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\u003eEpoxAcoat® HT\u003c\/strong\u003e must be properly measured and thoroughly mixed to achieve full, high-strength, solid-cure properties. \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\/p\u003e\r\n\u003cp\u003e\u003cem\u003e\u003cstrong\u003eApplying A Release Agent\u003c\/strong\u003e \u003c\/em\u003e– For releasing epoxy from nonporous 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\r\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.\u003cbr\u003eUse 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: Pot life can be extended by pouring mixture into a shallow pan, reducing its mass.\u003c\/p\u003e\r\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 apply sections thicker than 1\/8” (0.32 cm). If a batch of mixed epoxy begins to exotherm, move it to an open air environment.\u003c\/p\u003e\r\n\u003cp\u003e\u003cem\u003e\u003cstrong\u003eApplying\u003c\/strong\u003e \u003c\/em\u003e– You will apply two thin layers of \u003cstrong\u003eEpoxAcoat™ HT\u003c\/strong\u003e 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. \u003cstrong\u003eNOTE\u003c\/strong\u003e: Pot life can be extended by pouring mixture into a shallow pan, reducing its mass.\u003cbr\u003eAfter 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 \u003cstrong\u003eEpoxAmite™ HT\u003c\/strong\u003e laminating resin and appropriate reinforcing material.\u003c\/p\u003e\r\n\u003cp\u003e\u003cstrong\u003e\u003cem\u003eCure Time -\u003c\/em\u003e \u003c\/strong\u003eRefer to specified Cure Times in Handling Properties at 73°F \/ 23°C depending on mass.
