Abstract
A composition for preservation of wood and wood-based materials, comprising 0.001%-5% by weight of 1-[[2-(2,4-dichlorophenyl)-1,3-dioxolan-2-yl]methyl]-1H-1,2,4-triazole, 0.001%-3% by weight, of at least one of cyano-(4-fluoro-3-phenoxyphenyl)-methyl-3-(2,2-dichloroethenyl)-2,2-dimeth ylcyclopropylcarboxylate, ((pentafluorophenyl)-methyl)-1R,3R-3-(2,2-dichloroethenyl)-2,2-dimethylcyc lopropylcarboxylate, methylbisthiocyanate, and N,N-dimethyl-N'-phenyl-N'-(fluorodichloromethyltolyl-N'-(dichlorofluoromet hylthio)sulfamide and suspending agent comprising at least one of a diluent, an emulsifier, and a wetting agent, is provided together with a process for preparing such compositions.
Claims23
A composition for preservation of wood and wood-based materials comprising:
- (a) from about 0.001% to 5%, based on the total weight of all components, of a compound 1-[[2-(2,4-dichlorophenyl)-1,3-dioxolan-2-yl]methyl]-1H-1,2,4-triazole,
- (b) from about 0.001% to 3%, based on the total weight of all components, of at least one compound selected from the group consisting of

- (ii) ((pentafluorophenl)methyl)-1R,3R-3-(2,2-dichloroethenyl)-2,2-dimethylcyclo propylcarboxylate, and
- (c) a suspending agent selected from the group consisting of a diluent, an emulsifier, a wetting agent and mixtures thereof.
A process for preparation of a composition for the preservation of wood and wood based materials comprising the step of mixing
- (a) from about 0.001% to 5%, based on the total weight of all components, of a compound 1-[[2-(2,4-dichlorophenl)-1,3-dioxolan-2-yl]methyl]-1H-1,2,4-triazole,
- (b) from about 0.001% to 3%, based on the total weight of all components, of at least one compound selected from the group consisting of
- (i) cyano-(4-fluoro-3-phenoxyphenyl)-methyl-3-(2,2-dichloroethenyl)-2,2-dimeth ylcyclopropylcarboxylate, and
- (ii) ((pentafluorophenyl)methyl)-1R,3R-3-(2,2-dichloroethenyl)-2,2-dimethylcycl opropylcarboxylate, and
- (c) a suspending agent selected from the group consisting of a diluent, an emulsifier, a wetting agent and mixtures thereof.
