Sodium methallyl sulfonate Usage
-
The Third Monomer for Acrylic Fiber (Core Application): A functional third monomer used in the production of acrylic fibers. It significantly improves the dyeing performance of the fiber, giving it excellent properties such as fast dyeing, high dye absorption, good leveling, bright colors, and resistance to sunlight.
-
Polycarboxylate Superplasticizer for Concrete (Advanced Building Admixtures): In the building materials field, it is widely used as an important comonomer in the manufacture of polycarboxylate-based high-performance water-reducing agents. It imparts strong negative charge repulsion and steric hindrance effects to cement particles, thereby significantly improving the fluidity and slump retention of concrete and reducing water loss.
-
Water Treatment Antiscalant & Flocculant: Copolymerized with monomers such as acrylic acid and acrylamide, it is used to produce polymeric water treatment scale inhibitors and dispersants and polymeric flocculants, exhibiting excellent efficacy in inhibiting calcium carbonate and calcium phosphate scale.
-
Specialty Coatings & Textile Helpers: Used as a reactive emulsifier in the coatings industry; used as an antistatic agent, leveling agent, and sizing agent in textile printing and dyeing; and as a raw material for the production of chemicals in the paper industry.

Sodium methallyl sulfonate Storage
Must be stored in a cool, dry, and well-ventilated chemical raw material warehouse. Keep containers hermetically sealed and completely protected from moisture, rain, and water ingress. Keep away from open flames, ignition vectors, and powerful oxidizers. Avoid joint storage with strong mineral acids.
