8.8 POLYAMIDE

Many commercial adhesion promoters can be used in polyamides, including Geniosil,
Fusabond, Dynasylan, Eastman, Silquest, Priamine, Tyzor, and Resalloy. There are too
many products to be listed by their grades 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.
Adhesion promoter comprises an organotitanium compound (titanium IV isopropox-
ide (Vertec RJCE)), polyamide (Unirez 119; Unirez 138 Eurelon 975, Flexrez), and sol-
1
vent, for the use in the solvent-based liquid inks and coatings for flexible packaging.
The adhesion properties of aramid fibers are difficult to control in the production of
2
composites for tires and hoses. The fiber surface is very smooth and chemically inert. 2
The microwave-assisted surface-treatment using microwave radiation together with dry
reactive chemicals to create hierarchical structures on the fiber surface was investigated. 2
A thin carbon layer was deposited onto the fiber surface to make it more reactive to the
2
heat accumulation. Then the fibers were treated using ferrocene and graphite under con-
2
2
stant gas atmosphere. Adhesion strength was increased by 102-259%.
Organofunctional silanes (Z-6040 and CoatOsil 1770 silanes) are used as adhesion
promoters in the coating of polyamide fabric with silicone emulsion in the production of
3
material for airbags.
