2-Hydroxypropyl Acrylate (2-HPA)
2-Hydroxypropyl Acrylate (2-HPA) is an ester of Acrylic acid and is used as a raw material component in the synthesis of polymers. 2-Hydroxypropyl Acrylate (2-HPA) is a monofunctional acrylate monomer with a characteristic high reactivity of methacrylates and a branched hydrophobic moiety. 2-Hydroxypropyl Acrylate (2-HPA) forms homopolymers and copolymers. Copolymers of Hydroxypropyl Acrylate (2-HPA) can be prepared with (meth)acrylic acid and its salts, amides, and esters, and with (meth)acrylates, acrylonitrile, maleic acid esters, vinyl acetate, vinyl chloride, vinylidene chloride, styrene, butadiene, unsaturated polyesters, and drying oils, etc.
2-Hydroxypropyl Acrylate (2-HPA) is also a very useful feedstock for chemical syntheses because it readily undergoes addition reactions with a wide variety of organic and inorganic compounds.

In order to prevent polymerization, Hydroxypropyl Acrylate (HPA) must always be stored under air, and never under inert gases. The presence of oxygen is required for the stabilizer to function effectively. It has to contain a stabilizer and the storage temperature must not exceed 35 °C. Under these conditions, the storage stability of one year can be expected upon delivery. In order to minimize the likelihood of over storage, the storage procedure should strictly follow the “first-in-first-out” principle. For extended storage periods over 4 weeks, it is advisable to replenish the dissolved oxygen content. Over time the content of Propylene Glycol Diacrylate slowly increases. If this trace component is relevant to your process, the material should be consumed within the latest 6 months after receipt of the material. The preferred construction material for tanks and pipes is stainless steel. Carbon steel is also acceptable, although the formation of rust may be a problem with product quality (color). Iron(III)-ions have been shown to be a weak polymerization initiator. If carbon steel is to be used, special procedures should be used to prepare the tank for use. Storage tanks, pumps and pipes should be earthed.
