1. Mainly used in powder coatings, but also used in thermosetting coatings, fiber treatment agents, adhesives, antistatic agents, vinyl chloride stabilizers, rubber and resin modifiers, ion exchange resins and adhesives for printing inks.
2. Used as a functional monomer for polymerization. Mainly used in the manufacture of acrylic powder coatings. It is used to copolymerize soft monomers with hard monomers such as methyl methacrylate and styrene. It can adjust the glass transition temperature and flexibility, and improve the gloss, adhesion and weather resistance of the coating film. Wait. It is also used in the manufacture of acrylic emulsions and nonwovens. As a functional monomer, it can be used in the manufacture of photosensitive resins, ion exchange resins, chelating resins, medical selective filtration membranes, dental materials, anticoagulants, and non-soluble adsorbents. It is also used to modify polyolefin resins, rubbers and synthetic fibers.
Store in a cool, ventilated warehouse. Keep away from fire and heat sources. The storage temperature should not exceed 30 ℃. Keep away from light. It should be stored separately from acids and oxidants, and must not be mixed. Use explosion-proof lighting and ventilation facilities. Prohibit the use of spark-prone machinery and tools. The storage area should be equipped with spill emergency treatment equipment and suitable containment materials.
