RC 783: WATER CLEAR RIGID 82 SHORE D URETHANE CASTING SYSTEM

PRODUCT HIGHLIGHTS:

  • IExceptional clarity
  • Good exterior weatherability, non-yellowing, light stable product
  • Impact resistant
  • No odor
  • Improved viscosity for easier pouring
  • UV light and oxidation resistant
  • Water resistant

PRODUCT DESCRIPTION:

RC 783 is an impact resistant rigid 82 shore D material that is completely used to make clear or tinted castings of all kinds. When used
at room temperature, castings 1/8″ thick or larger can be readily cast. Castings that are less than 1/8″ thick generally require a mild post-cure.

TYPICAL PRODUCT USES:

  • Prototype computer types
  • Models of all kinds
  • Artwork components
  • Architectural models
  • Transportation cases
  • Miniatures and movie props
  • Good for outdoor and wet applications
