Scope

Scope: This document specifies the requirements, test methods, inspection rules, marking, packaging, transportation, storage, and safety of industrial methyl acrylate hydroxyethyl ester, 2-methyl acrylate monoester of 1,2-propanediol, and 2-acrylate monoester of 1,2-propanediol. This document applies to methyl acrylate hydroxyethyl ester produced by ring-opening esterification of methyl acrylate and ethylene oxide, 2-methyl acrylate monoester of 1,2-propanediol produced by ring-opening esterification of methyl acrylate and propylene oxide, and 2-acrylate monoester of 1,2-propanediol produced by ring-opening esterification of acrylic acid and propylene oxide. Products are mainly used in coatings, ink resins, adhesives, and water-reducing agents.
