Product Description
EpoxAcast™ 650 BLACK + 102 Hardener
EpoxAcast™ 650 Black is a mineral filled general purpose casting epoxy that is low cost and versatile. It features a low mixed viscosity for minimal bubble entrapment.
TASK™ 7
Flame Out™ is a low viscosity, fast set casting resin that meets UL 94 V-O requirements for flame resistance. It does not contain mercury, TDI or MOCA. Mix ratio is 1A:1B by volume. Pot life is 2.5 min. and demold time is 10 min. at 73°F / 23°C (depending on mass).
Fully cured Flame Out™ material is tough, durable, machinable and paintable. It has much higher physical and performance properties than any other flame rated urethane available anywhere. Vibrant colors and color effects are possible by adding SO-Strong™ color tints. Applications for Flame Out™ include making flame resistant prototype and architectural models, model toys, theme park and stage elements, durable miniatures and special effect props. Material can also be used for potting and encapsulation applications.
