Polytek EasyFlo FR Low-Viscosity, Fast-Curing, Liquid Polyurethane Plastics
Categories: Polymer; Thermoset; Rubber or Thermoset Elastomer (TSE)

Material Notes: Description: EasyFlo Series Liquid Plastics are excellent for casting decorative objects, sculpture reproductions, production parts, tools, models, duplicate masters and more. EasyFlo are mercury-free systems that consist of two parts (A and B) that, after mixing, quickly cure to tough polyurethane plastics. Since Parts A and B are super-low viscosity liquids, they are easy to mix, provide excellent detail penetration, and make bubble-free castings without vacuum degassing or pressure casting techniques. Rapid demold times make EasyFlo ideal for high-volume, fast-cast applications. All EasyFlo products can be easily color-cast, painted or machined. Most EasyFlo products can be filled for various cold-cast techniques such as cold-cast bronze, marble, etc. Thin-walled castings made from EasyFlo have surprising strength and lack the brittleness typical of other low viscosity, fast polyurethane resins.

Product Line Features:

  • Easy 1A:1B mix ratios, by volume
  • Very low viscosities
  • Rapid demold
  • Reproduces finest detail
  • Tough, non-brittle formulas
  • Excellent bubble release
  • Reduced need for pressure or vacuum
  • Pourable & sprayable versions
