Our two-part liquid RTV (Room Temperature Vulcanizing . . . cures without heat) silicone mold rubber is ideal for making duplicate parts with our casting resins. To make a mold, mix parts A and B together and pour into a mold box containing your pattern. After curing, the mold is soft and pliable and reproduces every detail of your pattern. And, because it is genuine silicone rubber (withstands up to 600 degrees F short-term; 450 degrees F continuous), you can use these molds to cast small metal parts with our low-temperature alloys. Instructions for making molds are included.


ONE-to-ONE / EXPRESS is an economical, super-fast cure, general purpose mold rubber that is easy to mix: Simply stir equal volumes of A and B together and pour. Use many times to make multiple resin castings, even those with slight undercuts. 6 minute 'pot' life, 30 minute cure. Blue color. De-airs without vacuum. 2.6 lb. kit contains approx. 32 fl. oz. total material. Platinum cure.*

*Molds made with platinum cure silicones exhibit the lowest long-term shrinkage and have the longest usable life.
