Dispersant SP-WG32

DF Adjuvants (Dry Flowable Adjuvants)

(Low Foaming, Milling Aid)

SP-WG32 is a comb-like polycarboxylate dispersant with moderate hydrophobic groups and MW distribution contributed by controllable polymerization technology. This greatly enhances versatility of the dispersant and long-term stability of DF. London dispersion force generated by similarity of hydrophobic groups of SP-WG32 and the groups on active ingredient, and the force formed by hydrogen bonds from the carboxylate groups, imparting irreversible adsorption capabilities to particles during milling and drying process. The spatial hindrance effect of the long carbon chains in the polymer makes SP-WG32a high versatile DF dispersant.

Features

Highly increase milling efficiency by combining with SP-WG30 in Pymetrozine DF.

Significantly improve the heat resistance of formulations and reduce the risk of formation of non-dispersed particles during the production.

Synergy effect realized by using together with SP-WG95. Total dosage can be reduced by over 35% compared to using SP-WG95 alone.

Dosage:

5-25%

40% Pymetrozine + 20% Dinotefuran DF

Challenges of Formulation

Difficult to control the moisture content when spraying due to the high viscosity of slurry

Solution

Using SP-WG32 can significantly improve the heat resistance of formulations in the production of DF. It exhibits remarkable milling aid property and enhances dispersibility of Pymetrozine DF series such as 70% Pymetrozine DF, 70% Pymetrozine + Dinotefuran DF.
