high temperature lost foam casting coating

详情

TONTEN TM LFC refractory coatings are made of aluminosilicate refractory mixed water, can be used to STMMA, EPS and PMMA foamed pattern for iron casting in LFC process(lost foam casting process).

TONTEN TM LFC refractory coatings are highly permeable refractory materials, it is suitable for grey iron and ductile iron castings.The coatings are in high viscosity with a special anti-mobility, this will make coating layer to be much smooth and strong, there will be no cracks and wrinkles because of movement after coating. The coating has a very wide water dilution, for manufacturers to find the best coating thickness to eliminate metal penetration and carbon-rich defects, to eliminate the surface cleaning problems.

Our coating material are made of aluminosilicate and andalusite as the main chemical components, it is refractory coating with high air permeability. It is mainly used for STMMA and EPS foam-pattern coating for iron and steel lost foam castings.

The coating has a high viscosity, with a special anti-flow performance, so that the coating is smooth and strong, the appearance of the coating layer after dipping will not be dripping and cracks or wrinkles; The coating also has a wide range for water dilution, can be found a best coatings thickness according to the requirements of various castings.
