[Studies on the antimould activity of compound TBZ and its application in paint]

The compound TBZ is a new antimould agent, which contains mainly [2-(4-thiazolyl) benzoimidazole (TBZ)], ethanoic acid and propionic acid. It was shown in laboratory experiment that the compound TBZ had excellent mycostatic effect on all the 10 fungi tested with 70% of the mycostatic zones larger than 6.0 cm. It had obvious inhibitary activity on Alternaria Nees and Aureobasidium Pullulans isolated from mouldy wall. In laboratory condition the surface of fibreboard painted with compound TBZ did not become mouldy in 120 days, while the 20% of that coated with TBZ directly mixed in the paint became mouldy. In practical use, the antimould effect of the wall painted with compound TBZ could maintain more than two years.
