The Smooth-Cast 300 series of liquid plastics are ultra-low viscosity casting resins that yield castings that are bright white and virtually bubble free. The differences between them are pot life and demold time.Vacuum degassing is not necessary. They offer the convenience of a one to one mix ratio (one part A to one part B by volume). Sold in two part kits; (example: 5 Gallon kit size is actually 10 gallons of product and consists of 5 gallons of Part A and 5 Gallons of Part B.)
These resins readily accept fillers (such as URE-FIL 3 from Smooth-On) and can be pigmented (Smooth-Cast 325 accepts pigments better than the SC 300 series.) 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, cold cast bronze castings, making prototype models, special effect props and decorative jewelry. Those interested in making roto cast pieces should refer to the Smooth-Cast ROTO™ technical bulletin.
