INTRODUCING KALTHARZ 8500: THE MODERN HYBRID BINDER REDEFINING NO-BAKE CASTING.
In a foundry landscape that’s under increasing pressure to balance quality, cost, and sustainability,
DZanetech introduces a binder system that does more than just bind—it transforms.
Meet Kaltharz 8500: a modern hybrid binder system engineered to meet today’s casting demands with tomorrow’s performance standards.
As industries evolve, so too must the materials and technologies that support them. The Kaltharz 8500 system is a response to real-world needs—
offering high-performance casting results, low emissions, excellent reclamation compatibility, and cost-saving advantages across ferrous
and non-ferrous applications.

WHY THE WORLD NEEDS A BETTER BINDER.
Global foundry trends continue to shift toward ecological responsibility, economic efficiency, and versatile performance—
especially in sectors like mechanical engineering, automotive, mining, marine, and shipbuilding. Yet traditional furan-based no-bake systems,
while reliable, are increasingly limited by:
High free sulfuric acid content.
Elevated furfuryl alcohol (FA) levels.
Emissions and labeling concerns.
Costly resin and coating dependencies.
Foundries are searching for a better way—and Kaltharz 8500 delivers.
THE TECHNOLOGY BEHIND IT.
Unlike traditional furan binders which rely on strong acid activators to achieve curing, Kaltharz 8500 uses a chemically modified resin structure.
This structure—referred to as PR Furan or Hybrid FR/PR—enables the binder itself to carry much of the curing responsibility.
This innovation reduces dependence on strong acids like H₂SO₄ and phosphoric acid, ensures greater stability across temperature variations,
simplifies handling, storage, and safety compliance. Validated through MALDI-TOF and 13C NMR spectroscopy, these hybrid polymers represent
the forefront of innovation in foundry chemical technology.

EMISSION REDUCTION WITH REAL RESULTS.
In controlled comparisons between standard systems and Kaltharz-based systems:
SO₂ and sulphur emissions dropped drastically, casting skin degeneration reduced from 500μm to just 100μm and Zircon coatings were replaced
with more economical aluminum silicate without quality loss. This isn’t just cleaner casting—it’s smarter casting.
Kalthardz is already used in over 20 foundries across Germany, Turkey, Spain, Romania, Czech Republic, Australia, and expanding into India and Asia.
There is 3,500 tonnes annual sales volume across HA Group. Wherever modern casting is heading, Kaltharz is already there.
A NEW PERSPECTIVE FOR MODERN FOUNDRIES.
The industry no longer equates high FA with high performance. With Kaltharz, the quality equation has evolved:
Hybrid resins = high quality molds = high productivity = better castings
Kaltharz 8500 is not just an alternative. It’s an upgrade—a technology-driven resin offering tailor-made flexibility,
low environmental impact, fewer health and labeling concerns
