Evaluation of fatty vinyl ether polymers and styrenated polymers for metal coatings

Résumé fourni par la source

Abstract A further evaluation of fatty vinyl ether poly‐mers as potential coatings for metals (particu‐larly cans) includes studies on 12 linseed and soy‐bean polymers containing isobutyl vinyl ether and cyclopentadiene. Baked films with and with‐out driers from these homo‐, co‐, and terpolymers and their styrenated derivatives were examined for flexibility, adhesion, chemical resistance and hardness. Film properties were related to chemi‐cal composition of the polymers, including the effect of styrenation, linseed vs. soybean polymers and content of cyclopentadiene. Films possessed excellent flexibility, adhesion and hardness. Sur‐prisingly, for most polymers, the hardest films were obtained without driers.
