The DA-50 dispersing and anti-settling multifunctional additive produced by Shanghai Paint Research Institute and Shanghai Changfeng Chemical Plant is composed of polycarboxylic acid organic ammonium neutral salt. This product has the advantages of dispersion, anti-settling, inhibition of floating color, blooming, and change.

Rheological properties of the coating, corrosion inhibition on iron materials, etc. It is suitable for inorganic pigments such as iron oxide pigments, chrome yellow pigments, titanium dioxide, etc., and can be used for various resins other than moisture-curing polyurethane and water-based paints. The dosage of the system is 0.2%~0.5% of the total solids.

Derivatives of organic phosphonate and phosphoric acid have been used in coatings for many years. Low-molecular-weight alkyl phosphate can be used as a catalyst for accelerated curing of melamine and aldehyde crosslinking agents. Phosphoric acid itself can be added to some coatings to improve adhesion. Phosphorus pentoxide reacts with hydroxyl compounds to prepare surfactants.

Organic phosphonates can be used to treat metal surfaces before painting. The Lubrizol wax Corp. “Developed a series of such products under the trade name Lubrizol. This type of additive is a highly polar resin material, which can replace 0.5% to 5% of the paint without changing the main formula. Lubrizol 2061 is a composite Alkyl phosphate and aryl phosphate mixture free acid isobutanol solution, suitable for steel, galvanized sheet, aluminum and alloy substrates, for oily ethylene/acrylic, epoxy, alkyd/polyester and polyurethane coatings Medium; Lubrizol2062 is a phosphate alkyl/aryl ester free acid coordination compound, suitable for steel, galvanized sheet, aluminum and copper substrates, used in oily ethylene/acrylic, epoxy, alkyd/polyester and polyurethane coatings ; Lubrizol 2063 is a compound carboxylic acid phosphate free acid butyl cellosolve solution, suitable for steel, galvanized sheet, aluminum and copper substrates, for oily ethylene/acrylic, epoxy, alkyd/polyester and polyurethane coatings middle.
