Morwet D-809 Powder is a higher molecular weight version of Morwet D-425.
The increased molecular weight provides added tolerance to harder water and provides excellent performance at lower use concentrations than the typical naphthalene condensate.
Morwet D-809 Powder is a high-molecular-weight anionic dispersing agent based on the sodium salt of a naphthalene sulfonate condensate.
Morwet D-809 Powder provides strong electrostatic stabilization of solid particles, helping reduce agglomeration, control viscosity, and maintain uniform dispersion in aqueous agricultural formulations.
Compared with conventional naphthalene sulfonate condensates, Morwet D-809 Powder's higher molecular weight offers improved tolerance to hard water and effective performance at lower use concentrations.
Morwet D-809 Powder is suitable for suspension concentrates, water-dispersible granules, wettable powders, suspoemulsions, and microencapsulation processes requiring reliable dispersion and formulation stability.
Applications of Morwet D-809 Powder:
Morwet D-809 Powder can be used to formulate Suspension Concentrate (SC), Water Dispersible Granule (WG), Wettable Powder (WP), and Suspenoemulsion (SE) products.
Morwet D-809 Powder may also be used as an emulsifier for microencapsulation processes.
Morwet D-809 Powder can be used in combination with comb polymer stabilizers, such as Agrilan® 755, or block copolymers, such as Ethylan® 324, or Ethylan® NS-500LQ, to maximize the stability of SC and SE formulations.
