Glacial Acrylic Acid (GAA)

Glacial Acrylic Acid Monomer offers significant advantages as an additive in a wide range of copolymer-based finishes, coatings, adhesives, inks, lubricants, saturants, and plastics. Glacial acrylic acid is also used in the production of a wide variety of specialty esters, in drilling fluids and mineral processing chemicals, detergent builders, water treatment chemicals and in superabsorbent materials.

Used in:

  • Textiles, leather, paper finishes
  • Saturants, floor polishes, plastics
  • Coatings & adhesives
  • Viscosity modifiers & thermosetting resins
  • Dispersants & thickeners
  • Superabsorbants & scale inhibitors

Advantages:

  • Flexibility
  • Weatherability
  • Adhesion
  • Internal plasticization
  • Range of hardness
  • Resistance to abrasion and oils or greases
