It is light off coating for use on sand moulds and cores in the casting of Mangeanese steel. In coating moulds and cores, the most important requirement is to obtain an even coating over the metal/sand contact areas. This is best achieved by spraying but can also be obtained by brushing, swabbing and in the case of cores, by dipping. When spraying good dense delivery is best since fine spray is likely to suffer from premature evaporation of the thinner and deposit of an unsatisfactory coating. It is essential always to ensure that coating is well mixed and suspended before application.
