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.
OOMOO™ 25
No Vacuuming – No Scale – Easy To Use . . . OOMOO™ 25 is an easy to use tin cure silicone rubber compound that features a convenient one-to-one by volume mix ratio (no scale necessary). It has a low viscosity for easy mixing and pouring . . . vacuum degassing is not necessary. This product cures at room temperature with negligible shrinkage. OOMOO™ 25 has a 15-minute pot life and 75-minute cure time.
For The Novice Mold Maker - OOMOO™ silicones do not have great tear strength. They are good for making simple one or two-piece block molds. If you require a high tear strength silicone, Mold Max™ silicones are recommended.
OOMOO™ 25 is suitable for a variety of art-related and industrial applications including making one and two-piece block molds for sculpture and prototype reproduction, casting plaster, resins and wax. OOMOO™ silicones are also suitable for electrical potting and encapsulation applications.
