Product purpose:
1. Mainly used for modification of resin and coating. By copolymerization with other acrylic monomers, acrylic resin with active hydroxyl groups in the side chain can be prepared, which can be used for esterification and cross-linking reaction, synthesis of insoluble resin and improvement of adhesion, and can be used as fiber treatment agent. It reacts with melamine formaldehyde (or urea formaldehyde) resin and epoxy resin to manufacture two-component coatings. Added to the paint of high-end cars, it can maintain mirror luster for a long time. It can also be used as adhesive for synthetic textiles and medical polymer monomer.
2. used for the production of paints, automotive topcoat and primer resins, and also for photopolymerization resins, printing plates, ink, gel (contact lenses) and tinned material coatings, transmission electron microscope (TEM) and optical microscope (LM) embedding reagent, especially for "sensitive anti in-situ" hydration samples. White water, sticky, thinner than water, more permeable than any resin and monomer. It is especially used for working on bones, cartilage and plant tissues that are difficult to penetrate.
3. The plastic industry is used to manufacture acrylic esters containing active hydroxyl groups. The coating industry and epoxy resin, diisocyanate, melamine formaldehyde resin are used to prepare two-component coatings. The grease industry is used as an additive for lubricating oil washing. The electronic industry is used as a dehydrating agent for electron microscopy. Adhesives used in the textile industry to make fabrics. Used as a chemical reagent in analytical chemistry. In addition, it is also used as water miscible embedding agent for the synthesis of medical polymer materials, thermosetting coatings and adhesives.
