The FENOTEC alkaline phenolic cold set resin process is a two part sand binder system based on a water soluble alkaline resin solution and a range of organic aliphatic hardeners. These hardeners provide a comprehensive range of reaction times.

FENOTEC can be used for the production of a wide range of castings in a ide range of alloys. Suitable for both cores and moulds, resin additions are ypically 1.0 to 1.5% with an optimum ester addition between 18 and 25% f the resin content. FENOTEC can be used in conjunction with a clean dry ilica sand (AFS 30 - 100). Chromite, Zircon and Olivine sands can also be sed successfully.

FENOTEC is fully adaptable to all mixing methods particularly to high speed continuous mixers. Batch mixers can be used but an allowance should be made for extended mixing time when selecting the required ester hardener. Several key development programs have resulted in a range of FENOTEC resin and ester formulations which allow high levels of sand reclamation to be achieved. Foundries are now benefiting from this new technology in terms of consistent high mould strengths, excellent breakdown after casting and improved casting finish.
