Apply these lubricants to molds before casting so you can easily remove cast parts and prevent sticking, stretching, and tearing. They leave a residue, so they shouldn’t be used on parts that need to be painted.

Lubricants with silicone can be used with rubber and plastic. Sprayon MR 315 Urethane & Styrene Silicone Release Agent can be used with sensitive plastic, such as styrene and urethane.
