Q1: What is the primary mode of action of BASF Protectol 140 Fungicide?
A: BASF Protectol 140 Fungicide functions as a broad-spectrum preventive and curative fungicide, primarily inhibiting fungal cell membrane synthesis through interference with ergosterol biosynthesis. Its active ingredient belongs to the triazole chemical class, providing systemic activity and residual protection in treated substrates.
Q2: In which types of industrial formulations is Protectol 140 commonly used?
A: Protectol 140 is widely incorporated into water-based industrial coatings, adhesives, sealants, construction materials (e.g., cementitious and gypsum-based products), and polymer dispersions where long-term resistance against mold, mildew, and saprophytic fungi is required under humid or damp conditions.
Q3: How stable is Protectol 140 in alkaline environments such as cementitious systems?
A: Protectol 140 demonstrates good compatibility and stability across a broad pH range, including moderately alkaline conditions typical of cement- and lime-based formulations. It maintains fungicidal efficacy without significant degradation during early curing stages, though prolonged exposure to highly alkaline media (>pH 12.5) may gradually reduce performance over time.
Q4: Is Protectol 140 suitable for use in interior applications requiring low-VOC compliance?
A: Yes — Protectol 140 is formulated as a low-volatility, non-aqueous liquid concentrate with negligible vapor pressure. When dosed at recommended levels, it contributes minimally to overall VOC content and supports compliance with major low-VOC regulatory frameworks for interior building products.
