The Mold Star series are silicone rubbers that cure to become soft and strong rubbers, which are tear resistant and exhibit very low long term shrinkage.

Properties:

• 30A Shore hardness.
• Pot life: 45 minutes.
• Cure time: 6 hours at room temperature (73°F/23°C). 
• Colour: Blue.
• 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. 
• Low viscosity.
• Vacuum degassing not required.

Features:

• Molds made with Mold Star will last a long time. 
• Good for casting wax, gypsum, resins, concrete and other materials. 
• Molds are heat resistant up to 232°C / 450°F.
• Suitable for casting low-temperature metal alloys. 
• Not suitable for brush-on mold-making.

Important:

• This product will not cure against surfaces containing sulfur, even when sealed.
• Molds should be stored on a level surface in a cool, dry environment. 
• Applying A Release Agent - a release agent will make demolding much easier when casting into most surfaces. Ease Release 200 is a proven release agent for releasing silicone from silicone or other surfaces. 
• 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.
