Product Description

STEELCOT MG **0

A Magnesite and spirit based dressing for moulds and cores during casting of Manganese steel.

DESCRIPTION

STEELCOT MG **0 is a basic refractory coating for moulds and cores during casting of Manganese steel. The moulds can be from silica, olivine, or chromate sand.

STEELCOT MG **0 contains high quality refractory dead burnt magnesite with the appropriate binders within Iso-propanol as solvent. This basic and refractory nature of STEELCOT MG **0 protects the mould from the aggressive attack of Manganese steel, giving a good surface finish of the casting.

INSTRUCTIONS FOR USE

STEELCOT MG **0 is supplied in a paste form and should be diluted with Iso-propanol solvent before use. The dilution ratio depends on the application procedure.

For brush application, a dilution with ****0% Iso-propanol is recommended. For spray applications, a dilution with *5% Iso-propanol is recommended.

After application the dressing should be ignited with a flame. To avoid solvent loss by evaporation, large moulds or cores should be dressed in small areas ignited individually.

Allow the coating to burn out and to cool to ambient temperature before closing and casting, or alternatively close and cast while still hot: avoid the intermediate situation.

ADVANTAGES

•High solids/ low gas content dressing, utilising ultra modern suspension and bonding techniques.

•Low gas evolution on casting, which reduces problems of gas entrapment, blowing, explosion penetration and oxide folding.

•Excellent brushability, even on multiple application on warm moulds, allowing easy and trouble free use.

•Gives an excellent surface finish and prevents surface defects in Manganese steel castings.
