Abstract
A use of tetralin derivatives as biocidal and antifouling agents for preventing and slowing the growth of algae, molds and microorganisms. In particular, the vitamin derivatives are constituted by salts of menadione bisulfite with the heterocyclic bases triazine and piperazine.
Claims7
A method for inhibiting the growth and deposition of a layer of algae, mold or microorganisms on a substrate in need of treatment, comprising the application of an antivegetative, biocidal effective amount of a compound selected from the group consisting of menadione triaminotriazine bisulfite (I) (MTB) and menadione (bis) piperazine bisulfite (II) (MBP) to a substrate.
The method according to claim 3, wherein said compound has a concentration of 0.5% to 10% by weight.
An antifouling composition consisting essentially of a compound selected from the group consisting of menadione triaminotriazine bisulfite (I) (MTB) and menadione (bis) piperazine bisulfite (II) (MBP) in association with a carrier.
An antifouling paint comprising an antivegetative, biocidal effective amount of a compound selected from the group consisting of menadione triaminotriazine bisulfite (I) (MTB) and menadione (bis) piperazine bisulfite (II) (MBP) dispersed in a paint carrier.
