Abstract

Wallboard and facing paper that provides increased mold resistance at lower biocide loadings. The biocide is: (a) an n-alkyl isothiazolinone such as octylisothiazolinone (OIT), a monohalo and dihalo substituted n-alkylisothiazolinone such as chloromethylisothiazolinone (CMIT) or dichlorooctylisothiazolinone (DCOIT), 3-iodo-2-propynyl-butylcarbamate (IPBC), chlorothalonil, methylene-bis-thiocyanate, or mixtures of two or more thereof; or (b) carbendazim and a second biocide selected from 3-iodo-2-propynyl-butylcarbamate (IPBC), diiodomethyltolylsulfone (DIMTS), sodium pyrithione, octylisothiazolinone (OIT), dichlorooctylisothiazolinone (DCOIT), and chlorothalonil.
