Densil® DN Antimicrobial is a broad spectrum fungicide, bactericide and algaecide based on the active ingredient N-butyl-1,2-benzisothiazolin-3-one (BBIT). Densil DN Antimicrobial can be used to prevent microbial degradation of various building construction materials in different application areas, to offer dry film and wet state preservation. Many building construction materials can support the growth of a wide range of microorganisms, both in the wet state and on the dry film. Microbial colonization and growth in such material can result in aesthetic damage & loss of functional properties of the products.

The concentration required to adequately preserve a product depends on several factors. These include the susceptibility of the system to microbiological degradation, the extent to which microorganisms can gain access, the species involved, pH, temperature, and length of time for which protection is required. Since the effective concentration can be dependent on several factors we recommend that compatibility/stability trials and microbiological challenge testing should be carried out before use. Densil DN Antimicrobial is found to be an effective wet state preservative at concentrations of 0.01% to 0.05% and effective dry film preservative at concentrations of 0.075% to 0.115%. Please refer to TDS for example end-use applications and suggested addition.
