PROBOND

Our range of Bentonite which is processed in our Mills to enhance the swell and Bond properties of MPM BOND. The aim is to improve/shorten swell/gel times and to enhance bond capabilities of conventional Bentonite so that less quantity over current usage at the time is required for addition in the green sand to achieve standard/ current target GCS values of a foundry green sand system.

This in turn improves sand flowability, allows the sand to 'breathe' better by improving permeability, reduces dead clay and oolatization and maintains sand refractoriness; all essential to maintaining good green sand performance on castings and reducing related casting defects.
