9.7 COATED FABRICS

Vulcabond KB, MDX, and VP are suggested as adhesion promoters for coating formula-
tion for synthetic fabrics (polyamide, polyester). PVC coating does not have adhesion to
synthetic substrates used for the production of technical textiles, tarpaulins, conveyor
belts, etc. The isocyanurate trimer is the active substance in adhesion promoter, usually
mixed with a plasticizer such as dibutyl or dinonyl phthalate.
Epoxysilanes are preferred adhesion promoters in the production of coated fabrics
1
for airbags. Usually, two layers are coated: antiblocking surface layer containing polytet-
rafluoroethylene and base coating which has to adhere to polyamide fabric and it is com-

posed of polyurethane and PVC. This layer contains an adhesion promoter.
