For the elimination of surface defects providing superior casting finish
Product information
SAND VITA is forming ultrathin film with low oxygen permeability and having strong adhesion on foundry sand surface. Ultrathin film of polymeric compounds is formed, which provides a protective barrier between the molten metal and the mould or core substrate during the casting process, and ensures the integrity of the as cast surface.
Sand Vita is Water-based coatings with superior spray and dipping properties, designed specifically to meet the demanding requirements of the production of iron foundry.
The usage of SAND VITA is small. For example, when produced 2,000 tons of castings, estimated 100kg of Sand Vita is sprayed
Specialist coatings
- Lost foam and full mould processes
- Spun pipe production
- The enhancement of metallurgical properties
- The protection of refractories and metal tools
Defect prevention SAND VITA is designed to deposit the correct coating structure onto a given substrate, to ensure cast surface integrity and help in the reduction and elimination of a number of casting defects:
*MOULD EROSION
*POOR CASTING STRIP
*GAS DEFECTS
*SAND EXPANSION DEFECTS
*METAL PENETRATION
*METAL/MOULD REACTIONS
*SCABBING DEFECTS
*METALLURGICAL DEFECTS
How to use 1. Spray with the AIRGUN spray over the surface of sand mold or core.
2. There is no fixed volume but if the spray covers the surface, it is enough.
3. Sand Vita will coat the sand mold or core surface, which prevent dehydration of the sand and make the sand surface smooth.
4. In result, the casting surface will be smooth.
