NOVELTY - A racket wire coating comprises 55-75 pts. wt. polyurethane resin, 10-20 pts. wt. graphene resin, and 10-15 pts. wt. cellulose acetate butyrate. USE - Racket wire coating. ADVANTAGE - The coating contains graphene resin and cellulose acetate butyrate that produces chemical reaction during bonding process which increases surface activity of polyurethane resin, thus increases surface softness of ball mesh wire without reducing wear resistance and friction and makes it more flexible to improve competitive level of athletes. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a racket comprising wire-shaped racket wire coated with inner coating and outer coating.
