Polytek 74-30 Clear Flexible, High-Strength, Polyurethane Mold Rubbers
Categories: Polymer; Thermoset; Rubber or Thermoset Elastomer (TSE)

Material Notes: Description: Poly 74-Series Liquid Rubbers consist of two parts (A and B), which, after mixing, cure at room temperature to flexible, high-strength, mold rubbers. Poly 74-Series Rubbers make durable, easy-releasing molds for casting plasters and waxes without release agents. When Poly 74-Series molds are properly prepared, they are also excellent for casting concrete and various resins, such as epoxy, polyester, polyurethane and acrylic.

Product Line Features:

  • Make durable, long-lasting molds owing to strength and elongation properties of cured rubber
  • Pourable liquid rubbers that cure to soft to mid-range hardnesses
  • Easily thickened for brush-on applications
  • No release agents needed when casting many plasters, waxes and concretes
  • Low-viscosity liquid rubbers capture detail from intricate masters
