HF9200 is a reactive epoxy furan resin, available in a two-component system. HF9200A is the resin component, and HF9200B is the hardener component. The HF9200 resin is an improved version of the commonly used epoxy/furan resin (70/30) base. It does not simply physically mix the epoxy and furan resins; the hardener is also specially processed. When the A and B components are mixed, a variety of compositions can participate in the cross-linking reaction. The mixing ratio for components A and B is 100:20-25.

Features and Applications
The HF9200 resin combines the benefits of both epoxy and furan resins, such as excellent resistance to acids and alkalis; higher temperature resistance than epoxy resins; improved brittleness of epoxy and furan; low viscosity, strong penetration, faster curing speed than commonly used self-mixed materials, and improved curing properties on damp surfaces; factory-produced, two-component supply, simplified mixing, easy to use, and有利于 ensuring the quality of construction work.
HF9200 resin is suitable for making heavy-duty anticorrosive coatings, used for equipment inner walls or concrete surface protection against corrosion; it can also be used to produce resin mortar and砂浆 for corrosion-resistant flooring and brick or plate lining, suitable for environments with alternating acid and alkali.
The HF9200 resin can be cured at room temperature, and heating treatment (80℃-120℃) is recommended for better results if conditions permit.
HF9200 Epoxy Furan Resin has a high operating temperature of 120°C, but please note that the temperature can vary depending on the medium. For use at higher temperatures, further inquiry or testing is required to confirm.

Please note:HF9200 resin must be used with our factory's A and B components. No additional thinner is allowed for HF9200 resin.
Storage and Packaging
HF9200A and B have a shelf life of one year. The viscosity remains largely unchanged after one year and can still be used. Store in a cool place and avoid contact with open flame.
HF9200 comes in 200kg iron drums.
