Product Features
  • Anionic naphthalene sulphonate condensates used as primary dispersant.
  • Benchmark to achieve short milling time and low viscosity premix.
  • Brings electrostatic stabilization and makes the formulation stable towards temperature changes.
  • Generally Morwet D-425 can be used to formulate water based suspensions (SC).
  • At 2-3% w/w for a 480 g/l SC and 3-5% w/w for a 720 g/l SC, Morwet D-425 will act as wetting and dispersing agent as well as milling aid.
  • Morwet D-425 is known to provide good formulation stability.
  • It significantly reduces crystal growth during storage.
  • Morwet D-425 is an excellent dispersant for a wide variety of active ingredients and the product ensures good dispersibility in both soft and hard water.
  • Combining the wetting properties of Morwet EFW with the dispersing characteristics of Morwet D-425 is generally the best option.
  • In WP formulations it is recommended to use 1-2% of Morwet EFW and 2-3% of Morwet D-425.
  • For WDG applications the required concentrations will be slightly higher: 2-3% of Morwet EFW and 3-5% of Morwet D-425.
