Accelerator for TinSil (Tin Cure) formula silicones. Use TinSil FastCat in place of any TinSil Part A in order to accelerate cure and shorten demold time. FastCat can be used in a range of 2-6 parts per 100 parts B. Often used for reducing time needed between coats when TinSil rubbers are used to make brush-on blanket molds.
Important! Do not use in PlatSil formulas!
Use of FastCat can shorten the library life of cured TinSil rubber.
