Dinonylnaphthalenesulfonic acid or DNNSACAS number is 25322-17-2, is a kind of organic compounds. Dinonylnaphthalenesulfonic acid solution is acidic. The sulfonic acid group (-SO3h) in its molecule can provide protons, showing the common properties of acids and can react with bases, metal oxides, etc.
Dinonylnaphthalenesulfonic acid is a cationic surfactant, which can be used as a catalyst for coatings and as a raw material for the production of cooling catalysts (closed and non-closed) for amino baking paint.

DNNSA can be used as a catalyst for coatings, and can also be used as the main raw material for the production of cooling catalysts for amino baking paints. Dinonylnaphthalenesulfonic acid solution is suitable for anodic electrophoretic paint systems because of its hydrophobicity. In anodic electrocoat systems, dinonylnaphthalenesulfonic acid solution transfers and deposits rapidly, and catalyzes the curing reaction of hydroxyl, carboxyl and amino functional groups with alkylated amino resins. Also suitable for solvent and waterborne coating systems to improve corrosion resistance. Due to its high static electricity Therefore, DNNSA is especially suitable for electrostatic spraying. Dinonylnaphthalenesulfonic acid DNNSA is used for coil steel, can paint, automobile paint, general industrial surface and primer. The addition amount is 0.5–2%, dinonylnaphthalenesulfonic acid can reduce the baking temperature and shorten the baking time. Baking time, improve the hardness and chemical resistance of the paint film.
High catalytic efficiency
Dinonylnaphthalenesulfonic acid is suitable for the esterification, etherification, condensation reaction (such as synthesis of plasticizer, resin coating, alternatives to traditional sulfuric acid catalyst can reduce the side effects, reduce product acid); At the same time, it can catalyze the cross-linking reaction of polymer materials and enhance the mechanical properties of the materials.
Excellent rust prevention and corrosion inhibition properties
In the fluid of the lubricating oil, metal processing, Dinonylnaphthalenesulfonic acid adsorption form compact monomolecular film on metal surface, cut off oxygen, water and corrosive medium (e.g., salt fog, organic acids). The anti-rust period for common metals such as steel, copper and aluminum can be extended by 2 to 5 times, and it will not undergo chemical reactions with the metal surface to generate harmful substances.
Low volatility and high heat resistance
Dinonylnaphthalenesulfonic acid solution under normal temperature for viscous liquid, volatile very low boiling point (> 300 ℃), in the high temperature condition (such as engine oil, high temperature paint) in the loss of volatile, can maintain functional stability for a long time.
✅The DNNSA content reaches over 55%, which is higher than the market average of 30% to 50%
✅Cationic type has higher surface activity
✅In stock and with a short delivery cycle
✅The quality is benchmarked against the American brand king1050
