Elevated temperatures will reduce Pot Life. \u003cstrong\u003eXTC-3D™\u003c\/strong\u003e Part A resin and Part B Hardener must be properly measured and thoroughly mixed to achieve full, high-strength, solid-cure 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\r\n\u003cp\u003eAvoid eye and skin contact. Avoid breathing fumes - use in a well ventilated area. 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.\u003c\/p\u003e\r\n\u003cp\u003e\u003cstrong\u003e\u003cem\u003eCoverage \u003c\/em\u003e–\u003c\/strong\u003e A very small amount of \u003cstrong\u003eXTC-3D™\u003c\/strong\u003e is needed to coat an average size 3D print. 1 oz \/ 28.3 grams of mixed material will cover 101 in2 (651 cm2 ) applied at 1\/64” (.04 cm) thickness. Pre-Mix Part B: Before using, shake container vigorously.\u003c\/p\u003e\r\n\u003cp\u003e\u003cstrong\u003e\u003cem\u003eMeasuring and Dispensing\u003c\/em\u003e –\u003c\/strong\u003e You need to be accurate in measuring for \u003cstrong\u003eXTC-3D™\u003c\/strong\u003e to cure properly. Parts A and B can be measured by either volume or weight. Dispense proper proportions of parts A and B into clean plastic, metal or wax-free paper containers (do not use foam or glass cups).\u003c\/p\u003e\r\n\u003cp\u003e\u003cstrong\u003e\u003cem\u003eExtending Working Time \u003c\/em\u003e-\u003c\/strong\u003e If left in a mixing cup with a concentrated mass, pot life will be short and material may cure in your cup due to exotherm. Important - Reduce the mass of the mixture to increase working time. Example: layer two sheets of aluminum foil together and create a single-use flat tray with vertical sides to contain the liquid resin. After mixing parts A and B, pour mixture into the aluminum foil to reduce the mass. Your working time will be significantly increased.\u003c\/p\u003e\r\n\u003cp\u003e\u003cstrong\u003e\u003cem\u003eMixing \u003c\/em\u003e–\u003c\/strong\u003e Be sure mixing utensils have a square edge and are clean. Combine and mix proper amounts of Parts A and B. Mix thoroughly for at least 1 minute. Aggressively scrape the sides and bottom of mixing container several times. Use the square edge of mixing stick to bring material off of the sides and bottom of container and blend.\u003c\/p\u003e\r\n\u003cp\u003e\u003cstrong\u003eImportant - Mixed XTC-3D™ Resin is exothermic, meaning it generates heat. A large, concentrated mass of mixed material in a container can generate enough heat to melt a plastic cup, burn your skin or ignite combustible materials. If material begins to exotherm, move it outside to an open air environment.\u003c\/strong\u003e\u003c\/p\u003e\r\n\u003cp\u003e\u003cstrong\u003e\u003cem\u003eAdding Color\u003c\/em\u003e -\u003c\/strong\u003e \u003cstrong\u003eXTC-3D™\u003c\/strong\u003e can be colored with \u003cstrong\u003eUVO™\u003c\/strong\u003e or\u003cstrong\u003e IGNITE™ \u003c\/strong\u003ecolorants.

To achieve the thinnest coating possible we recommend applying material with a foam brush. Brushing on one thin layer of mixed material is recommended for most prints to create a smooth, uniform coating: less than 1\/64“(.039 cm). To avoid drips and runs, continue brushing and working the surface until the resin begins to set up. For particularly complicated prints with intricate detail you may want to coat one a section at a time for better control. \u003cstrong\u003eXTC-3D™\u003c\/strong\u003e bonds to itself.\u003c\/p\u003e\r\n\u003cp\u003e\u003cstrong\u003e\u003cem\u003eIf Adding More Layers\u003c\/em\u003e - \u003c\/strong\u003eallow first layer to partially cure until “tacky hard” before applying the next layer.
