acrylate is used primarily for manufacturing homopolymers and
copolymers. N-butyl acrylate can be copolymerized for instance with
acrylic acid and its salts, esters and acrylamide, with methacrylic
acid, methacrylates, acrylonitrile, styrene, maleic acid esters, vinyl
acetate, vinyl chloride, butadiene, unsaturated polyesters etc. N-butyl
acrylate is an important raw material and a starting material for many

N-butyl acrylate is transported in specially equipped railway cars or tanker trucks.
Transport containers are filled to a maximum of 94% of their capacity.
order to prevent spontaneous polymerization, n-butyl acrylate must
always be stored under air, never under inert gases. The air (oxygen
presence is required for a proper functionality of the stabilizer.
Product storage temperature must not exceed 35°C. Under these
conditions, a storage stability of one year can be expected.
It is advisable to minimize the likelihood of n-butyl acrylate overstorage by a strict observance of the “first-in-first-out” storage principle. For storage periods extended over one month, it is advisable to replenish the dissolved oxygen content in the product by suitable aeration.
Stainless steel or aluminium is the recommended material for storage tanks and piping. Even though n-butyl acrylate does not corrode carbon steel, there is a risk of product contamination if corrosion occurs. All metal made equipment (tanks, pumps, piping etc.) must be earthed.
All national laws and directives, as well as local regulations governing storage, handling, distribution and disposal of flammable liquids must be strictly observed. Avoid exposure to high temperatures, sparks, flame, light and frost. Keep separated from oxidizing materials. Keep the container tightly closed.
