HVAC systems having interior surfaces exposed to moist air are protected against fungal growth by coating the interior surfaces with an adherent flexible polymer film which includes a fungicidal composition in an amount effective to provide a zone of inhibition against multiple fungal species of at least 1 mm, and which employs active fungicidal ingredients which are substantially non-volatile and non-soluble in water. Suitably the film is formed by application of a latex coating formulation, free of arsenic, mercury, lead, tin, chlorine or bromine, the formulation comprising an emulsion of a flexible polymer having suspended therein a mixture of fungicides, the fungicide mixture including a barium metaborate fungicide and a second fungicide selected from the group consisting of iodo alkynyl alkyl carbamates, diidomethyl-p-tolylsulfone, 2-4-thiazolyl-benzimidazole, 2-n-octyl-4-isothiazolin-3-one, zinc dimethyldithiocarbamate, zinc 2-mercaptobenzothiazole, potassium n-hydroxymethyl-n-methyldithiocarbamate, sodium 2-mercaptobenzothiazole, 5-hydroxymethoxymethyl-1-aza-3,7-dioxa-bicyclooctane, 2,3,5,6-tetrachloro-4-pyridine, zinc 2-pyridinethiol-1-oxide and N-trichloromethylthiophthalimide.
暖通空调系统的内表面暴露在
潮湿的空气中,为防止真菌生长,可在这些内表面涂上一层附着性柔性聚合物薄膜,该薄膜含有杀真菌成分,其有效用量可提供至少 1 毫米的多种真菌抑制区,并且采用了基本上不挥发且不溶于
水的活性杀真菌成分。合适的薄膜是通过使用不含
