The Screening of Dispersants in Seed Coating Formulations

The delamination caused by the aggregation of particles can be avoided by dispersant. Four dispersant from twenty eight types of domestic dispersant were selected for 20% carbofuran·thiram SCF, 26% thiram·carbendasim·tolclofos methyl SCF and 20% carbofuran·carbendasim·tolclofos methyl SCF. The results of accelerated experiments in the condition of (54±2)℃ showed that the dispersant 16# can improve the suspension stability of the three formulations at the mass fraction of 6.0%,4.0% and 5.0%.
