Glacial acrylic acid (CAS No. 79-10-7), also known as prop-2-enoic acid, is one of the main raw ingredients that gives rise to many acrylic polymers. Acrylic acid reacts as both a vinyl compound and a carboxylic acid with various organic and inorganic compounds, making it useful as a feedstock for producing many low–molecular weight compounds. When acrylic acid reacts with alcohols, the resulting solution forms esters known as acrylates. Acrylic acid and its esters are often used as components for polymers such as coating resins, thickeners, dispersing agents, flocculants, protective colloids, wetting agents, and textile finishes. This means glacial acrylic acid is a base raw material for industries such as adhesives, coatings, inks, plastics, elastomers, water treatment, and personal care.

Glacial acrylic acid must be handled with care, as it is highly susceptible to dimerization. If it is frozen, extreme precaution should be taken when thawing the monomer to prevent any runaway polymerization and potential explosions. This product has a glossy consistency and is highly soluble in water.
