Mould and Core Dressings (Water base)

Acme range of water based dressings are specially developed for Iron and Steel foundries for Cold box, hot box and shell core systems. Dressings / coatings are meticulously formulated to impart freedom from drips, runs and no crack development on dried film layer. Coverage and adhesion are major properties to ensure ability to coat larger surface area. Application techniques by brushing, spraying, dipping and flow methods are major characteristics developed especially for use with medium and heavy section iron and steel castings.

SHELLCOAT range of water based ready for use coatings in liquid form are specially formulated for drip application for cold box, hot box and shell cores. A uniform layer of filler deposited by shellcoat range of coatings on the core surface ensures clean from free casting. These coatings are suitable for iron and steel castings.

SHELLCOAT–16: Graphite is used as filler. This product is used for shell & hot box cores in iron and non-ferrous foundries for dip or spray application.
