Melamine-formaldehyde-sodium bisulfite copolymer

Melamine-formaldehyde-sodium bisulfite copolymer (CAS 64787-97-9), also known commercially as melamine formaldehyde sulfonate sodium salt, is a sulfonated aminoplast polymer used as a dispersant and flocculant.

Where is Melamine-formaldehyde-sodium bisulfite copolymer used?

• Water treatment: coagulation and flocculation of colloidal suspensions in industrial effluent carrying heavy metal ions or organic load
• Process water: sequestrant preventing scale from calcium and magnesium hardness
• Textile and leather: dispersant for dyes and finishing auxiliaries, improving dye uptake uniformity and reducing bath waste
• Pulp and paper: retention aid and drainage improver controlling fiber fines and filler distribution
• Its sulfonated structure provides strong affinity for multivalent ions and suspended particulates.
