- 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
