why The Glue bond is improtant for Coated abrasives

In glue bond of coated abrasives are still used to polishing for some workpieces.  This is because animal hide glue is used for both the maker and sizer adhesives coats. The glue may be used alone or with an inert filler or extender. For this reason is that animal glue has a tendency to soften from the normal heat of grinding, glue bond products usually produce a more uniform,less harsh finish , in the case of fine grits can be easily buffed out. In my view, although they conform well and produce a superior finish, they lack the shed resistance ,durability and stock removal potential of resin bond products.
