MORWET EFW POWDER

Morwet EFW Powder delivers rapid wetting and efficient water penetration in powdered agrochemical formulations.
Morwet EFW Powder helps reduce floating, shortens dispersion time, and improves the uniform distribution of active ingredients.
Morwet EFW Powder's strong wetting performance makes it suitable for wettable powders, water-dispersible granules, and suspension-based systems.

Morwet EFW Powder is a sodium alkyl naphthalene sulfonate blend and industy benchmark for outstanding wetting performance.
Morwet EFW Powder is a high-performance anionic surfactant based on a sodium alkyl naphthalene sulfonate blend.

Morwet EFW Powder is recognized for its rapid wetting action, helping water penetrate and disperse powdered active ingredients efficiently.
Morwet EFW Powder is commonly used as a wetting agent in crop-protection and agrochemical formulations.

Morwet EFW Powder supports fast powder hydration, uniform dispersion and improved formulation performance in suspension concentrates (SC), water-dispersible granules (WDG), water-soluble granules (WSG) and wettable powders (WP).
Morwet EFW Powder is generally supplied as a brown powder with high active content and is often combined with dispersants such as Morwet D-425 Powder.

Applications and Uses of Morwet EFW Powder:

Solid Formulations:
Good wetting, dispersing and suspension performance are key requirements of dry formulations.
The Morwet wetting and dispersing agents are an excellent choice when formulating wettable powders (WP) and water dispersible granules (WDG).

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.

Alternative wetting agents to Morwet EFW are Morwet DB (for low active concentration systems), Morwet IP (for reduced foaming) and Morwet 3028 (to improve granule disintegration in high active concentration systems).
As in SCs the lignin/naphthalene sulfonate proprietary process blends, Morwet D-360 and Morwet D-390, can be used to replace specialty lignosulfonates.

Compared to these Morwet D-360 and Morwet D-390 often offer better suspensibility and dispersibility, especially upon storage.
Also in solid formulations, Morwet D-400 is a good and cost effective alternative to Morwet D-425 look-a-likes.

Morwet D-809, our most recent dispersant, allows formulators to produce high performance WDGs in hard water conditions.
In some agro markets there is a strong preference for white WDG.

As Morwet dispersants have a tendency to bring a slightly brownish color to the formulations it is possible to substitute them with either Agrilan 700 or Agrilan 789 (polycarboxylates).
These Agrilan products will ensure equally good performance and a very white looking formulation.

Aqueous Dispersions:
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.

In case better wetting of the active ingredient is required in the premix, addition of Morwet EFW can be considered.
Other good wetting agents for SC applications are of the alcohol ethoxylate type or block copolymer (e.g. Ethylan NS 500 LQ).

These wetting agents can be added at a rate of 1 % w/w.
Morwet EFW Powder is known to provide good formulation stability.
Morwet EFW Powder significantly reduces crystal growth during storage.

Morwet EFW Powder is an excellent dispersant for a wide variety of active ingredients and the product ensures good dispersibility in both soft and hard water.
Alternatively our new high performance dispersant, Morwet D-809, is very effective in hard water applications, even at lower surfactant concentrations.

To substitute specialty lignosulfonates in SCs Nouryon offers two new dispersants: Morwet D-360 and Morwet D-390.
They are proprietary process blends of lignin and naphthalene sulfonates and can be used individually or in combination.

Morwet D-360 and Morwet D-390 show better performance compared to specialty lignosulfonates (e.g. lower viscosity in SC applications).
Another good and cost effective dispersant is Morwet D-400.

Morwet EFW Powder is chemically similar to Morwet D-425 but contains a lower amount of naphthalenesulfonate.
Morwet EFW Powder's performance is comparable to most Morwet D-425 look-a-likes.
