Abstract
Abstract Organotin compounds that have the structural formula WHEREIN EACH R represents an alkyl group having from four to eight carbon atoms or a phenyl group; one of the X substituents represents an alkyl group having from four to eight carbon atoms, phenyl, or menthyl; the other X substituent represents hydrogen, halogen, nitro, or an alkyl group having from one to four carbon atoms; and Y represents hydrogen, halogen, or nitro, are used to protect surface-coating compositions from deterioration resulting from attack by fungi and other micro-organisms.
