Resin acids and rosin acids, fumarated, compounds with triethanolamine is a rosin-based modified surfactant and resin additive. It is mainly used as an emulsifier, dispersing agent, wetting agent, and adhesion promoter in coatings, inks, adhesives, paper chemicals, rubber processing, and industrial formulations. It improves compatibility, emulsification stability, and surface properties of formulated products.
