Glue bond systems use animal hide glues, alone and with fillers. Glue bonds are not as resistant to heat as resin bonds, but do give a finish almost one full grit size finer than resin bonds. Glue Bonds are more flexible than Resin Bonds.

Resin Bonds offer greater resistance to heat, and are more durable in heavy stock removal applications, and provide the best all-around bond system. Resin bonds have a tendency to provide a harsher, more scratchy finish in fine grits and is more difficult to polish out.
