👉 A diquat is a chemical compound that has been used historically in the production of paints and varnishes, particularly for use in the manufacturing of lacquer. It is made by combining a polymer with a liquid solvent or emulsion, such as ethanol or methanol, to form a gel-like substance known as a diquat. This type of compound is commonly used in the manufacture of lacquers, varnishes, and other similar products.
