Bentonite sand modifier. Mollitia is a special additive for bentonite moulding sand, which contains organic polymers and inorganic compounds. Eliminates surface defects such as: veins, scabs, scars, bubbles, etc.
Moulding sands made with Mollitia has greatly reduced tendency to friability (flaking) and cracking. Green-sand moulds are characterized by greater flexibility, cohesion and better compatibility, and higher permeability up to 20%. Stabilizing and storing moisture for long time, the product improves mould thermal expansion. Allows for better knock-out properties in the final process stage. Addition of Mollitia can reduce the workload on the cleaning of castings and reduce the amount of broken moulds and foundry scrapers (failed castings).Just add to the circulating moulding sand, a small amount of Mollitia – typically 0.5 parts by weight. (0.3-0.7 parts by weight), then just refresh the 0.1 parts by weight. The experience of many foundries also shows that Mollitia makes it easier to separate the model from the complicated zones on the mould.
