Product Description
1. DMAPS is a white crystalline amphoteric monomer with a freely polymerizable methacrylic acid double bond. It has excellent water solubility and is stable in a wide pH and high salt environment without precipitation.
2. After copolymerization, a strong hydration layer forms on the surface of the polymer, significantly inhibiting the adsorption of proteins and microorganisms, achieving anti-fouling, anti-coagulation, and low bioadhesion effects.
3. The core is used for the modification of water treatment nanofiltration / reverse osmosis membranes, the coating of medical implant devices, chromatographic fillers, hydrophilic adhesives, and biological hydrogel materials.
