Application No. 08/867,617
rubber body against the epoxy resin-coated surface and heating
the rubber body and the epoxy resin-coated surface to a bond-
forming temperature and maintaining the pressure and temperature
for a time sufficient to form the bond.
This appealed subject matter is adequately illustrated by
independent claims 1 and 7 which reads as follows:
1. A method of forming a bond between a first bracket
member and a resilient rubber body containing at least 40 weight
percent of at least one of polyisoprene rubber or neoprene in a
vehicle mount comprising a first bracket member, a second
bracket member and said resilient rubber body sandwiched between
said bracket members, said method comprising
forming on a surface of at least one of said bracket
members
a coating of an epoxy resin cured at least to an immobile film
at room temperature,
chlorinating a surface of said rubber body provided that
said body does not inherently contain chlorine in the form of
neoprene rubber,
pressing said chlorinated surface against said epoxy resin-
coated surface, and
heating said rubber body and bracket to a bond-forming
temperature and maintaining said pressure and temperature for
a time sufficient to form said bond.
7. A method for forming a bond between a rubber body
containing at least 40 percent by weight of polyisoprene rubber
and
a surface of a body coated with an epoxy resin cured at least to
an immobile film at room temperature, said method comprising
