Smooth Cast 300 is a very low viscosity casting resin that does not need vacuum degassing, and yields virtually bubble-free solid bright white plastic castings in as little as 10 minutes depending on the mass and mold configuration.  Your fully cured castings are tough, durable, machinable, and paintable. They resist moisture and mild solvents and are great for reproducing small to medium size sculptures, original models, making prototype models, decorative jewelry and items, special effects props, you name it.

This resin is perfect to use for pouring into rubber molds, but you can also pour it into alginate molds, such as Smooth-on Alja-Safe, MM-1031 , or over clay sculptings that have a proper retaining wall around them.  Smooth Cast is superior for cold cast metal applications too and castings can be displayed outdoors after priming and painting.  See video below for demonstration of this product:



Smooth-Cast® 300 has a 3 minute Pot Life with a 10 minute demolding time, depending on mass.  It has an ultimate tensile strength of 3000 psi, and a Shore D Hardness of Shore 70D. Please note that a release agent (such as Mann Ease Release 200, MM-1313, is required to remove cured urethane plastic from most surfaces.
