Bisphenol F epoxy resin
A lower-viscosity, crystallization-resistant cousin of BPA epoxy, favored for solvent-free floors and chemical-resistant linings.
Bisphenol F epoxy resins are made from bisphenol F (a mix of methylene-bridged phenol isomers) and epichlorohydrin. Typical liquid grades have an EEW of about 165–175 g/eq and much lower viscosity than standard BPA resin.
BPF resins are used in solvent-free and high-solids floor coatings, self-levelers, tank and secondary-containment linings and composites. They are often blended with BPA resin to cut viscosity and resist crystallization without reactive diluents.
Without BPA’s two methyl groups on the bridging carbon, BPF molecules are smaller and more flexible, lowering viscosity. Cured BPF networks typically offer slightly better solvent and chemical resistance than BPA equivalents. Like BPA resins, they are aromatic and not UV-stable.
Handle like other liquid epoxies: avoid skin contact, wear gloves and eye protection, and ventilate. Research also notes that bisphenol F is not automatically a safer substitute for BPA in health terms.
Blending lowers viscosity and reduces crystallization while keeping the cost and properties of BPA resin, often avoiding the need for reactive diluents.
Yes, it contains no bisphenol A, but bisphenol F has its own health and regulatory scrutiny, so it is not automatically a drop-in “safer” choice.
