P-45 Silicone Rubber is a two-component, addition reaction, platinum catalyzed system that cures at room temperature. It has a moderate durometer, superb physical properties, excellent release and good chemical resistance.
P-45's outstanding combination of physical integrity and moderate hardness make it an excellent choice for prototyping. Due to its flexibility and ease in releasing it performs well with expandable foam systems maintaining its shape and detail for multiple castings.
