| Por-A-Mold and Por-A-Kast Por-A-Kast and Por-A-Mold are complementary urethane-based molding and casting products that can be used separately, but are often used in combination to create exceptionally durable and detailed castings of objects. Together, they are an ideal combination for sculpture and modeling. Por-A-Mold. A room-temperature curing, two-component urethane rubber mold making system that's ideal for artwork and special effects(not to be used on skin.) When blended in a one to one ratio by volume, it gives molds of superior quality and high reproductive fidelity for use with resin, epoxy, wax, plaster, and other casting materials. Molds will not shrink or soften with age and should remain usable for 20 years or more. To avoid damage to your artwork, we recommend the use of Synlube 531 Wax-Based Mold Release Agent.
