Morwet D 809 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-performance anionic surfactant based on the sodium salt of a naphthalene sulfonate condensate.
Morwet D 809 functions primarily as a dispersing agent and milling aid, helping solid active ingredients remain uniformly distributed in aqueous formulations.
Morwet D 809's relatively high molecular weight provides strong particle stabilization, effective dispersion and good performance under hard-water conditions.
Morwet D 809 is commonly used in suspension concentrates (SC), water-dispersible granules (WG/WDG), water-soluble granules (WSG), wettable powders (WP) and suspoemulsion (SE) formulations.
Morwet D 809 is generally supplied as a brown, water-soluble powder and is especially suitable for agricultural chemical formulations requiring improved suspension stability, reduced agglomeration and consistent processing performance.
Applications of Morwet D 809:
Morwet D 809 can be used to formulate Suspension Concentrate (SC), Water Dispersible Granule (WG), Wettable Powder (WP), and Suspenoemulsion (SE) products.
Morwet D 809 may also be used as an emulsifier for microencapsulation processes.
Morwet D 809 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.
Morwet D 809 Powder is used as a high-performance dispersing agent and milling aid in agricultural chemical formulations.
Morwet D 809 helps distribute solid active ingredients uniformly, prevents particle agglomeration, improves suspension stability and supports efficient grinding or milling processes.
Morwet D 809 is especially suitable for formulations prepared or diluted with hard water.
Common applications include:
Suspension concentrates (SC)
Water-dispersible granules (WDG/WG)
Water-soluble granules (WSG)
Wettable powders (WP)
Pesticide and agrochemical formulations
High-performance formulations requiring good hard-water tolerance
Morwet D 809 may also help reduce formulation viscosity and maintain consistent particle dispersion during storage and application.
