Smartsil is our budget silicone developed to give the maximum economy, while still providing good quality reproduction and low shrinkage. Particularly suited to plaster casting. Smartsil thickens well for brush-on applications, using Silastic Thixo Additive.


Smartsil Soft is softer and more flexible than the standard Smartsil and being softer is obviously better for moulds with heavy undercuts making demoulding easier.


Smartsil Soft Silicone Catalyst is a red pigmented catalyst that is added at 25% to the base silicone.
