Resins are as binders generally used are phenol formaldehyde resin (resol) glue, urea formaldehyde and epoxy resin. The type of backing, bond and abrasive grain dictates the application area of a coated abrasive product. For heavy applications a combination of sturdier backing, strong bond and bulkier and sharper abrasive grains are a necessity. More than the backing and abrasive grain, it is the adhesive bond which decider the life and performance of coated abrasive. The strong bond usually used is phenol resin. The demand for a better performing product necessitates the development of stronger resins. The various types of binders used for coated abrasives have been studied. The performance of phenolic resin made with this modified composition is analysed. This work thus forms a basis for the development of a better resin by modifying the existing composition. The synthesis and characterization of phenol formaldehyde resin as a binder used for coated abrasives was studied and found to be suitable for different applications in the industry.
