Applications and Uses of Morwet D 245 Liquid:
Morwet D 245 Liquid is primarily used as a dispersing agent in aqueous formulations containing insoluble solid particles.
Morwet D 245 Liquid is widely applied in agricultural suspension concentrates, wettable powders, water-dispersible granules, seed-treatment formulations, and pesticide dispersions.

Morwet D 245 Liquid helps reduce particle agglomeration, lower premix viscosity, improve grinding efficiency, and maintain uniform particle distribution during storage and application.
Morwet D 245 Liquid may also be used in pigments, dyes, coatings, and other industrial water-based dispersions where stable suspension and effective particle stabilization are required.

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 245 Liquid is generally the best option.
In WP formulations Morwet D 245 Liquid is recommended to use 1-2 % of Morwet EFW and 2-3 % of Morwet D 245 Liquid.
For WDG applications the required concentrations will be slightly higher: 2-3 % of Morwet EFW and 3-5 % of Morwet D 245 Liquid.

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 245 Liquid 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 Morwet D 245 Liquid 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 of Morwet D 245 Liquid:
Generally Morwet D 245 Liquid 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 245 Liquid 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 D 245 Liquid is known to provide good formulation stability.
Morwet D 245 Liquid significantly reduces crystal growth during storage.

Morwet D 245 Liquid 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 D 245 Liquid is chemically similar to Morwet D 245 Liquid but contains a lower amount of naphthalenesulfonate.
Morwet D 245 Liquid's performance is comparable to most Morwet D 245 Liquid look-a-likes.
