Cast Clean® inorganic foundry binder systems
A family of inorganic binders and catalysts designed to improve environmental performance without sacrificing casting quality or productivity.
Two components. One application-specific system.
Cast Clean systems typically consist of a Cast Clean Binder and a Cast Clean Catalyst. We manufacture a range of formulations, matching the combination to your foundry’s materials, equipment, and process requirements rather than offering a one-size-fits-all product.
Cast Clean Binder
The inorganic bonding component holds foundry sand together to form molds and cores. Modified silicate chemistry provides an alternative to organic resin-based binders.
Cast Clean Catalyst
The catalyst is selected with the binder to support your curing process, work time, strip time, and production goals. Our technical team recommends the appropriate combination after reviewing your application.
From no-bake molds to gas-cured cores.
The Cast Clean family includes inorganic no-bake binder systems and formulations suited to gas, heat, and microwave curing. Catalyst selection allows work and strip times to be tailored to process requirements. The exact capabilities depend on the selected system.
Versatility where it matters.
Metals
Our product literature describes applications in stainless steel, ductile and gray iron, high-alloyed iron, magnesium, brass, bronze, and aluminum.
Foundry sands
Compatible aggregates include silica, olivine, zircon, chromite, and ceramic sands. Sand quality, grain shape, moisture, and temperature all influence binder demand and final performance.
Casting quality and environmental performance.
Cast Clean systems are designed for rapid strength development, effective bonding, and post-casting breakdown. Properly prepared modified silicate molds and cores can help address binder-related veining, carbon pickup, and gas defects.
The product literature reports reduced organic binder-related VOC emissions and odor. Cast Clean binders are described as containing no phenol, formaldehyde, isocyanates, naphtha compounds, urethane, furan, or methyl formate. Review the safety data for the specific formulation and assess emissions across your complete process.
Make reclamation part of the conversation.
Dry sand reclamation and reuse are important parts of the Cast Clean approach. Our team can help evaluate reclaim quality, binder levels, shakeout, and the practical requirements for incorporating reclaimed sand into your process.
A few things worth knowing.
Why does Cast Clean use both a binder and a catalyst?
A Cast Clean system typically pairs a binder with a catalyst suited to the application. In a no-bake process, the binder and catalyst react after mixing with sand to develop mold or core strength. They should be selected as a system because the curing process and required work and strip times influence the appropriate combination.
Which metals can be cast with Cast Clean?
The Cast Clean product literature describes applications in stainless steel, ductile and gray iron, high-alloyed iron, magnesium, brass, bronze, and aluminum. J.B. DeVenne evaluates the binder and catalyst combination for each application.
Which foundry sands are compatible?
Cast Clean systems are compatible with common foundry sands, including silica, olivine, zircon, chromite, and ceramic aggregates. Sand analysis helps determine the appropriate formulation and process settings.
Does Cast Clean support inorganic no-bake processes?
Yes. The Cast Clean family includes inorganic no-bake systems with catalyst options for different work and strip time requirements. Gas, heat, and microwave curing options are also described in J.B. DeVenne’s product literature. The suitable process depends on the selected formulation.
Can an inorganic binder be used for both sand molds and cores?
Yes. Cast Clean product literature describes inorganic binder systems for both molds and cores. The appropriate system depends on the sand, alloy, curing method, handling requirements, and casting process. A system suitable for one mold or core application should not be assumed to suit every other application without evaluation.
Does Cast Clean contain phenol, formaldehyde, isocyanates, or furan?
J.B. DeVenne’s published FAQ states that its binders do not contain phenol, formaldehyde, isocyanates, or furan. Request the current safety data sheet for the specific binder and catalyst under consideration. Product composition information does not replace an assessment of workplace exposure or other materials used in the foundry.
