Organosilicone Adjuvant H-8408

H-8408 is a nonionic modified polyether trisiloxane surfactant. It reduces the surface tension of the liquid, reduces the contact angle between the liquid surface and the interface, promotes the surface expansion speed of the liquid medicine and expands the expansion area of the liquid medicine. It can promote the absorption of the chemical solution by the stomata of the leaves, and has super strong adhesion at the same time, so the chemical solution is resistant to rain erosion, which can effectively reduce the waste of the chemical solution and the pollution to the environment.



Product name: Organosilicone adjuvant

1. Add pesticide formula:

When added to the pesticide formula, it is recommended to adjust the pH value of the pesticide formula to 6~8. The dilution ratio of the additive is 1500-6000 times. According to different pesticide varieties and formulations, adjust the amount of silicone additives to achieve the most economical and effective effect. Compatibility tests and drug effect ladder tests should be done before use.

2. Add tank mix spray and use:

Agricultural silicone adjuvants are most effective in tank-mix sprays, and the dilution factor varies according to different silicone adjuvants and for different application ranges. For example, H-8408 silicone adjuvant generally has a tank-mixing dilution factor of 3,000 times, but it should be doubled for weeding after seedlings, fruit tree young fruit stage, and regulators.

When using, first mix the liquid medicine with 80% water, then add silicone additive H-8408 and mix well, then add 100% water and mix well. Reduce the water consumption to 1/2 or 2/3 of the conventional amount, use nozzles with smaller apertures, and speed up the spraying speed appropriately.


Before handling, read the Material Safety Data Sheet and container label for safe use, physical and health hazard information.



After sealing packaging products stored in a cool, dry place , H-8408 has a shelf life of 36 months from date of manufacture.Ship as a non-hazardous chemical.



H-8408  is available in 200L drum and 1000L IBC or others.
