Ten-to-One / High Tear Strength Mold Rubber, 28 fl. oz.

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.



TEN-to-ONE / HIGH TEAR STRENGTH mold rubber is a special formula that is recommended for long-life molds having thin sections or deep undercuts that put extraordinary stress on mold rubber when castings are removed. Mix 10 parts of A with 1 part of B by weight (we recommend the use of #83825 Digital Scale, sold separately) and pour into mold box. Includes 2 lbs. of part A and 0.2 pounds of part B. 45 minute pot life; 24 hour cure. 2.2 lb. kit contains approx. 28 fl. oz. total material. Tin cure.



#82663 Special Note Vacuum de-airing is not necessary if the material is carefully blended (do not whip) and is poured in a thin stream from a high position. Brushing on a thin coat before pouring also helps to avoid air bubbles from forming on the surface of the pattern.
