No-bake Alkaline Phenolic Resins
ALFANOL™
ALFANOL™ resins, in the brand registered Alkaline Phenolic Resins category, have been developed by R&D department as a result of experiments in many years.
ALFANOL™ resin, cured by ester-based catalysts without the addition of heat or gas, is suitable for all casting alloys. ALFANOL SERTER™ AS and ALFANOL SERTER™ AKS catalysts, created with ester-containing formulations designed for different operating temperatures, give opportunities to obtain the desired mold striping times under ambient conditions.
ALFANOL™ resins are water-based systems. The most important advantage of these systems are having less gas defect compared with solvent-based binder systems. We offer a wide range of products to our customers with ALFANOL™ resins with different types and properties.
Alkaline polymer chains structure, which has been brought to the best appropriate molecular structure to perform the optimum reaction with ester-based catalysts. As a result of this, the best bonding properties occur between the sand particles. The structure, which hardens by forming cross-links, shows neutral properties when the resin/hardener ratio is well adjusted. So this type of resin can be used for all castings, including aluminum casting.
No-bake alkaline phenolic resin is marketed international brand name ALFANOL™. Our R&D specialists provide technical support services for foundries, to achieve high-efficiency targets by researching customer demands and changes in production technologies that are being renewed.

Hardeners for No-bake Alkaline Phenolic Resins
ALFANOL SERTER™ AS – AKS
ALFANOL SERTER™ is high-performance ALFANOL™ resin hardeners containing high purity esters. There are various types of hardeners that offer flexibility in working and stripping times. The wide range of hardeners are designed for extraordinary climatic conditions. In this way, foundrymen around the world choose the best resin/hardener couple that suits the foundry conditions in their region. Sand molds reach high strength values with suitable hardeners at the desired time. Its flexible structure eliminates the possibility of waste during the mold stripping process.
The new generation ALFANOL™ resin hardeners, which have strengthened mechanical and chemical properties with performance additives compatible with esters, are produced in line with the renewed needs of the foundry.
