How should I store Polytek 74-30?

Using a high-quality mold release agent is essential for successfully demolding pieces cast with Polytek 74-30. Look for silicone-based or water-based release agents that are compatible with polyurethane rubber. Apply a thin, even coat to the mold surface before pouring the material. This precaution helps prevent sticking, leading to smoother finishes and easier separation of your final product from the mold.

Can I use Polytek 74-30 for outdoor applications?
