ZIRCOTE - ZR - Zircon Base Coating
Zircote is high zircon content water base coating exhibiting thixotropic property preventing zircon precipitation. It has good adhesion characteristic and is self drying so it can be used on all sand systems foundry moulds and no-bake cores.
Benefits
- Protects sand system against high temperature and prevents penetrative action and scouring effect of molten metal thereby ensuring that the castings have smooth finish.
- Adheres well to the substrate, gives good coverage and does not peel off.
- Without dilution it flows freely on application of little pressure as by a brush or a foam roller.
- Extends life of Refrac shapes when coated with zircote.
- Can be used to coat ferrous viz. Plungers, skimmers etc.to prevent iron pickup by the metal.
Application
- Clean the surface and apply with a brush or a roller.
- For dipping or spraying, Zircote should be diluted with water.
