Soft platinum-cure RTV-2 silicone gel for special effects

General Information

P-157 is an extremely soft, resilient silicone rubber gel. It is a two component, addition cure material that is sensitive to cure inhibition when in contact with sulfur, nitrogen or organo-tin containing materials. It can be used in conjunction with platinum cured special effect silicones to produce a realistic simulation of living tissue. It is a colorless, clear gel that can be colored by the use silicone dispersed pigment >. P-157 also has is a low viscosity that allows for easy mixing, deairing and pouring. This combination of properties makes P-157 well suited for special effects and movie making industries.
