VERZONE DFA-1 is a highly concentrated, water-soluble anti-rust additive for aluminum and its alloys, effectively preventing corrosion in alkaline and acidic liquids, especially in water-soluble cutting oils and detergents. This pale yellow, clear liquid (pH 8.7 at 1% solution, viscosity 1.05 at 20°C) forms an ultrathin, protective chemical film on metal surfaces without adverse effects. Its organic composition ensures long-term stability, preventing viscosity changes or crystallization. Requiring minimal addition (e.g., 0.15% for remarkable rust prevention in alkaline liquids), it demonstrates splendid and continuous rust prevention, as validated by multi-cycle testing, making it ideal for water-soluble cutting oil and detergent applications.
