A safer, cleaner way to protect every mould
Water Based Refractory Coatings are applied as a thin, uniform layer on the mould or core surface to create a barrier between molten metal and the sand aggregate. Suspended refractory fillers — zircon, graphite, alumino-silicate or blends of these — form a heat-resistant skin once the coating dries, preventing metal penetration, sand burn-on and veining defects while giving the finished casting a smoother, cleaner surface.
Being water-based rather than solvent- or alcohol-based, these coatings are non-flammable, low-odor and safer to store and apply, without compromising on refractoriness or coverage. At BR Chemicals, every batch is tested in-house for density, viscosity and suspension stability before dispatch.
Built for a cleaner, safer moulding floor
A water-based system chosen wherever fire risk, fumes and casting surface quality all matter together.
Non-Flammable
No solvent or alcohol base means no flash-off flame risk during application, drying or storage.
Smooth Casting Finish
Fine refractory particles form an even barrier layer, reducing surface roughness and rework.
Excellent Suspension Stability
Formulated to stay in suspension with minimal settling, so density stays consistent from first dip to last.
Dip, Spray or Flow-Coat
Works across common application methods, with drying by air or low-temperature oven.
Choose Your Water Based Coating
Each coating family is built around a different refractory filler, matched to the alloy and casting finish you need.
Zircon Based Coatings
Zircon-filled coating for maximum refractoriness and a fine, defect-free finish on steel and iron castings.
Zircon-Graphite Based Coating
A blended zircon-graphite system combining high heat resistance with excellent mould release properties.
Graphite Based Coating
Graphite-based coating ideal for grey iron and SG iron castings, reducing sand burn-on and improving finish.
Alumino-Silicate Based Coatings
An economical, general-purpose refractory coating suited to a wide range of ferrous casting applications.
