Abstract:

Although antifouling coatings are complex systems which contain four or five coordinate organotin compounds that are monomeric or polymeric, a simple diffusion model adequately explains the time release of organotin toxicant from the coatings. This result suggests that the mechanisms of release is dependent primarily on matrix properties rather than the chemistry of individual compounds. Whereas, our understanding of the leaching of organotin compounds of the type R3SnY where R is phenyl or butyl in aqueous solutions is still incomplete, we believe the Y group to be liable and R3SnOH or R3SnCl to be the species formed in seawater.
