PlatSil® 71-30 Silicone Rubber
PlatSil® 71-30 is a 1A:10B mix, mid-range hardness, platinum silicone liquid mold rubber. Molds made from this rubber offer long library life, no shrink on cure, high strength and high chemical resistance.
Molds made with this rubber are excellent for resin casting (e.g., polyurethane, polyester, epoxy), foam casting, soap and candle making, taxidermy, prototyping applications, hobby reproduction, and more. Release agents are not necessary for most casting materials.
PlatSil 71-30 can be poured as supplied or thickened for brushing using PlatThix liquid thickener.
