An antifouling paint composition stabilized against viscosity increase and gelation during storage which comprises triorganotin-containing polymer and cuprous oxide as combined active ingredients, a stabilizing amount of a hindered phenol, and a solvent therefor.
In an antifouling paint composition comprising triorganotin-containing polymer and cuprous oxide as combined active ingredients, the improvement comprising an amount of hindered phenol sufficient to stabilize said composition against viscosity increase and gelation during storage.
A method of stabilizing an antifouling paint composition, comprising, as combined active ingredients:
- (a) triorganotin-containing polymer and
- (b) cuprous oxide,
- against viscosity increase and gelatin during storage, which comprises incorporating in the composision a stabilizing amount of a hindered phenol selected from the group consisting of 2,6-di-tert-butylphenol, 2,5-di-tert-butylhydroquinone, 2,2'-methylenebis(4-methyl-6-tert-butylphenol) and 2,2'-methylenebis(4-ethyl-6-tert-butylphenol).
