Product Overview

Morwet D-400 Powder is a sodium alkyl naphthalene sulfonate condensate (NSC) supplied as a free-flowing powder. It is positioned by Nouryon as a cost-effective version of Morwet D-425, offering a lower-cost route to the same anionic dispersant chemistry for formulators who do not require the full performance specification of the D-425 grade. Evergreen Chemicals supplies Morwet D-400 Powder as an authorized Nouryon distributor.

Technical Data

Application

As a sodium naphthalene sulfonate condensate (NSC), Morwet D-400 Powder belongs to a well-established class of anionic dispersants and wetting agents commonly used in agrochemical formulations (wettable powders, suspension concentrates), dye and pigment dispersion, and other water-based formulation systems requiring particle dispersion and wetting performance. Its relatively low surface tension and effective wetting power (Draves ≥5 min) support formulation stability in these systems.

Please contact our technical team to confirm suitability and recommended dosage for your specific formulation, as the manufacturer's data sheet does not specify a dedicated application list for this grade.
