Description

Resin Acids And Rosin Acids, Maleated, Sodium Salts is a chemically modified rosin derivative where the resin acids have undergone a maleation reaction and are subsequently converted to their sodium salts. This modification significantly enhances its water solubility and reactivity, making it a versatile intermediate and functional additive. It is primarily utilized in industries such as paper sizing, adhesive formulation, and as a dispersant or emulsifier in various aqueous systems.

Application

• Paper Sizing Agent: Key component in the production of alkaline paper, improving water resistance and printability.
• Adhesive Formulation: Acts as a tackifier and stabilizer in water-based adhesives and pressure-sensitive adhesives (PSAs).
• Dispersing Agent: Used to stabilize pigments and fillers in aqueous coatings, inks, and ceramic slips.
• Emulsifier: Facilitates the formation and stability of oil-in-water emulsions in industrial and agrochemical applications.
• Soaps and Detergents: Serves as a surfactant and foam stabilizer in cleaning formulations.
• Textile Auxiliary: Used in dyeing and finishing processes to improve fiber processing and dye leveling.
