CAS 52255-49-9 Poly(maleic acid-co-acrylic acid) sodium salt (MA-AA.Na) dispersant is phosphorus free, non-toxic, and pollution-free. It is an environmentally friendly chemical additive with excellent chelating and dispersing abilities, strong anti floating and anti staining abilities. It is often used as a dispersant for washing aids, printing and dyeing aids, inorganic slurries, and water-based coatings. MA-AA · Na exhibits significant dispersion effect in the preparation of low viscosity and high solid content slurries.
When used as a washing aid, MA-AA · Na has excellent calcium magnesium chelating ability and calcium carbonate dispersibility, which can increase the cleaning performance of laundry detergent, improve the anti ash deposition and anti dirt re deposition performance of laundry detergent, improve the processing technology of laundry detergent, and have excellent compatibility with inorganic detergents such as zeolite and layered silicon; Has good pH buffering ability, which can reduce the irritation of detergents to the skin; It can improve the performance of powder coating slurry, increase slurry concentration, save energy consumption, increase the smoothness and strength of laundry detergent particles, and reduce the content of fine powder.
The application of MA-AA · Na in textile printing and dyeing processes such as desizing, boiling, bleaching, and dyeing can reduce the impact of metal ions in water on product quality, protect the decomposition of H2O2, and protect fibers. In addition, MA-AA · Na also has a good dispersing effect on printing pulp, industrial coatings, ceramic pulp, paper coating, calcium carbonate powder, etc. It can be applied in textile auxiliaries such as tube yarn cleaning, chelating dispersants, non foaming soaping agents, and leveling agents.
