TROYSAN PZ50 is a liquid, non-metallic fungicide end-use concentrate that provides proven protection against fungal decay organisms. Based on the well-established biological effectiveness of Propiconazole, TROYSAN PZ50 offers excellent all-around protection against the main types of wood fungi. It can be used as a preservative or in combination with IP BC to prevent blue stain and surface molds. TROYSAN PZ50 is well suited for use in aqueous anti-sapstain formulations combined with IPBC, with the purpose of preventing blue stain and surface molds. It also works well in combination with other wood preservatives suggested for the protection of millwork, including doors, windows, exterior siding, composite board, plywood, and other construction timber, when it is important to prevent the growth of surface molds, blue stain, and wood destroying fungi.
