Abstract:

The objective of this work was to develop coated fabrics with high adhesion between polymer and substrate to minimize delamination under severe climatic conditions and to provide high-component peel strength of heat-sealed seams. Polyether urethane was modified with olive drab pigment, UV light-absorbers and a silicone bubble-dispersing agent to improve the resistance to aging of coated surfaces. The pigment improved coating bond to the nylon substrate, heat-seal peel strength and resistance to 150 hours exposure in the Weather-Ometer. Application of multiple thin polymer coats successfully eliminated bubble formation during the coating application. Selected weapon accessory items were designed and fabricated with high-strength heat seals from the laboratory prepared material. P.S.-PL
