Metallurgical Coatings

A full range of specialist products is also available to cover specific applications, such as localised chill and grain refinement.

TELLURIT chill-promoting coatings for grey cast iron are ideal for producing a wear resistant surface.

MOLCO 50 dressings are designed for the localised densening of grey cast iron. It can eliminate the use of metal chills and is useful for treating heat centres affected by open grain that are difficult to feed.

Electrostatic Coatings

TRIBONOL are a range of mould and core coatings for electrostatic deposition. The electrostatic method of application circumvents problems of solvent vapour, flash hazard and lengthy oven drying. It is a totally dry process.

Mould and Core Hardening Coatings

HARDCOTE is a surface stabilizing coating for greensand moulds for casting of iron, steel and aluminium.  It is an air-drying water-based coating and is applied to greensand mould surfaces using conventional spray equipment. HARDCOTE prevents mould sand erosion and related casting defects.

Full Mould and Lost Foam Processes

The SEMCO perm and STYROMOL ranges of water based coatings are designed to promote excellent surface finish and dimensional stability whilst avoiding common problems such as lustrous carbon formation, metal penetration and premature mould collapse. Permeability and composition have been specifically designed to meet the requirements of lost foam. The coatings can be applied by spray, dipping or brush.

Spun Pipe and Rolls

SPUNCOTE are specialist products formulated to provide a permeable coating with very low gas evolution for the centrifugal casting process. They can also assist metal flow and promote easier stripping of the finished casting.

SEMCO ZIR 24PX is a water-based refractory zircon coating, suitable for the production of rolls.

Tools and Refractories

FRACTON coatings are used for protection of refractory surfaces, metal dies and launders, pig moulds and other metal tools.
