BENTOPRO-A is an excellent bentonite binder for preparation of sand mould for casting iron (grey, ductile, vermicular iron), steel and some non-ferrous metals. BENTOPRO-A is produced by careful activation of bentonite containing active mineral montmorillonite in the percentage of 80-90%, which is then converted through optimal drying and micronization process into a fine powder of uniform granulation.

BENTOPRO-A is characterized by excellent binding properties, good thermal stability and stable quality. It can be used on different lines for preparation of sand mould and casting, including the highly automated production lines.

Some of the expected effects of using BENTOPRO-A are:

• Improved casting surface
• High dimensional precision
• Decreased level of casting defects and scrap rates
• Improved cost-effectiveness of casting process
