Discover the ultimate solution for your mold making and industrial applications with Smooth-On's Econ 80. This economical Shore 80A urethane rubber offers a faster cure alternative to our popular PMC 780, with lower physical properties. Designed for ease of use, Econ 80 features a 1A:1B mix ratio and low viscosity for effortless mixing and pouring. With a working time of approximately 13 minutes at room temperature, handling time of 6 hours, and overnight curing, you can rely on this no-odor system to deliver exceptional results. The translucent material can be easily colored with SO-Strong or Ignite colorants, making it perfect for a variety of applications.

From creating short-run molds for casting concrete and resins to producing concrete stamping pads, rubber mechanical parts, coating fabrics, and pour-in-place gaskets for industrial equipment and burial vaults, Econ 80 is the ideal choice. To ensure optimal results, it's essential to follow proper preparation, mixing, and pouring techniques. Store and use at room temperature, maintain low environmental humidity, and ensure good ventilation to minimize the risk of air bubbles and contamination.

For optimal adhesion, seal porous surfaces with SuperSeal or One Step sealers, and metal, glass, hard plastics, and sulfur-free clays require only a release agent. Don't compromise on quality - use Universal Mold Release for effortless demolding. To prevent air bubbles, vacuum degassing is recommended, and for a bubble-free finish, consider using a pressure casting technique.

With Econ 80, you can achieve exceptional physical properties and performance. Post-curing the rubber at 150°F (65°C) for 4 to 8 hours will further enhance its durability and toughness. Whether you're a seasoned professional or just starting out, this versatile material is perfect for a wide range of applications. Trust Smooth-On's reputation for excellence and discover the benefits of Econ 80 for yourself.
