Chemical name: Polyether modified siloxane fluid

CAS No: 134180-76-0

Super Silicone Spreader RJ-7000 is a new polyether modified silicone surfactant with very low surface tension in aqueous solution,which haS much better wetting effect than any other traditional silicone surfactants. It’s an organosilicone adjuvant, with super spreadability and penetrability, can be used as surfactant in tank mixture with agrochemicals to improve their performance. It can also be formulated in producing process as additive.

It’s a nontoxic, environmentally friendly product, and can help farmers reduce the using amount of fungicides, herbicides, insecticides and other plant protection chemicals.

Silicone Spreader RJ-7000 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 RJ-7000 according to different varieties and condition, in order to achieve the most cost-effective results.

The tank-mix: 

As a tank mix additive, RJ-7000 can improve spray coverage, promote absorption, and reduce the amount of spray. When spray mixture PH is 5-8, and used within 24 hours after preparation, RJ-7000 performs best.

In fact, usually 0.025%-0.1% RJ-7000 added in the low spray volume can achieve sufficient coverage. Typical usage is as follows: 

Plant Growth Regulator   0.025-0.05%
Herbicide  0.025-0.15%
Pesticides    0.025-0.1% 
Antiseptic       0.015-0.05%  
Fertilizers and trace elements    0.015-0.1%                                       


Silicone Spreader RJ-7000 is available in 200kg plastic drums, 1000kg IBC drums or other packing on request.
