General information:

Sinomer® SA is a monomer with low shrinkage and volatility, flexibility, excellent weather resistance and water resistance. It can be widely used in inks, release coatings, coatings and textile coatings.

Standard

 Applications:

• Amphiphilic Polymer Hydrophobic Monomer:
  Used in the synthesis of amphiphilic polymers, polymeric emulsifiers, polymeric stabilizers, and self-emulsifying leather waterproofing agents. It can copolymerize with hydrophilic monomers (e.g., acrylic acid, maleic acid, acrylamide) to generate amphiphilic polymers.
• Hydrophobic Monomer for Polymer Waterproofing Materials:
  Applied in the synthesis of fabric “three-proof” (waterproof, oil-proof, stain-resistant) finishing agents and fluorine-free waterproofing agents.
• Hydrophobic Monomer for Hydrophobically Associating Thickeners:
  A small amount of stearyl acrylate is added to hydrophilic monomers (e.g., acrylamide) during copolymerization. In aqueous polymer solutions, the stearyl side chains associate reversibly, forming hydrophobic crosslinking points.
• Monomer for Crude Oil Pour Point Depressants:
  Acts as a primary monomer to polymerize and produce polymeric pour point depressants for crude oil.
• Functional Monomer for Other Polymer Syntheses:
  Suitable for diverse polymer applications requiring hydrophobic modification.
• High Glass Transition Temperature (Tg) in Homopolymers:
  While stearyl acrylate homopolymers exhibit a high Tg, practical applications often involve low-molecular-weight polymers with reduced melting points.

Package:10kg,100kg,150kgs/drum.
