1. Primarily used for modifying resins and coatings. Copolymerizing with other acrylic monomers, it produces acrylic resins containing reactive hydroxyl groups in their side chains. These can undergo esterification and cross-linking reactions to synthesize insoluble resins and improve adhesion, making them suitable for fiber treatment agents. It reacts with melamine-formaldehyde (or urea-formaldehyde) resins, epoxy resins, and other materials to produce two-component coatings. Adding it to luxury car paints helps maintain a long-lasting mirror gloss. It can also be used as an adhesive for synthetic textiles and a polymer monomer for medical applications. 2. Used in the production of coatings, automotive topcoats, and primers. It can also be used in photopolymer resins, printing plates, inks, gels (contact lenses), and canned material coatings. It can also be used as an embedding reagent for transmission electron microscopy (TEM) and optical microscopy (LM), particularly for hydrated samples at "sensitive antigenic sites." It is white, watery, viscous, thinner than water, and more permeable than any other resin or monomer. It is particularly useful for working with bone, cartilage, and difficult-to-penetrate plant tissues. 3. Used in the plastics industry to produce reactive hydroxyl-containing acrylic resins. In the coatings industry, it is used in combination with epoxy resins, diisocyanates, and melamine-formaldehyde resins to produce two-component coatings. In the oil and fat industry, it is used as a lubricant detergent additive. In the electronics industry, it is used as a dehydrating agent for electron microscopes. In the textile industry, it is used to manufacture fabric adhesives. In analytical chemistry, it is used as a chemical reagent. Furthermore, it is used in water-miscible embedding agents and in the synthesis of medical polymer materials, thermosetting coatings, and adhesives.
