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砷、汞、铅、锡、氯或溴的乳胶涂层配方形成的,该配方包括柔性聚合物乳液,其中悬浮有杀真菌剂混合物,杀真菌剂混合物包括偏硼酸钡杀真菌剂和选自碘炔基烷基氨基甲酸酯组的第二种杀真菌剂、2-巯基苯并噻唑锌盐、2-巯基苯并噻唑锌盐、2-羟甲基-N-甲基二硫代氨基甲酸钾、2-巯基苯并噻唑锌盐、2-巯基苯并噻唑锌盐、2-巯基苯并噻唑锌盐、2-巯基苯并噻唑锌盐、2-巯基苯并噻唑锌盐、2-巯基苯并噻唑锌盐、2-巯基苯并噻唑锌盐、2-巯基苯并噻唑锌盐、2-巯基苯并噻唑钠、5-羟基甲氧基甲基-1-氮杂-3,7-二氧杂环辛烷、2,3,5,6-四氯-4-吡啶、2-吡啶硫醇-1-氧化锌和 N-三氯甲基硫代酞酰亚胺。
