PlatSil® Gel-10

PlatSil® Gel-10 is a unique, 1A:1B mix, liquid platinum silicone rubber with a 5-6 minute working time and a 30-minute demold time. It cures to a Shore A10 hardness. Use PlatSil Gel-10 as a mold rubber, to create prosthetic appliances, as well as for lifecasting.

Polytek offers an array of accessories that work independently or in concert to increase working time; accelerate cure time; thicken the mix for brushing/layering; thin the mix for easier pouring or for softening; or to “deaden” the rubber to soften and eliminate the snappy, synthetic look and feel of ordinary silicone rubbers. Deadened PlatSil Gel-10 can be made to look, feel and move like all types of living tissue. Unlike silicone fluid, Smith’s Theatrical Prosthetic Deadener and PlatSil Deadener LV (Low-Viscosity) do not leach from the cured rubber/appliance so bonding and use are far easier. Appliances can be pigmented fleshtone or any other color with Silicone Color Pigments and can be made self-sticking and reusable. Endless possibilities. For a softer PlatSil Gel, consider PlatSil Gel-OO (Shore OO30). For a harder option, consider PlatSil Gel-25 (Shore A25).
