Sodium methyl naphthalenesulfonate-formaldehyde copolymer

Sodium methyl naphthalenesulfonate-formaldehyde copolymer (CAS 9008-64-4), also known as methyl naphthalene sulfonic acid-formaldehyde condensate sodium salt, is a synthetic anionic dispersant.

Where is Sodium methyl naphthalenesulfonate-formaldehyde copolymer used?

• Construction: water-reducing plasticizer in concrete and cement, lowering water-to-cement ratios while maintaining slump
• Agriculture: dispersant and wetting agent in wettable powder and suspension concentrate pesticide products
• Textile and leather: improves dye dispersion and leveling for uniform penetration
• Paper manufacturing: controls fiber dispersion during high-speed processing and improves coating rheology
• It reduces water demand in industrial processing.

Commercial specifications

• Solid content typically 85–95% for powder grades
• Variations in sulfonation degree and molecular weight available
