Cera-Fina is a carbon-free phosphate investment developed for professionals who demand a more finely grained investment. It is designed for use with all classes of casting alloys: precious, semiprecious, and non-precious.
Features:
- Extremely fine texture results in accurate castings with very smooth surfaces
- Extended working time, as much as 10 minutes, allows the investing of multiple flasks
- Absence of carbon assures compatibility with all casting alloys, especially Palladium and non-precious
- Increased liquid to powder ratio yields a creamier mix and allows better flow, resulting in bubble-free castings
*Suggested concentration of Special Liquid Concentrate is 75% (3 parts liquid to 1 part water).
