Application

Furfuryl alcohol resin serves as a versatile material primarily used in molding sand for cast metals like cast steel, cast iron, ductile iron, advanced alloys, and non-ferrous metal castings. This thermosetting resin containing furan rings is obtained through the polycondensation of furfuryl alcohol or furfural in the presence of strong acids. Known for its superior characteristics such as moderate viscosity, minimal shrinkage after curing, high bond strength, and excellent anti-corrosion properties, it also features a simple synthesis process with low production costs. With rapid curing times, low nitrogen content, and minimal free aldehyde levels, furfuryl alcohol resin is particularly effective in applications requiring strong adhesive properties, such as the anti-corrosion engineering of bonded granite found in sewage systems and foundry stone plants. Overall, it delivers significant technical and economic benefits.
