Behenyl Methacrylate 1822 (BEMA 1822)

Behenyl Methacrylate 1822 (BEMA 1822) is an ester of Methacrylic acid and is used as a raw material component in the synthesis of polymers. The ester is a monofunctional monomer with a long, hydrophobic side chain forms homopolymers and copolymers. This is a mixture of mainly C18, C20, and C22 fatty alcohol methacrylates, which are water-insoluble, low volatility. Its copolymers can be prepared with acrylic acid and its salts, amides, and esters, etc. The monomer readily undergoes addition reactions with a wide variety of organic and inorganic compounds, therefore it is found to be useful in feedstock for chemical syntheses and is employed in paper coatings, textile finishes, and varnishes.

Behenyl Methacrylate 1822 (BEMA 1822) is used in oil additives as a flow/viscosity index improver for highly paraffinic oils and as a pour point depressant. It may also be employed in textile finishes, varnishes, pressure-sensitive adhesives or as co-monomer in paint-resins & plastics.

Features & Benefits: 

  • Hydrophobicity
