Hydroxypropyl methacrylate is a clear, colourless liquid with a strong, sweet odour which is partially soluble in water. It is an ester of methacrylic acid used to make the polymer polyhydroxyethyl methacrylate, which was one of the first materials to be used successfully in flexible contact lenses. It copolymerizes readily with a wide range of monomers, and the added hydroxyl groups provideimproved adhesion to surfaces,hydrophilicity, resistance to corrosion, fogging, and abrasion, incorporate cross-link sites, and reduce odour, colour, and volatility.

Applications of Hydroxypropyl Methacrylate
Hydroxypropyl methacrylate is used in the manufacture of acrylic polymers which in turn are used in a broad range of commercial and consumer applications such as personal care and hygiene products, acrylic paints and resins, adhesives, sealants, binders, printing inks, coatings for automotive, appliance, and metal applications, performance products, reactive systems and as a building block for various chemical syntheses.
Storage and Handling
Contact with hydroxypropyl methacrylate is likely to cause severe irritation of the eyes and could result in permanent injury. It is a moderate skin irritant and may also be harmful if ingested or absorbed through the skin. Inhalation of vapour from the heated product may cause irritation of the nose, throat and lungs. Adequate safety precautions including proper ventilation, engineering controls and the wearing of appropriate personal protective equipment must be observed in order to limit unnecessary exposure.
Hydroxypropyl methacrylate is supplied inhibited to prevent spontaneous polymerization. The product should be stored under air rather than inert gases in order for the inhibitor to remain effective. Avoid excessive heat and sources of ignition, exposure to acids, bases, oxidizing agents, reducing agents, free-radical initiators, organic peroxides, and mild steel. Store in a cool place away from direct sunlight. Provided these storage conditions are properly maintained, the product can be expected to remain stable for a period of one year.
