Abstract

A microbicidal composition containing: (a) at least one non-halogenated 2-alkyl-4-isothiazolin-3-one selected from substituted and unsubstituted 2-(C 1 -C 4 )alkyl-4-isothiazolin-3-ones; and (b) at least one of 2,2′-dithiobis(N-methylbenzamide) and 2-methylbenzisothiazolone.

Claims (10)

1. A microbicidal composition comprising:

(a) at least one non-halogenated 2-alkyl-4-isothiazolin-3-one selected from unsubstituted 2-(C 1 -C 4 )alkyl-4-isothiazolin-3-ones; and

(b) 2,2′-dithiobis(N-methylbenzamide)

wherein a weight ratio of said at least one non-halogenated 2-alkyl-4-isothiazolin-3-one to 2,2′-dithiobis(N-methylbenzamide) is from 375:1 to 1:20.

2. The composition of claim 1 in which said at least one non-halogenated 2-alkyl-4-isothiazolin-3-one is 2-methyl-4-isothiazolin-3-one.

3. The composition of claim 2 in which said weight ratio is from 100:1 to 1:20.

4. A paint composition comprising from 50 ppm to 500 ppm of a synergistic microbicide composition; said synergistic microbicide composition comprising:

(a) 2-methyl-4-isothiazolin-3-one; and

(b) 2,2′-dithiobis(N-methylbenzamide);

wherein a weight ratio of 2-methyl-4-isothiazolin-3-one to 2,2′-dithiobis(N-methylbenzamide) is from 375:1 to 1:6.
