1. Phenolic resin for foundry 2. Phenol formaldehyde resin 3. CAS No. 9003-35-4 4. Free samples Phenolic resin Phenolic resins are a two part Estercured phenolic binder system that uses an alkaline phenolic resin.   The ester coreactant controls the cure rate.  It is a brownred transparent liquid with the following characteristics1. The system contains no Nitrogen, Sulphur, or Phosphorous reducing the potential for casting porosity defects.2. The organic ester hardening systems high temperature thermoplastic and secondary cure further cross-links the polymer reducing hot cracking and veining of steel and ductile iron castings3. The process does not generate harmful, irritating, or noxious odors, significantly improving the work environment.4. Good collapsibility reduces workload for cleaning and improves work efficiency. SPECIFICATION Phenolic resinItemStandardAppearanceBrown red liquidViscosity, 25°C≤ 150 MPa.SFree Formaldehyde≤ 0.3%Density, g/cm3 20°C1.25± 0.05PH Value≥ 12Shelf life, ≤25°C12 monthApplicationSteel castings, ductile casting and non-ferrous casting  a. Mixing ProportionSand                              100Resin            &n...1.

They are better known however for the production of molded products including pool balls, laboratory countertops, and as coatings and adhesives. In the form of Bakelite, they are the earliest commercial synthetic resin.
