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. Behenyl Methacrylate 1822 (BEMA 1822) is a monofunctional monomer with a long, hydrophobic side chain. This is a mixture of mainly C18, C20, and C22 fatty alcohol methacrylates, which are water-insoluble, low volatility. Behenyl Methacrylate 1822 (BEMA 1822) forms homopolymers and copolymers. Copolymers of Behenyl Methacrylate 1822 F (BEMA 1822 F) can be prepared with (meth)acrylic acid and its salts, amides, and esters, and with methacrylates, acrylonitrile, maleic acid esters, vinyl acetate, vinyl chloride, vinylidene chloride, styrene, butadiene, unsaturated polyesters and drying oils, etc.

Behenyl Methacrylate 1822 (BEMA 1822) 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.

In order to prevent polymerization, Behenyl Methacrylate 1822 F (BEMA 1822 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. If Behenyl Methacrylate 1822 F (BEMA 1822 F) is crystallized the product can be melted safely with heating temperatures up to 60 °C. It should not be stored at this temperature for more than 5 days in order to prevent degradation in quality and premature formation of polymer fractions. In order to reduce thermal stress during the melting process, air convection should be very good. Under such favorable conditions, melting can be achieved within 24 hours. Storage tanks and pipes should be made of stainless steel or aluminum. Storage tanks, pumps, and pipes should be earthed.

Safety

When working with Behenyl Methacrylate 1822 F (BEMA 1822 F), the sanitary rules for organizing technological processes and hygienic requirements for production equipment must be strictly observed. All types of work with Behenyl Methacrylate 1822 F (BEMA 1822 F) must be carried out in rooms equipped with general supply and exhaust ventilation. It is not allowed to carry out work in these rooms using an open fire. Those working with BEMA 1822 must be provided with special clothing and personal protective equipment in accordance with GOST 12.4.034. In the event of a fire, it is necessary to use fire extinguishers OP-5, OVP-100 felt, sand, asbestos cloth. Spilled on solid ground BEMA 1822 should be covered with sand. A Safety Data Sheet has been compiled for Behenyl Methacrylate 1822 F(BEMA 1822 F) that contains up-to-date information on questions relevant to safety.
