Description

Morwet Efw CAS NO 105864-15-1 is a high-performance, anionic wetting and dispersing agent belonging to the chemical class of alkyl naphthalene sulfonates. This specialized surfactant is engineered to significantly reduce surface tension and improve the dispersion of solid particles in aqueous and solvent-based systems. It is an essential additive for formulators in the agrochemical, pigment, dye, and construction chemical industries seeking to enhance product stability, uniformity, and processing efficiency.

Application

• Primary dispersant and wetting agent in water-dispersible granules (WG) and suspension concentrates (SC) for agrochemical formulations.
• Grinding aid and stabilizer for organic pigments and carbon black in paints, inks, and coatings.
• Dispersing agent for dyestuffs and fillers in textile and paper processing applications.
• Effective wetting agent in construction chemicals such as cement admixtures and tile adhesives.
• Used in the formulation of detergents and cleaning products for industrial and institutional use.
• Processing aid in the manufacturing of ceramics and other inorganic materials.
