Huawen® SMA resin (styrene maleic anhydride copolymer) offers flexible chemical modification and can be used as a dispersant for inks and coatings, heat-resistant overprint varnishes, and high-pigment-to-base ratio colorants. Chemically modified SMA resins are primarily used as dispersants for coatings and inks to improve wettability, dispersion uniformity, storage stability, and heat resistance. For example, the sodium salt of SMA can be used as a dispersant for pigments, improving their wettability and dispersion.
