| XP-540 silicone rubber is a translucent two-component, addition reaction, platinum catalyzed system that cures at room temperature. It is a higher durometer version of P-44. It has superb physical properties, excellent release and good chemical resistance. Applications: XP-540 is used to make molds where visual inspection is required. The combination of physical integrity and 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.&& |
