What is Bisphenol F Epoxy Resin CAS 9003-36-5?

CAS 9003-36-5 identifies bisphenol F epoxy resin, also called BPF epoxy resin or the diglycidyl ether of bisphenol F. It is made from bisphenol F and epichlorohydrin and is supplied as a light yellow to colorless liquid with lower viscosity than many bisphenol A epoxy resins.

What does the epoxy equivalent weight of 160-175 g/eq indicate?

Epoxy equivalent weight is the mass of resin that contains one gram-equivalent of epoxide groups. A range of 160-175 g/eq shows a relatively high concentration of reactive epoxide groups, which supports efficient curing and helps form a dense cross-linked network.

Which applications are suitable for this low-viscosity BPF epoxy resin?

It is used in solvent-free and high-solids anti-corrosion coatings, civil engineering repair mortars, industrial flooring, and structural adhesives. Its low viscosity also makes it suitable for electronic potting, casting, encapsulation, FRP, and carbon-fiber composites.

How should Bisphenol F Epoxy Resin CAS 9003-36-5 be stored and handled?

Store it tightly sealed in the original container in a cool, dry, ventilated area, ideally around 15-25 degrees C. Low-temperature storage helps avoid viscosity increase and spontaneous crystallization, while gloves, goggles, protective clothing, and adequate ventilation are recommended during handling.

Bisphenol F Epoxy Resin CAS 9003-36-5

Bisphenol F Epoxy Resin (CAS 9003-36-5) is a low-viscosity thermosetting liquid polymer synthesized via the polycondensation of bisphenol F and epichlorohydrin, serving as a critical foundational matrix within the broader category of Construction and coating chemicals. Operating as a highly reactive structural binder, this unmodified BPF epoxy exhibits superior chemical resistance and elevated cross-linking density compared to standard bisphenol-A alternatives, making the DGEBF polymer integral to formulating solvent-free heavy-duty anti-corrosion systems, while the bisphenol-F diglycidyl ether structure ensures exceptional mechanical performance in structural marine composites. Its compact molecular structure provides excellent substrate wetting and durability when deployed as a base epoxy phenol novolac resin in demanding industrial potting and civil engineering processing environments. To support continuous large-scale formulation schedules, our facility maintains extensive bulk supply capabilities, ensuring consistent batch-to-batch epoxy equivalent weights with customized specifications to meet precise rheological parameters, all backed by competitive factory pricing and comprehensive technical documentation including MSDS, TDS, COA.

Applications:

Anti-Corrosion Coatings: Functions as the primary low-viscosity matrix for formulating high-solids and solvent-free protective marine and pipeline coatings, providing exceptional resistance to aggressive inorganic acids and alkaline environments.
Civil Engineering & Adhesives: Utilized as a highly penetrative structural binder in concrete repair mortars, industrial flooring systems, and heavy-duty structural adhesives due to its superior substrate wetting capabilities.
Electronic Potting & Encapsulation: Applied in the formulation of electronic casting compounds where tight dimensional stability, low thermal shrinkage, and excellent dielectric properties are critical for component protection.

For applications specified with conventional bisphenol A epoxy grades, Epoxy Resin (Bisphenol A) is a separate epoxy family that should be selected by equivalent weight and viscosity.

Storage & Safety:

Storage Conditions: Store in tightly sealed, original containers within a cool, dry, and well-ventilated warehouse environment. Maintain ambient storage temperatures between 15°C and 25°C to prevent unwanted viscosity increases and mitigate the risk of spontaneous crystallization.
Safety & Handling: This liquid polymer is a known dermal sensitizer. Industrial handling requires proper local exhaust ventilation. Operators must utilize chemical-resistant nitrile gloves, splash-proof safety goggles, and protective work clothing to prevent dermal contact and mechanical eye irritation.

Quality Assurance:

Our chemical manufacturing facility enforces rigorous quality control protocols aligned with ISO 9001 industrial standards. Every production batch is subjected to stringent laboratory analysis, utilizing automated potentiometric titration to precisely quantify the Epoxy Equivalent Weight (EEW) and hydrolyzable chlorine content. We maintain strict, continuous monitoring of viscosity parameters via rotational viscometry to guarantee that the processing stability and curing kinetics of the polymer matrix comply fully with international composite manufacturing specifications.
