Product Description

Product description

Phenol Formaldehyde Resin F3620-2 is produced by condensing a molar excess of phenol to formaldehyde in the presence of an acid catalyst. This produces a thermoplastic resin. To cure this resin, a hardening agent is used, HMTA (or hexa). Under heat and pressure, it yields ammonia and formaldehyde as methylene groups to cure the resin, hence the term “two-step,” because of the two formaldehyde additions. A novolak phenolic resin has an infinite shelf life under normal storage conditions.Cured phenolic resin provides the rigidity necessary to maintain structural integrity and dimensional stability even under severe conditions.

Application

Phenol Formaldehyde Resin F3620-2 is recommended for Grinding Wheels.

Powdered resin is used as the principal resin binder for grinding wheels.Powdered phenolic resin affects the degree of wetting during mixing, the strength after molding, the flow and the degree of cross-link density at curing, and helps determine abrasive properties, strength, and heat resistance.The performance of powdered phenolic resin is roughly determined by the molecular weight, which directly influences flow, hexamine content, and particlesize . The wide range of powdered phenolic resins available can produce an equally wide range of grinding wheels and customer needs.
