Ester Cured Alkaline Phenolic Resin binder system consists of two parts: Part I Alkaline Phenolic Resin, Part II Organic Ester Curing Agent.
Characteristics
This binder system doesn’t contain harmful foundry elements: Nitrogen, Sulfur, Phosphorus, etc., which is especially suitable for the production of steel alloys, carbon steel and ductile iron castings.
The binder system has second curing under high temperature and good thermo plasticity, which can reduce hot crack, veining, defects of steel and ductile iron casting, as well as improve the dimensional accuracy of the castings.
It produces very less harmful and irritant gas, and improves the working environment greatly.

How to use
Choose different curing agent of XYG series according to different room temperature and sand temperature, adjust the addition rate of the curing agent (20-30% of the resin).
Add the curing agent into the sand and mix it evenly, then add XY-201 alkaline phenolic resin (1.2-2% of sand) and mix it for another 1-2 minutes, based on evenly mixed quantity.
When the mixture preparation is finished, make the core or the mold immediately to keep the mixture from stiffening, worse fluidity and finally fail to use.
Packing and Storage
Pack in iron drum with 230kg net weight or IBC tank with 1000kg to 1200kg net weight.
