Stearyl Methacrylate 1618 F (SMA 1618 F)

Stearyl Methacrylate 1618 F (SMA 1618 F) is an ester of Methacrylic Acid and is used as a raw material component in the synthesis of polymers. Stearyl Methacrylate 1618 F (SMA 1618 F) is a low viscosity functional monomer with the characteristic high reactivity of acrylates and a long hydrophobic chain. Stearyl Methacrylate 1618 F (SMA 1618 F) is a mixture of mainly C16 alcohol (Cetyl) and C18 alcohol (Stearyl) methacrylates. Stearyl Methacrylate 1618 F (SMA 1618 F) forms homopolymers and copolymers which can be prepared with acrylic acid and its salts, amides, and esters, and with methacrylates, acrylonitrile, etc.

Stearyl Methacrylate 1618 F (SMA 1618F ) is a very useful feedstock for chemical syntheses because it readily undergoes addition reactions with a wide variety of organic and inorganic compounds.

Product type: Methacrylate Monomer

Features & Benefits:

Characteristics:

  • Stearyl Methacrylate 1618 F (SMA 1618F ) is used in oil additives as a flow/viscosity index improver for highly paraffinic oils and as pour point depressant. Stearyl Methacrylate 1618 F (SMA 1618 F) may also be employed in concrete and paper coatings, textile finishes, varnishes, pressure-sensitive adhesives, anti-slip coatings, emulsifiers. Stearyl Methacrylate 1618 F (SMA 1618 F) may be incorporated as co-monomer in paint resins, hair-care compositions, plastics, and floor care products.

It is applied in the production of:

  • In oil additives as flow improver
  • In-floor waxes
  • Automotive coatings
  • Textile and metal coatings
  • Varnishes
  • Adhesives, low temperature caulks, and sealants.
  • As co-monomer in paint resins, elastomers, and plastics.
  • Stabilizer in non-aqueous dispersions and inks.
  • Electronics and encapsulated products

In order to prevent polymerization, Stearyl Methacrylate 1618 F (SMA 1618 F) must always be stored under air, and never under inert gases. The presence of oxygen is required for the stabilizer to function effectively. It has to contain a stabilizer and the storage temperature must not exceed 35 °C. Under these conditions, the storage stability of one year can be expected upon delivery. In order to minimize the likelihood of over storage, the storage procedure should strictly follow the “first-in-first-out” principle. For extended storage periods over 4 weeks, it is advisable to replenish the dissolved oxygen content. If Stearyl Methacrylate 1618 F (SMA 1618 F) accidentally is crystallized the product should never be partially molten and taken because of the possible separation from the stabilizer. Ensure that there is no crystallized product in the container before use. Obtain information from supplier/manufacturer before dissolving totally or partially crystallized product. The ambient temperature of the container may not exceed the stated temperature limit when melting the product or keeping it at a moderate temperature. The preferred construction material for tanks and pipes is stainless steel. Carbon steel is also acceptable, although the formation of rust may be a problem with product quality (color). Iron(III)-ions have been shown to be a weak polymerization initiator. If carbon steel is to be used, special procedures should be used to prepare the tank for use. Storage tanks, pumps, and pipes should be earthed.
