lost foam coating
LFC coating paints
are special coatings used in the lost foam casting (LFC) process. These coatings are applied to the foam model to form a refractory barrier, whose main function is to isolate the casting from the molding sand, thereby ensuring the quality of the casting and reducing defects such as pores, broken sand, and burned sand in the casting, thereby greatly improving the yield rate of the casting.
The performances of LFC coating are mainly thermal performance and air permeability, which determine its role in the casting process.In practice, it is necessary to measure and control its viscosity, solid content, air permeability, PH value and so on.The quality of epc products can be guaranteed only when the performance of the coating is stable and consistent.
