Hydroxypropyl acrylate is a clear, colourless liquid. It is a versatile difunctional acrylate monomer with a characteristic high reactivity. Its high functionality allows end products to be tailored for multiple applications. It can be used for crosslinking with isocyantes or melamines and imparts a range of useful properties to polymers such as hydrophilicity, improved adhesion, weatherability, chemical and scratch resistance.
Synonyms: Viscoat HPA; hydroxypropylacrylat; hydroypropyl acrylate; propyleneglycolacrylate; 2-hydroxyproyl acrylate; 1,2-propanediol, monoacrylate; 1,2(or3)-propanediol, 1-acrylate; acrylic acid, 2-hydroxypropylester
Applications of Hydroxypropyl Acrylate
Hydroxypropyl acrylate forms homopolymers and copolymers. Copolymers of hydroxypropyl acrylate can be prepared with acrylic acid and its salts, amides, esters, methacrylates, acrylonitrile, maleates, vinyl acetate, vinyl chloride, vinylidene chloride, styrene, butadiene, unsaturated polyesters and drying oils. It is also a useful feedstock for chemical syntheses because of its ability to readily undergo addition reactions with a wide range of organic and inorganic compounds.
Hydroxypropyl acrylate is used in a number of end products such as adhesives; UV-reactive oligomers; appliance, coil, can and metal coatings; marine and maintenance finishes; automotive enamels and applications; asphalt modifiers and printing inks.
Storage and Handling
Hydroxypropyl acrylate vapour is any eye irritant. Inhalation causes irritation to the nose and throat and may cause lung injury. Causes burning of the mouth and stomach if ingested. Contact with the liquid causes severe burning to eyes and skin. Proper protective equipment must be worn at all times to avoid injury.
Hydroxypropyl acrylate must contain a stabilizer and should be stored under air rather than inert gases to prevent polymerization. Storage temperature must not exceed 35°C. Provided these storage conditions are properly maintained, the product can be expected to remain stable for a period of one year. However, please note that the trace component of Propylene Glycol Diacrylate increases over time. If this is relevant to your process, the product should be consumed within 6 months.
The product must be stored, handled, distributed and disposed of in strict accordance with national laws and directives, as well as any applicable local regulations. Ensure the container is tightly closed. More detailed information is available in the brochure ‘SAFE HANDLING AND STORAGE OF ACRYLIC ESTERS’, from the European Basic Acrylic Monomers Manufacturers Association (EBAM).
