Polycraft GP-3481F Silicone is a Condensation Cure Mould Making Rubber
High strength silicone mould making rubber. Our silicone has been formulated for easy mixing by hand, with colour coded components (red or green) giving a visual aid to ensure mixing is adequate. The two components mix easily and because of the low viscosity most grades can be used without processing in a vacuum chamber. This silicone is suited for the detailed reproduction of figures, art objects and similar items.
FC-6600 / FC-6620 / FC-6630 / FC-6666 Polyurethane resins are not suitable to be used with condensation cure silicone, these resins must be used with addition cure silicone mould making rubber.
Outstanding release properties
Long working time
High tear resistance
High elasticity for easy removal of complex replica parts
Can be made thixotropic (non flowable) for vertical surface replication
Red silicone catalyst is by far the most popular catalyst to use with the GP-3481-F silicone, it gives great air release with longer working and demould times.
