Stearyl Methacrylate 1618 (SMA 1618) is an ester of Methacrylic Acid and is used as a raw material component in the synthesis of polymers. The ester is a low viscosity monofunctional monomer with the characteristic high reactivity of acrylates and a long hydrophobic chain. Stearyl Methacrylate 1618 (SMA 1618) is a mixture of mainly C16 alcohol (Cetyl) and C18 alcohol (Stearyl) methacrylates. It forms homopolymers and copolymers which can be prepared with acrylic acid and its salts, amides, and esters, and with methacrylates, acrylonitrile, etc. The monomer is a very useful feedstock for chemical syntheses because it readily undergoes addition reactions with a wide variety of organic and inorganic compounds.
Stearyl Methacrylate 1618 (SMA 1618) is used in oil additives as flow/viscosity index improver for highly paraffinic oils and as pour point depressant. The product may also be employed in concrete and paper coatings, textile finishes, varnishes, pressure-sensitive adhesives. Stearyl Methacrylate 1618 (SMA 1618) may be incorporated as co-monomer in paint resins, hair-care compositions, plastics, and floor care products.
