Molding Materials
The ECOLOTEC process offers a unique combination of environmental, metallurgical and productivity advantages, unmatched by any other high-production coremaking process. In the patented ECOLOTEC process, a water-soluble alkaline phenolic resin is mixed with sand and then hardened by gassing with carbon dioxide (CO2). ECOLOTEC bonded cores demonstrate outstanding thermal properties and provide excellent casting quality on all alloys.
ECOLOTEC binders are extremely clean, non-flammable water-based systems, that require no scrubber system during coremaking or casting. Odor, fume and VOC emissions at coremaking, pouring and shakeout are significantly lower than with most other foundry resin processes. The absence of sulfur, nitrogen or phosphorous in ECOLOTEC binders ensures free from casting defects associated with these elements. In addition the potential for carbon pick-up is negligible. The level of free phenol and free formaldehyde in ECOLOTEC binders is very low compared to other resin systems.
