Abstract
Abstract Novel compositions of matter and processes for utilizing such compositions in preserving wood are described. More particularly, the novel compositions comprise (A) at least one metal salt of an organic carboxylic acid containing at least about 6 carbon atoms wherein the metal is selected from the group consisting of transition metals, zinc, mercury, antimony and lead, (B) at least one isothiazolone compound represented by the structural formula ##STR1## wherein R 1 is an alkyl, alkenyl or alkynyl group of 1 to about 18 carbon atoms; a cycloalkyl group having a 3 to 6 carbon atom ring and up to about 12 carbon atoms; an aralkyl or aryl group of up to about 10 carbon atoms; R 2 is hydrogen, halogen or a lower alkyl group; and R 3 is hydrogen, halogen or a lower alkyl group, and p0 (C) at least one solvent/diluent. The solvent/diluent may be water or one or more hydrocarbon solvents. The novel compositions of the invention are useful in preserving wood, and when so used, the compositions also may include flame retardants, water repellents, odorants, insecticides, etc.
