2-Hydroxypropyl methacrylate (HPMA)
Hydroxypropyl methacrylate (HPMA). It is a clear, colourless liquid with a characteristic odour. It is an ester of methacrylic acid. It is relatively non-volatile, non-toxic and non-yellowing.
HPMA copolymerizes readily with a wide variety of monomers, and the added hydroxyl groups improve adhesion to surfaces, incorporate cross-linking sites, and impart corrosion, fogging, and abrasion resistance, as well as contribute to low odour, colour, and volatility.
HPMA is used in the manufacture of acrylic polymers for adhesives, printing inks, coatings and metal applications. HPMA is also used as reactive diluent and alternative to styrene in unsatured polyester (UPR).
HPMA compared to HEMA is more suitable when a better water resistance is required, together with a better shrinkage resistance.
Under proper storage conditions, the shelf life is 12 months.
