SMOOTH-CAST 326 plastics are were developed specifically for adding color pigments and fillers to achieve true color representation or filler effect. Small amounts of pigment will yield accurate, vivid colors from cured castings using So-Strong tints pigments. Applications include making pigmented prototype models or figures, special effect props, reproducing small to medium size sculptures, decorative jewelry, etc.

Properties:

• Produce castings that are bright white and virtually bubble free.
• Fully cured castings are tough, durable, machinable and paintable.
• Castings resist moisture and mild solvents. 
• Shore D hardness: 72.
• Pot life: 9 minutes.
• Cure time: 60 minutes at room temperature (73°F/23°C). 
• Colour: Clear Amber.
• Viscosity: Ultra Low

Features:

• Easier to color using SO-Strong color tints.
• Low viscosity for easy mixing and pouring.
• Comes in 2 parts: Part A and Part B. Part A and Part B are to be mixed in 1A:1B volume. No weighing scale is necessary. 

Important:

• Note: Large mass castings will get very hot and shrink more, depending on mold configuration.
• 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 such as the Ease Release 200 available from our online store. A liberal coat of release agent should be applied onto all surfaces that will contact the plastic.
• Safety - Use in a properly ventilated area (“room size” ventilation). Wear safety glasses, long sleeves and rubber gloves to minimize contamination risk. Wear vinyl gloves only. Latex gloves will inhibit the cure of the rubber.
• Store and use material at room temperature (73°F/23°C). Warmer temperatures will drastically reduce working time and cure time. Storing material at warmer temperatures will also reduce the usable shelf life of unused material.
