Silicone Agricultural Adjuvant RJ-7033(Nonionic silicone surfactant for agriculture) is trisiloxane modified silicone surfactant. It's a generally used product, with it's super spreadability and penetrability, can be used as spray adjuvant with agrochemicals to improve their performance.
This super-spreader could decrease the surface tension of liquid fiercely, making them wet the foliar surface quickly and compeletely. RJ-7033 is also particularly effective in preventing ingredient from being washed by rain(rainfast).

Note of Use
RJ-7033 can be used as a component of 0.5~8% in agrochemical formulations. Proposing of formulations pH value is 6~8. Users should adjust the usage of nonionic silicone surfactant according to different varieties and condition, in order to achieve the most cost-effective results. Prior to the use, compatibility testing and pilot ladder testing should be done.
The tank-mix:
As a tank mix additives, wetting agent RJ-7033 can improve spray coverage, promote absorption, and reduce the amount of spray. If the spray mixture PH is 5-8, and used within 24 hours after preparation, this silicone surfactant would act well.
Usually we add 0.025% -0.1% silicone surfactant in the low spray volume to achieve sufficient coverage.
The typical usage is as follows:
Packing
RJ-7033 is available in 200kg plastic drums, 1000kg IBC drums or other packing on request.
Storage
Transport as non-hazardous chemicals. Store in original container only.
Keep container tightly closed and store in cool, well ventilated place.
Shelf life
Shelf life: 1 years.
