Most foundries accept bentonite inefficiency as a fact of life. MouldMax changes the equation.
The Problem Nobody Talks About
Every time you add bentonite to the mixer, a significant portion of it never fully hydrates during the mixing cycle. It requires more time to activate and may only reach proper hydration over multiple cycles — meaning you're paying for clay that isn't working when you need it most. The result: inconsistent mould hardness, free moisture causing spurting and blowholes, variable compactability across shifts, and bentonite bills that are higher than they should be.
Most foundries compensate by adding more bentonite, more water, or supplementary binders like dextrin. That treats the symptoms — but it doesn't fix incomplete activation. You end up spending more to get results your existing bentonite should already be delivering.
What MouldMax Does
MouldMax is a water-based catalyst added at just 0.5% of all water in your sand system. It works at the molecular level, promoting more efficient ion exchange between water and bentonite clay — making water a better activator without changing the water itself. It also enhances water's resistance to evaporation, so moisture stays available longer during moulding. Better water retention means better bentonite performance, which means better castings.
The effect is measurable within 24 hours: higher green compression strength at lower moisture levels, reduced free moisture, and more consistent compactability. Over time, you'll need 10-15% less bentonite because more of each kilogram is actually working. Dead clay decreases. Active clay increases.

Your Sand System: Without vs. With MouldMax
| What You Experience | Without MouldMax | With MouldMax |
|---|---|---|
| Bentonite Activation | Partial — bentonite requires more time to fully hydrate | Near-complete — more active clay per kg |
| Free Moisture | Common — causes spurting, blowholes | Minimized — better moisture retention |
| Mould Hardness | Inconsistent across shifts | Consistent and predictable |
| Bentonite Consumption | Baseline | 10-15% reduction |
| Compactability | Variable | Stable |
| Defect Rate (sand-related) | Industry average (3-5%) | Significant reduction |
| Supplementary Binders | Often needed (dextrin, etc.) | Typically eliminated |
| Time to Impact | — | 24 hours |
The simplest improvement you can make to your sand system.
Direct Savings with MouldMax
What Foundries Have Said
The magic of MouldMax seems to be happening at SVAPL too, our rejection has come down drastically from 4.5% to 1.45%
Mr. Ranganathan
MD of SVAPL Foundry, Gummudipoondi
On the first day itself we have seen that the peel off was better and the casting shine was very good. After using MouldMax, we have seen that all our sand related defects have completely disappeared. We have seen that our bentonite addition has reduced from 0.6% to 0.38%. For the same strength and reduced bentonite usage, the permeability has increased by 30 points and a reduction in dead-clay by 1.4% within just 10 days of using MouldMax.

Our mould leak problem has been eliminated completely. Our bentonite consumption has reduced by 20%.

Implementation Takes 10 Minutes
MouldMax is a non-hazardous liquid (pH 7.5-8.0), completely water-soluble. Connect a dosing pump to your water line, set it to 0.5%, and you're done. No equipment modifications, no formula changes, no trial period anxiety. Your water technician can handle the installation.
You don't change your sand, your bentonite, your carbon additive, or your process. You just make the water work harder. That's it. The catalyst does the rest.
