Description

2-Methylphenol, Formaldehyde, Phenol Polymer, Sulfonated, Sodium Salt is a synthetic, water-soluble anionic polymer derived from phenolic resins. This specialized chemical is engineered to function as a highly effective dispersant, plasticizer, and viscosity modifier in aqueous systems. It is a critical performance additive for industries requiring precise control over rheology and particle suspension, such as construction, ceramics, and textile processing.

Application

• As a superplasticizer and water-reducing agent in high-performance concrete and cementitious formulations.
• As a dispersing agent for ceramic glazes, pigments, and inorganic fillers to prevent agglomeration.
• As a tanning auxiliary and dye dispersant in leather processing and textile industries.
• As a viscosity modifier and stabilizer in water-based drilling muds and other oilfield chemicals.
• As a plasticizer and grinding aid in the production of gypsum board and other building materials.
• In the formulation of clay and coal slurry dispersants for mining and mineral processing operations.
