8.28 RUBBER

Many commercial adhesion promoters can be used in rubber, including Actimax,
Chartwell, Chartsil, Cofill, Cohedur, Dow Corning, Dynasylan, Eastman, Ekaland, Genio-
sil, Markoba, Regalite, Resalloy, Silquest, and Xiameter. There are too many products to
be listed by their grade names here but a full account of these additives can be found in
Databook of Adhesion Promoters which also contains additional information on the use of
these additives.
The adhesion between ethylene methyl acrylic rubber and the polyester fabric was
improved using resorcinol-formaldehyde-latex solution having high compatibility with
rubber and chloroprene rubber latex able to participate in the crosslinking reaction with
1
1
amine crosslinking agent. The adhesion was increased by over 40%.
The adhesion between hexamethoxymethylmelamine (HMMM)-containing rubber
compounds and brass-plated steel cords was studied to understand the role of HMMM in
2
2
adhesion promotion. Application of HMMM improved adhesion at elevated humidity.
The polybutadiene-modified epoxy rubber was used as an adhesion promoter for
3
coatings applied on the gold surface.
An adhesion promoter for a hot melt adhesive or a pressure sensitive adhesive was
4
prepared by admixing a hydrolytic silane compound with an aqueous buffer solution. The
adhesive is able to bind to very low surface free energy substrates, such as Xerographic
4
prints contaminated by silicone fuser oil.
