ABSTRACT OF THE DISCLOSURE <<Improving algae or micro-organism anti-fouling of materials>> A method of reducing the susceptibility of materials to fouling by algae or microorganisms comprises treating the material with an anti-fouling agent selected from certain tin compounds. The compounds which may be used are selected from inorganic divalent tin salts, monoorgano tin compounds of formula R Sn X3 and diorgano tin compounds of formula R2SnX2, in which R represents a hydrocarbon radical and X represents inorganic radicals or an organic radical other than hydrocarbon. The compounds are particularly suitable for treating soft PVC materials by mixing in with the moulding compositions. They are generally of lower toxicity than hitherto used anti-fouling agents, and give good results in the prevention of algae deposit on, for example, swimming pool sheeting.
