This crystal clear Polyester Casting Resin can go into any mold to make a paperweight, sculpture or jewelry. This resin is a crystal clear, low viscosity liquid that requires mixing with the included catalyst to become rock hard. It cures to a smooth glossy transparency at room temperature. Use of a mold release is not necessary for flexible plastic or rubber molds.  For deep flex molds, Castin' Craft mold release and conditioner is highly recommended.

This casting resin only has a 6 month shelf life. Store away from direct sunlight and in an area where room temperature is generally 70 to 72 degrees F.  A NIOSH approved respirator for fumes is urged to be worn when using this product.  Click here for full instructions, including casting advice.
