Description

Calcium Di(Naphthalene-1-Sulphonate) is an organosulfonate salt widely utilized as a high-performance dispersant and surfactant in industrial formulations. Its primary value lies in its ability to effectively stabilize particles and reduce surface tension in complex aqueous and non-aqueous systems. This compound is essential for manufacturers in sectors such as construction, agrochemicals, and specialty chemicals who require reliable additive performance to ensure product consistency and efficacy.

Application

• Primary dispersant and grinding aid in the production of construction materials like concrete admixtures and cement additives.
• Key surfactant component in agrochemical formulations, including pesticides, herbicides, and fungicides, to enhance stability and spreading.
• Stabilizing agent and emulsifier in the manufacture of dyes and pigments for textiles, inks, and coatings.
• Additive in oilfield chemicals for drilling muds and fluid loss control applications.
• Processing aid in ceramic and clay production to improve slurry rheology and particle distribution.
• Intermediate in the synthesis of other specialty sulfonated compounds and surfactants.
