核心特性 :
  • Low curing shrinkage and low volatility

  • Excellent flexibility and toughness

  • Higher Tg compared to stearyl acrylate for better heat resistance

  • Outstanding weather resistance and water resistance

  • Long C18 hydrophobic chain for effective hydrophobicity

  • Good compatibility with oil-based and non-polar systems


应用 :

SINOMER® SMA is a versatile hydrophobic monomer used in a wide range of polymer synthesis applications:

  • Coatings & Inks – Used as a hydrophobic comonomer in coatings, printing inks, and release coatings, where it improves water resistance, flexibility, and weatherability.

  • Textile & Leather Auxiliaries – Applied in textile dyeing and finishing auxiliaries, leather auxiliaries, and waterproof/oil-proofing agents, providing durable hydrophobic protection.

  • Lubricating Oil Additives – Used in the synthesis of lubricating oil additives and flow improvers, where the long alkyl chain effectively modifies viscosity-temperature behavior.

  • Crude Oil Viscosity Reducers – Functions as a monomer for polymeric flow improvers and pour point depressants in crude oil transportation.

  • Adhesives & Sealants – Improves flexibility, moisture resistance, and adhesion in various adhesive formulations.
