Nicosulfuron + Atrazine
Due to quality fluctuation of Nicosulfuron, Nicosulfuron + atrazine is prone to viscosity increase or creaming problems, and suffers from sedimentation and layer separation during long-term storage, making it difficult to use.
However, the use of dispersing agent SP-OD488 can effectively reduce the viscosity of the formulation, inhibit crystal growth, and effectively delay the occurrence of gelling.

Description
SP-OD488 is a polymeric surfactant with comb structure, copolymerized using unsaturated monomers. Its highly solvated side chain maintains the compatibility of the particles and continuous phase. At the same time, the high charge density of side chain enhances its multiple-point adsorption to particle surfaces. The product is designed to be used in combination with SP-OD422 Emulsifier to facilitate the grinding process and improve the stability of formulations.
Application
Reduces OD viscosity and benefits for producing high loading OD.
Compatible with methyl oleate and vegetable oils.
Dispersant and stabilizer for methyl oleate based OD with dosage 5-8%.
