Smooth-On Smooth-Cast 300 Series
Smooth-On Smooth-Cast 300 Series of liquid plastics are ultra-low viscosity casting resins that yield castings that are bright white and virtually bubble free. Vacuum degassing is not necessary.

Product Details
Note: These resins readily accept fillers (such as URE-FIL® 3 ) and can be colored with SO-Strong® or Ignite® color tints but the Smooth-Cast 325 Color Match series accepts them better.
Applying A Release Agent – A release agent is necessary to facilitate demolding when casting into or over most surfaces. Use a release agent made specifically for mold making (Universal® Mold Release or Mann’s Ease Release® 200 available from Smooth-On or your Smooth-On distributor). A liberal coat of release agent should be applied onto all surfaces that will contact the plastic.
