一、 Basic features
Sp-of3498d is a kind of dispersant for polycarboxylate oil suspension concentrate with special structure prepared by controlled polymerization technology. The long side chain of comb structure has good compatibility with methyl oleate or vegetable oil as the carrier of oil suspension agent. The benzene ring or heterocyclic side chain can be firmly adsorbed on the particle surface under the dispersive force, and the polyoxyethylene ether side chain and carboxylate side chain can improve the second time of coated particles in water Dispersion stability. Its properties are better than those of polyalkylsuccinamide or long carbon fatty acid diester oil suspending agent.
二、 Typical data
Yellow liquid appearance: transparent liquid
Moisture: < 0.5%
Density (25 ℃, kg / m3): 927
Solubility in oil: soluble in methyl oleate, vegetable oil and other solvents
Closed flash point (℃): > 100
Kinematic viscosity (MPa. S, 25 ℃): 300-600
Freezing point: 2 ℃
三、 Application characteristics
When the dosage of sp-of3498d is 2-3% in methyl oleate or vegetable oil suspension concentrate system, if the dosage is increased appropriately when special requirements are met, sp-of3498d can be applied to Nicosulfuron, atrazine and single agent or compound agent, which can effectively reduce the viscosity of the preparation system, and can also slow down the paste formation of the preparation. Different sources of methyl ester and crude oil showed good performance. The oil suspension concentrate with sp-of3498d dispersant has low viscosity and good stability over time.
