Mould & Core Coatings



Mould & Core Coatings are used in foundry to provide smooth surface on steel and iron casting body. It is available with various bases like Zircon, Graphite, Magnesite and Aluminium silicate with water and solvent as a carrier. We are selling this product under trade name METACOTETM.



When coating is applied on mould and core surface either by brushing, spraying, flooding, swabbing or dipping, it fills the gap or pores between the sand particles and provides an impermeable refractory surface as well as an inert layer between metal and sand. To avoid sand fusion and metal penetration a proper coating thickness should be applied on mould and core surface, for this a number of thin coats may be required and it should be properly dried before pouring of metal to avoid the pin/blow holes in the castings.



METACOTETM is available in Zircon, Graphite, Magnesite & Aluminium Silicate bases with Water and Alcohol/Solvent as a carrier. METACOTETM is available in various physical forms like powder, paste and ready to use form for lost foam and all conventional moulding process. It is packed in polythene lined bags, HDPE buckets and tin buckets.



  • • Excellent flow characteristics
  • • Low foaming and good suspension properties
  • • High refractoriness as the METACOTETM mould and core coatings provides exceptional resistance to fusion and penetration defects
  • • Easily curable on flaming off, free from wet patches • No tendency to cracking or scaling on drying
  • • Provides smooth surface finish of the castings



METACOTETM has excellent flow characteristics, good suspension quality and high refractoriness. The baume/visocity/specific gravity needed for the METACOTETM mould and core coatings are maintained as per customer’s requirement.
