Acrylic Acid
CAS Number: 79-10-7
Acrylic acid is a key unsaturated carboxylic acid monomer used in the synthesis of polyacrylic acid, superabsorbent polymers, acrylic dispersions, and copolymers for coatings and adhesives. Its carboxyl group provides excellent adhesion, water solubility, and crosslinking capability. Available in glacial (neat) and aqueous solution grades.
