    1. This product can irritate eyes, respiratory system and skin.

    2. After contact with skin, rinse immediately with plenty of water.

    3. After contact with eyes, rinse immediately with plenty of water and seek medical advice.

    4. Generally, it is not harmful to water. If no government permits, do not discharge materials into the surrounding environment.


    1. As a dispersant, sodium methacrylate can also be used as an excipient in coatings. Sodium methacrylate is polymerized into sodium polyacrylate, which is a kind of anion polymer dielectric and an important chemical product with wide application.

    2. Sodium polyacrylate includes water-soluble and water-swelling properties, and water-swelling sodium polyacrylate belongs to the category of superabsorbent resin; Another kind of water-soluble sodium polyacrylate is widely used in the fields of food, feed, textile, papermaking, water treatment, petrochemical, agriculture, forestry, horticulture, physiology and health due to its different molecular weight and various properties.

    3. Most sodium polyacrylate was synthesized from acrylic acid after neutralization and polymerization by sodium hydroxide. Other monomers could also be copolymerized with sodium acrylate to modify the properties of sodium polyacrylate and synthesize sodium polyacrylate copolymer with special properties.
