Smooth-On Smooth-Cast 310 - Slowest Cure time

Smooth Cast 310 liquid plastic is an ultra-low viscosity casting resin. Does Smooth-cast 300 cure too fast for you? Problem solved! Smooth-Cast 310 cures the slowest of all the Smooth-cast 300 series with a 3-4 hour demold time and 15-20 minute pot life. It yields castings that are bright white and virtually bubble free. Vacuum degassing is not necessary. Smooth-Cast offers the convenience of a one to one mix ratio (one part A to one part B by volume). Fully cured castings are tough, durable, machinable and paintable. They resist moisture and mild solvents. Applications for Smooth-Cast Liquid Plastics include reproducing small to medium size sculptures,making prototype models, roto cast pieces, and special effect props. For rotational castings, check out Smooth-Cast 65d!
