Hydroxypropyl methacrylate

HPMA is a clear, colorless liquid with a pungent, sweet odor. The product contains low levels of a polymerization inhibitor along with small amounts of methacrylic acid, and propylene oxide. HPMA is used in the manufacture of acrylic polymers for adhesives, inks, and coatings for automotive, appliance and metal applications. The added hydroxyl groups improve adhesion to surfaces, incorporate cross-link sites, and impart corrosion, fogging, and abrasion resistance.
