ABSTRACT:
Compositions for protecting materials from growth of pestiferous organisms, and particularly for protecting marine surfaces from fouling organisms, are formed from precursors having the formula ##STR1## where m is from 1 to about 10, where each X is independently selected from the group consisting of alkyl and alkoxyalkyl radicals containing less than about 6 carbon atoms and Y, where Y has the formula ##STR2## where R.sub.1 R.sub.2 and R.sub.3 are independently selected from the group consisting of alkyl, cycloalkyl, and aryl radicals, where R.sub.1, R.sub.2 and R.sub.3 contain in combination up to about 18 carbon atoms. The ratio of the tin atoms to silicon atoms in the precursors is at least about 1:50.
The precursors can be directly used as an additive for coatings. The precursors can also be used by subjecting them to hydrolysis and polycondensation to form an organotin substituted polysiloxane for use as an additive and a binder for coatings.
