Product Description
XTC-3D™
XTC-3D™ is a protective coating for smoothing and finishing 3D printed parts. Two liquids are mixed together and brushed onto any 3D print. Coating self-levels and wets out uniformly without leaving brush strokes. Working time is 10 minutes and cure time is about 4 hours (depending on mass and temperature). XTC-3D™ cures to a hard, impact resistant coating that can be sanded, primed and painted. Adding colors and metal effects is easy.
Smooth-Cast™ 60D
The Smooth-Cast™ Semi-Rigid line of low-cost semi-rigid urethane casting resins cure quickly to semi-rigid plastics that offer exceptional strength and impact resistance.
New Formulations – New Look!
Smooth-Cast™ 60D is newly reformulated with a translucent white appearance and improved physical properties. All Smooth-Cast semi rigids are now mercury free and phthalate free. These plastics are easy-to-use (mix ratio is 1A:1B by volume) and have low viscosities for minimal bubble entrapment. Vibrant colors are possible by adding SO-Strong™, UVO™ or Ignite™ color pigments.
These semi-rigid plastics are good for making impact resistant prototypes, models, toys, props, climbing holds, etc.
