Most widely accepted adhesives for fastening of abrasive grains to the surface of a polishing wheel are
manufactured adhesives or cement compounds. They are replacing hide glues which, up to several
years ago, were considered the ideal adhesives for preparing polishing wheels in all grit sizes.
Polishing wheel cements are now formulated to give a wide range of viscosity's and flexibility, and can
be used with a wide range of abrasives and grit sizes.
If hide glue is to be used, it should be a high-grade material selected for jelly strength, melting point,
viscosity, and flexibility.
