone or alcohol. Follow safety warnings pertaining to solvents and provide adequate ventilation.
