【Features and Application】

DISPER RYD 982 is an acid anionic dispersant widely used for triazole and urea types of pesticide suspension concentrates (SC), suspension for seed coating agent (FS), suspension emulsion (SE), emulsion (EW), micro emulsion (ME), dry Flowable (DF) Oil dispersion(OD). DISPER RYD 982 can be applied together with polycarboxylate dispersant DISPER D600 or DISPER D1000, and high content of SC pesticide formulation.
DISPER RYD 982‘s big conjugate macromolecular structure can increase the charge density. Under the action of external force, such as colloid milling or high-speed shearing force, it can firmly absorb on the pesticide particle surface, effectively promote quick dispersion of pesticide active ingredients in aqueous system, to form a double stable effect of steric hindrance and Like charges repelling, and improve the storage stability of the product. It has wide adaption of water quality and temperature changes, and improve the emulsifying and dispersing stability of pesticide particles or droplets with water as the continuous phase. DISPER RYD 982 can be used alone or with polycarboxylate(DISPER D600/DISPER D1000), applied on SC, SE, FS, CS, EW, ME, OD and other pesticide preparations, especially suitable for preparation of azole/urea types of suspension for seed coating(FS) or suspension concentrate(SC) which are easy to get creaming. It also suits methyl oleate system as acid dispersant.
