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.
Claims12
An article having an underwater surface to which is bonded a coating which coating controls the attachment of barnacles 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.
A method of combatting the attachment of barnacles to an article having an underwater surface comprising;
- (a) coating the underwater surface with a composition containing 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 surface;
- and then
- (b) contacting said barnacles with a compound of Formula I.
