Coatings for Steel Foundries

Our products allow to deliver excellence at the highest possible level of operational efficiency.  The range of products have been specifically engineered so that they can be applied by dipping, flow coating, brushing, swabbing and spraying.

Coatings for Sand Moulds and Cores

The high casting temperatures associated with steel foundries requires careful selection of refractory materials, to ensure full protection against metal penetration and burn-on defects.
The range of coatings utilise high purity zirconium silicate or metal oxide refractories to offer protection under the most extreme casting conditions.
A full range of specialist products is also available to cover specific applications, such as the high demands of manganese steel, highly alloyed stainless steels or metal penetration due to hot spots or high metallostatic pressures.

Equipment

Intelligent Coating Unit

The ICU (Intelligent Coating Unit) automates the coating preparation from its as supplied state to the density that delivers the most consistent layer thickness – continuous monitoring, control and adjustment ensures optimized coating performance utilization. The ICU is ready for Industry 4.0 standards.

Flow coating equipment

The equipment consists of three main parts: the pressure tank, the control box and the catchment tray.  It operates on the principle of displacement of the coating from the tank via a flexible hose by use of low pressure compressed air.
No other power source is required and the low degree of wear due to the absence of mechanically moving parts in contact with the coating is of special advantage.

Electrostatic Coatings

TRIBONOL is 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.

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 of the polystyrene pattern. Permeability and composition have been specifically designed to meet the requirements of lost foam.

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.

CERAMOL 58/1 is a water-based refractory zircon coating, suitable for the production of rolls.
