2 ethylhexyl acrylate is an acrylic ester used for polymer manufacturing and as an important starting material for many chemical syntheses. It is a colourless liquid with a strong but pleasant odour. Though stable, it polymerizes readily and is therefore usually supplied inhibited.
Synonyms: Acrylic acid octyl ester; acrylic acid octyl ester monomer; acrylic acid 2-ethylhexyl ester monomer; acrylic acid 2-ethylhexyl ester; 2-ethylhexyl 2-propenoate; 2-ethylhexyl acrylate; 2-ethylhexyl acrylate monomer; octyl acrylate
Applications of 2 Ethylhexyl Acrylate
2 ethylhexyl acrylate is predominantly used in acrylic pressure-sensitive adhesives, sealants for exterior use and various coatings. Its presence gives improved water and sunlight resistance to the final product. 2 ethylhexyl acrylate is used in the manufacturing of homopolymers and copolymers. 2 ethylhexyl 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.
Storage and Handling
2 ethylhexyl acrylate must be stored under air rather than inert gases in order to prevent spontaneous polymerization. The presence of oxygen is essential for a proper functionality of the stabilizer. Do not store at temperatures above 35°C. Provided these storage conditions are properly maintained, the product can be expected to remain stable for a period of one year.
It is recommended that you operate a strict “first-in-first-out” storage principle in order to minimise over-storage of 2 ethylhexyl acrylate. Replenishing the dissolved oxygen content by means of suitable aeration is advised if storage periods exceed one month.
Though 2 ethylhexyl acrylate does not corrode carbon steel, there is a risk of product contamination if any corrosion occurs, therefore storage tanks and piping of stainless steel or aluminium are recommended. All metallic tanks, pumps, piping and other equipment must be earthed.
The product must be stored, handled, distributed and disposed of in strict accordance with national laws and directives, as well as any applicable local regulations. Do not expose to high temperatures, sparks, flame, light or frost. Must be kept separate from oxidizing materials. Ensure the container is tightly closed.
