  • Modified aspartate resin and aqueous dispersion
    Patent number: 12637533
    Abstract: Disclosed are a modified aspartate resin and an aqueous dispersion, which relate to the technical field of aqueous emulsion. The modified aspartate resin is obtained by reacting a hydrophilic aspartate resin with a polyisocyanate compound, followed by reaction with a hydrophobic aspartate resin. The modified aspartate resin exhibits moderate hydrophilicity, enabling self-emulsifying dispersion in water to form an aqueous dispersion. The film formed from the aqueous dispersion after curing shows good water resistance.
