SuperTIN (30 Shore DIY) Silicone Rubber (Tin Cure Silicone Rubber) - Make your own Molds/Moulds (1000gm + 37gm)

Key Characteristics: Cost & Accessibility: Generally more affordable and much easier to mix (often 1000gm:37gm by weight) than platinum silicones. Cure Reliability: Unlike platinum silicones, tin cure silicones are not susceptible to "cure inhibition." They can successfully cure against almost any surface, including sulfur-based clays. Shrinkage: They experience slight shrinkage (typically around 0.3%) over time as the mold ages. Lifespan: The molds have a limited library life (about 1 to 10 years) and will slowly degrade or become brittle after repeated pours. Safety: They release trace amounts of alcohol while curing and are not skin-safe or food-grade. Typical Applications: - Resin & Concrete Casting: Frequently utilized to cast urethane, epoxy, and polyester resins. - Prototype Molds: Excellent for capturing fine details on sculptures, prototypes, and decorative craft pieces. - Wax & Plaster: The standard choice for casting candles and gypsum. - Low-Melt Metals: Certain formulations are heat-resistant enough to cast low-melting-point metal alloys such as pewter.
