Butyl Acrylate (BA)

Butyl Acrylate (BA) is an ester of Acrylic acid and is used as a raw material component in the synthesis of polymers. The ester is a monofunctional monomer consisting of an acrylate group with a characteristic high reactivity and a cyclic hydrophobic group. It forms homopolymers and copolymers which can be obtained with acrylic acid and its salts, amides, and esters, as well as methacrylates, acrylonitrile, maleic esters, butadiene, and other monomers.

Butyl Acrylate (BA) is a very useful feedstock for chemical syntheses because it readily undergoes addition reactions with a wide variety of organic and inorganic compounds. It is also used in adhesive and as a polymeric plasticizer for harder resins. The monomer can be used to balance as such key properties as the hardness and softness, tackiness, low-temperature flexibility, strength and durability, and a lot of the others.

Product Type: Acrylate Monomer

In order to prevent polymerization, butyl acrylate 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, a storage stability of one year can be expected. 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. Stainless steel or aluminum should be used for tanks and pipes. Although Butyl acrylate does not corrode carbon steel, there is a risk of contamination if corrosion does occur. Regulations for the storage of flammable liquids must be observed (explosion-proof electrical equipment, vented tanks with flame arresters, etc.). Storage tanks, pumps, and pipes must be earthed. For more detailed information please consult also the brochure “SAFE HANDLING AND STORAGE OF ACRYLIC ESTERS” of EBAM.
