The more solvent added, the longer XTC-3D® will take to cure. Cured material will be more flexible. 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. Measuring and Dispensing – You need to be accurate in measuring for XTC-3D™ 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).

Adding Color - XTC-3D™ can be colored with UVO™ or IGNITE™ colorants. Pre-mix color with Part A before combining with Part B. Post Finishing: Cured material can be machined or sanded (wear NIOSH approved respirator mask to prevent inhalation).Protective coating for smoothing and finishing 3D printed parts that does not melt plastic. XTC‑3D® fills in 3D print striations and creates a smooth, high gloss finish. The need to post finish is almost eliminated. XTC‑3D® can be applied to both SLA and SLS prints. It works with PLA, ABS, Laywoo, Powder Printed Parts and other rigid media such as EPS, EPDM and urethane foam as well as wood, plaster, fabric, cardboard and paper.

Applying XTC-3D® - Use a disposable chip brush or foam brush to apply XTC-3D®. 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. XTC-3D® bonds to itself. If Making Molds of Models Coated with XTC-3D™: Liquid mold making rubbers will adhere to cured XTC-3D™. Before mixing and applying Smooth-On silicone or urethane mold making rubbers, apply a thorough coating of Ease Release™ 200 or 205 release agent over cured XTC-3D™ and let dry. Preparation – Materials should be stored and used in a room temperature environment (23°C). Elevated temperatures will reduce Pot Life. XTC-3D® Part A resin and Part B Hardener must be properly measured and thoroughly mixed to achieve full, high-strength, solid-cure properties.Personally I will say follow the instructions and you will not go wrong; that includes measuring very carefully, to the instructions, the volumes you mix together. Interesting comment from @phantom on temperature; I have always applied it in a room with a minimum temp. of 20c. Preparation – Materials should be stored and used in a room temperature environment (73°F/23°C). Elevated temperatures will reduce Pot Life. XTC-3D™ Part A resin and Part B Hardener 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.

Any product that you have subsequently cut, shaped, broken or modified, unless found to be faulty or defective. XTC-3D is an epoxy resin that mixes by volume rather than weight, which is a lot easier. A very small amount of XTC-3d is needed to coat a 3D print. With 1oz of mixed XTC-3D you can cover three Phil’s. Now, let’s get started: After the job is done, leave the model to dry. It takes about 2-3 hours at room temperature, in the winter, in a garage, at a temperature of a few degrees above zero, the resin will take all day to dry up. As for the container, we leave it to dry as well. The dried resin comes easily away from the container walls when you bend them a little. There is a problem with the brush, though. You could toss it into the container with a solvent, but it is in fact only a half-measure, because the resin will never come away completely. If you leave the brush to dry, you may as well throw it away. It is therefore sensible to use rather cheap tools, because the lifetime of the brushes is very limited when working with the XTC-3D. Extending Working Time - 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.
