These polyurethane liquid mold rubbers are soft to mid-range hardness, room temperature curing systems offering excellent flexibility for molds to be made of highly detailed, undercut and complex sculptural models.

The 72 Series liquid mold rubbers are supplied as pourable liquids so poured block and blanket molds can be made with ease. In addition, these rubbers can be thickened to a user-controlled thixotropic consistency for brush-on mold applications with a liquid thickening agent. Poly 72 Series rubbers are available in standard and mercury free formulations for art foundry, sculptural and figurative mold making applications. As with other Polytek mold rubbers, these systems can also be used for hobby, craft, prop and display mold making and casting projects.

Note: These rubbers may soften over a period of two or more years and may damage lacquered or painted surfaces that come in contact with the 72 Series rubber.
