Low-cost Shore 80A polyurethane rubber with easy mixing and pouring.1A:1B mix ratioLow viscosityWorking time ~13 minHandling time ~6 hrOvernight cureTranslucent and tintable
This Shore 80A polyurethane rubber is designed for durable mold making and industrial components. It balances performance and cost-efficiency.
This is a more affordable and faster-curing option than our well-known PMC™-780. Its physical properties are lower than those of PMC™-780. The system is odorless, has a 1A:1B mixing ratio, and a low viscosity that allows for easy mixing and pouring. The working time at room temperature is approximately 13 minutes, with a handling time of 6 hours, and the rubber cures overnight. Econ™ 80 is translucent and can be easily tinted using SO-Strong™ or Ignite™ colorants. It is commonly used for producing short-run molds for casting concrete and resins, concrete stamping pads, rubber mechanical components, fabric coatings, pour-in-place gaskets for industrial machinery, and burial vaults. Important: To reduce air bubbles in the cured rubber, vacuum degassing is advised.
It captures fine detail without requiring vacuum degassing in most cases, making it suitable for both professional and hobbyist fabrication work.
Mix at a 1A:1B ratio by volume until uniform. Pour onto clean, dry surfaces. The low viscosity helps reduce bubbles without the need for degassing.
