  • As a monomer of corrosion and scale inhibitors,this product can be used in water treatment chemicals.It can polymerize with acrylic acid,acrylamide,maleic anhydride,sodium hypophosphite and has good scale inhibition effects for calcium phosphate,zinc salts,carbonate calcium sulfate

  • It can be used as a high-powdered water reducer of poly carboxylic acid to low the water added of products and retard well.

  • As a oil field chemical,it can polymerize with acrylamide,acrylic acid,sodium humate,acrylamido propyl trimethyl ammonium chloride,acrylamido-ethyl-2methyl ammonium chloride,diethyl diallyl ammonium chloride,allyl trimethyl ammonium chloride to be dispersants,fluid loss agent and have remarkable effect in anti-high temperature and salt.

  • As a paint additive,it can be used to produce thermosetting acrylic resin and coating dispersant to increase the water-solubility.

  • As the third monomer of acrylic,it can improve the dyeing properties,the heat resistance and flexibility of fibers,so they can absorb color fast and have strong fastness and bright color.

  • As a mmonomer of flocculant it can polymerize with acrylamide.

  • It can polymerize with methy acrylic acid,itaconic acid to be a dispersant.

  • It can be used to make CPPL and high water-absorbing resin in electronics and materials processing.

  • It can polymerize with sodium acrylat,styrene-acrylic emulsion,polyvinyl alcohol to improve fertilizer about red soil and stengthen absorb ammonium ion,nitrate ion.
