Pot life is 1 hour and cure time is 24 hours at 73°F \/ 23°C (post cure required – see post cure schedule). Ultra-low viscosity ensures uniform wetting out and fast penetration of reinforcement materials during hand lay-up or vacuum infusion processes. Cured resin offers superior physical properties.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eEpoxAmite™ HT High Temp Laminating Epoxy\u003c\/strong\u003e can be used with S-Glass, E-Glass, Kevlar and carbon fibers for making composite tooling or parts.  Applications include making high temperature pre-preg parts, bonding fixtures, vacuum form molds and prototype injection molds.\u003cbr\u003eUse as a backup laminating resin for \u003cstrong\u003eEpoxAcoat™ HT high temperature surface coat epoxy\u003c\/strong\u003e.\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003e\u003cstrong\u003ePreparation\u003c\/strong\u003e\u003c\/em\u003e – 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.\u003cbr\u003eMaterials should be stored and used in a room temperature environment (73°F\/23°C). Elevated temperatures will reduce Pot Life. \u003cstrong\u003eEpoxAmite™ HT\u003c\/strong\u003e must be properly measured and thoroughly mixed to achieve full performance properties. \u003cem\u003e\u003cstrong\u003eBecause 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.\u003c\/strong\u003e\u003c\/em\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003e\u003cstrong\u003eApplying a Release Agent\u003c\/strong\u003e \u003c\/em\u003e– For releasing epoxy from non-porous surfaces such as resin, metal, glass etc., use \u003cstrong\u003eEase Release™ 200 or 205\u003c\/strong\u003e (available from Smooth-On) to prevent adhesion.\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003e\u003cstrong\u003eMeasuring \/ Dispensing\u003c\/strong\u003e\u003c\/em\u003e – Accurate ratio measurements by weight are required for the material to cure properly and develop full physical properties.

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. \u003cstrong\u003eIf using a drill mixer\u003c\/strong\u003e, follow with hand mixing as directed above to ensure thorough mixing. \u003cstrong\u003eNOTE\u003c\/strong\u003e: If mixture is to be used for coating, pour into a roller pan to extend Pot Life.\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003e\u003cstrong\u003eAdding Fillers\u003c\/strong\u003e\u003c\/em\u003e - A variety of dry fillers can be added.

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\/2” (1.28 cm). If a batch of mixed epoxy begins to exotherm, move it to an open air environment.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cem\u003eApplying – Pouring -\u003c\/em\u003e\u003c\/strong\u003e Mixed \u003cstrong\u003eEpoxAmite™ HT\u003c\/strong\u003e is initially a low viscosity liquid that can be poured up to 1\/2” (1.28 cm) thickness.\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003e\u003cstrong\u003eLaminating - \u003c\/strong\u003e\u003c\/em\u003eAfter epoxy is mixed, you must work quickly to apply multiple layers.
