Dispersant SP-WG30

DF Adjuvants (Dry Flowable Adjuvants)

(Lignin Sulfonate with Low Sugar Content and Robust Dispersion Ability)

SP-WG30 is a kind of lignosulfonate dispersant with MW around 10,000 and sulfonation degree of 1.0. Its high molecular weight and low sulfonation degree makes it an ideal DF dispersant that exhibits better adsorption property for active ingredient at high temperature.

Features
Lignosulfonate contains low sugar used in DF, avoiding issue of moisture absorption which normally exhibits poor flowability of finished goods.
Uniform molecular weight distribution gives improved dispersion stability to DF such as 70% Imidacloprid DF shows increased high temperature resistance from 130°C to 150°C, compared to regular lignin dispersant.

Dosage
5-20%

70% Imidacloprid DF

Challenges of Formulation

Prone to the formation of non-dispersed particles and challenging to control moisture content of finished goods.

Solution

Introducing SP-WG30 in the production of DF, it significantly aids the milling, enhances the heat resistance ability of formulation, eventually makes moisture control easier.
