Furan resin is also called furan resin. It is a thermosetting resin with excellent chemical and heat resistance, and is mainly used as a corrosion-resistant lining or resin cement for joints. It is made by condensing furfuryl alcohol, obtained by reducing furfural, with formaldehyde. The black polymerization precursor obtained using toluenesulfonic acid as a catalyst is dissolved in a solvent and painted on the inside of a reaction vessel or tank, then baked.
