Abstract
An abrasive article comprising abrasive grains, a
porous support material and a resin bond including a
coupling agent for coating said abrasive grains and said
support material, said resin bond being adhered to the
grains and support material with the aid of said coupling
agent, the coupling agent being compatible with the resin
bond, said resin bond yielding little or no volatiles during its
curing so as to effect the bonding and being cured under
conditions to limit production of volatiles so as to maintain
the amount of interchannel porosity to less than 14% of the
total volume of the abrasive article, the porosity of the
article being essentially determined by said support
material, whereby the article has dimensional stability
during cure and superior resistance to impregnation with
water after being cured. The support material may include
hollow bodies, such as microbubbles of glass or alumina or
the like, and the support material is used in an amount that
is carefully controlled to produce the desired porosity in the
abrasive article. A wide range of controlled porosity levels
in the respective grinding wheels produced may be
accomplished resulting in the production of wheels having
superior wet strength and dimensional stability.
