The Leader of Thermal Spray Coating

About Thermal coating

작업사진

Economical and widely applied high performance surface coating technology

Thermal Spray is, Coating technique, melting (or heated) materials such as metals or ceramic by electrical arc or fuel are sprayed and performed the coating layer onto a base metal surface

Benefit

·   No limitation of base materials.
    Ferrous, Non ferrous, Plastic, Stone, Ceramic, Etc.

·   No limitation of Substrate dimension

·   No size transformation during spraying

·   Available both Field and in-site Spray Coating

·   Thick Coating (Max. 5mm, recommend)

·   Various kinds of Coating Materials (about 200types)
