Cobalt boron acylate, named Manobond C-16, supplied by
Rhodea, England is the well-known adhesion promoter, used in
this study. Kaolin Modified Resin (KMR) is the adhesion promoter
prepared via the reaction of acrylonitrile and a crosslinking agent
to form a resin. The resin-iron complex was formed through the
drop wise addition of FeCl3dissolved in acetone to the resin. The
resin-iron complex was obtained by allowing it to cool. It was
decanted, filtered, washed with acetone, then dried and milled
into a fine powder. After that, kaolin was mixed with resin-iron
chelate in a ratio of 2:1, respectively. The structure of the kaolin
modified resin is shown inFig. 1 [25]
