Abstract
A method of controlling the attachment of organisms to an underwater surface is disclosed. The method comprises contacting the organisms with a compound of Formula I ##STR1## wherein R.sub.1, R.sub.2 and R.sub.3 are each independently hydrogen, C.sub.1 -C.sub.3 alkyl, C.sub.1 -C.sub.3 alkoxy, halogen, or hydroxyl. Antifouling coatings and cementitious compositions containing a compound of Formula I are also disclosed.
Claims28
An antifouling coating for an underwater surface which controls the attachment of organisms to that surface, said coating comprising
- (a) a compound of Formula I:
- ##STR3## wherein R.sub.1, R.sub.2 and R.sub.3 are each independently hydrogen, C.sub.1 -C.sub.3 alkyl, C.sub.1 -C.sub.3 alkoxy, halogen, or hydroxyl groups in an amount effective to control the attachment of barnacles to said surface;
- and
- (b) a film-forming component.
An anti-fouling cementitious composition comprising a cementitious matrix and a compound of Formula I ##STR4## wherein R.sub.1, R.sub.2 and R.sub.3 are each independently hydrogen, C.sub.1 -C.sub.3 alkyl, C.sub.1 -C.sub.3 alkoxy, halogen, or hydroxyl groups in an amount effective to control the attachment of barnacles to said composition.
A method of combatting the attachment of organisms to an underwater surface comprising contacting said organisms with a compound of Formula I:
- ##STR5## wherein R.sub.1 R.sub.2 and R.sub.3 are each independently hydrogen, C.sub.1 -C.sub.3 alkyl, C.sub.1 -C.sub.3 alkoxy, halogen, or hydroxyl groups in an amount effective to control the attachment of barnacles to said surface.
An antifouling coating for an underwater surface which controls the attachment of barnacles to that surface, said coating comprising
- (a) a compound of Formula I:
- ##STR6## wherein R.sub.1, R.sub.2 and R.sub.3 are each independently hydrogen, C.sub.1 -C.sub.3 alkyl, C.sub.1 -C.sub.3 alkoxy, halogen, or hydroxyl groups in an amount effective to control the attachment of barnacles to said surface;
- and
- (b) a film-forming component.
An antifouling cementitious composition comprising a cementitious matrix and a compound of Formula I ##STR7## wherein R.sub.1, R.sub.2 and R.sub.3 are each independently hydrogen, C.sub.1 -C.sub.3 alkyl, C.sub.1 -C.sub.3 alkoxy, halogen, or hydroxyl groups, in an amount effective to control the attachment of barnacles to said surface.
A method of combatting the attachment of barnacles to an underwater surface comprising contacting said organisms with a compound of Formula I:
- ##STR8## wherein R.sub.1, R.sub.2 and R.sub.3 are each independently hydrogen, C.sub.1 -C.sub.3 alkyl, C.sub.1 -C.sub.3 alkoxy, halogen, or hydroxyl groups, in an amount effective to control the attachment of barnacles to said surface.
