Silastic Thixo Additive is a thixotropic additive for thickening silicone into a paste, making it easier to brush-on (butter-on) for making skin moulds and for applying in vertical and in-situ applications.
It is compatible with all the Silastic, Durasil and Smartsil silicones and should be added at 3% to the mixed silicone base and catalyst.
