These are solvent or water based, fusion inhibiting, refractory coatings to be applied on mould walls or cores primarily to give good surface finish and consistent casting quality.
This is achieved by
Enabling better molten metal flow characteristics thus enabling better filling in intricate mould cavities
Preventing surface defects such as metal penetration, sand burn-on (fusion), carbon pick up, sand expansion defects (such as veining, rat tail, finning etc.) or lustrous carbon defect.
Preventing mould wall erosion and thus subsequent inclusions in molten metal
Improving stripping characteristics of castings
