Antifouling coating composition comprising furan compounds, method for protecting aquatic structures, and articles protected against fouling organisms
First Claim
1. A marine or freshwater antifoulant composition comprising a material selected from the group consisting of film-forming polymer, cementitious material, elastomeric material, and vulcanized rubber an amount of an antifouling agent admixed with said material and effective to be released from said material at an antifouling effective level, said antifouling agent selected from the group consisting of at least one furan compound of Formula I or II ##STR3## wherein R1, R2, R3, and R4 are independently selected from --C(O)R5, --C(O)OR6, (C1 -C8)alkyl, phenyl, phenyl substituted with (C1-C4)alkyl, (C1-C4)alkoxy, halogen, and hydrogen, provided that at least one of R1, R2, R3, and R4 is not hydrogen;
- R5 is R6 or NR7 R8 ;
R6 is (C1 -C8)alkyl, (C2 -C8)alkenyl, (C2 -C8) alkynyl, phenyl, phenyl substituted with (C1 -C4)alkyl, (C1 -C4)alkoxy, or halogen;
R7 and R8 are independently selected from hydrogen or R6.
