Naphthalene sulfonates are widely used in building chemistry as a superplasticizer for their dispersing and wetting abilities. They come in different forms (calcium and sodium salt) and various levels of sodium sulfate %. Naphthalene sulfonate creates concrete that is more workable and fluid by using less water and more slump. Naphthalene sulfonate is a type of surfactant that is derived from naphthalene, a hydrocarbon compound found in coal tar and is used as a wetting agent in drywall, helping to reduce the surface tension of water, allowing it to penetrate and moisten the gypsum particles more effectively. This improves the workability and adhesion of the drywall, as well as the drying time and strength.
