【Product Features and Application】
DISPER RYD 981 is anionic surfactant of conjugated molecular organic phosphate ester amine salt, with high purity phosphate ester dispersant. It excludes APEO, soluble in hot water, and can be applied on middle/low contents of pesticide suspension concentrates (SC), suspension for seed coating agent (FS), suspension emulsion (SE), emulsion (EW)， micro emulsion etc. It can be applied together with polycarboxylate dispersant DISPER D600 or DISPER D1000, can also be used for high content of pesticides and fungicides, especially suitable for herbicide suspension system.
DISPER RYD 981 has bigger conjugate radicle and phosphate diester lipophilic group. Under the action of external force, such as colloid milling or high-speed shearing force, it can effectively work with pesticide particles, improve the emulsifying and dispersing stability of pesticide particles or droplets with water as the continuous phase. Experiments show that this product has certain wetting ability, high cost performance, and can be used alone or with polycarboxylate, also applied on SC, SE, FS, CS, EW, ME, WP, and WDG pesticide preparations, with wetting agent WETTING 900 in a ratio of 3:0.5 and 3-5% usage. It particularly suits for low/medium content of high concentration of herbicide pesticide suspension agent.
