Description

1-Naphthalenesulfonic Acid, Polymer With Formaldehyde, Calcium Salt is a high-performance, water-soluble polymeric dispersant and superplasticizer. This compound is engineered to provide superior concrete workability, water reduction, and dispersion properties in demanding construction and industrial applications. It is a critical raw material for manufacturers of advanced concrete admixtures, gypsum board, and ceramic processing aids, where consistent quality and reliable performance are paramount.

Application

• Concrete Superplasticizer: Primary component in high-range water-reducing admixtures (HRWR) for high-strength and self-compacting concrete.
• Gypsum Board Dispersant: Enhances slurry fluidity and improves the formation and strength of wallboard and plaster.
• Ceramic Processing Aid: Acts as a grinding aid and deflocculant to improve the rheology of ceramic slips and slurries.
• Pigment & Dye Dispersant: Used in the production of concentrated pigment pastes and dye formulations to ensure stability and color development.
• Oilfield & Drilling Fluids: Functions as a fluid loss control additive and dispersant in cementing and drilling mud applications.
• Textile & Leather Auxiliary: Employed as a leveling agent and dispersant in dyeing and tanning processes.
• Agricultural Formulations: Used as a dispersing agent in wettable powders and suspension concentrates for pesticides.
• Industrial Cleaning: Component in scale inhibition and dispersant formulations for cooling water and boiler systems.
