Agricultural Silicone Surfactant RH-209
Product Name：Agricultural Silicone Surfactant RH-209
Polyalkyleneoxide Modified Trisiloxane
Like products: Silwet L-77
Agricultural Silicone Surfactant RH-209 is a modified Trisiloxane, and is an organic silicone surfactant with super ability of spreading. It makes the water surface tension lower down to the 20.5mN/m at the concentration of 0.1%(wt.). After the mixture with the pesticide solution at the certain proportion, it can lower the contact angel between the spray and foliage, which can enlarge the coverage of the spray. Furthermore, Runhe*209 Agricultural Silicone Spreading and Penetrating Agent can make the pesticide absorbed through the stomatal of leaves, which is extremely effective for improving efficacy, reducing amount of pesticide, saving cost, reducing environmental pollution caused by pesticides
Agricultural Silicone Surfactant RH-209 is a super spreader and sticker.
Appearance: Colourless to light amber liquid
Surface Tension(0.1%): <21.0mN/m
Viscosity(25°C): 15-30 mPa.s
Cloud Point: <10°C
Use Area :
RH-209 can add to the agrochemicals spray mixture liquid such as pesticide, bactericide, herbicide, foliar fertilizer, plant growth regulator, etc, especially applied for systemic pharmacy.
Without RH-209 With RH-209
1) Used of spray mixed in drum
In general, add Agricultural Silicone Surfactant RH-209(4000times) 5g in every 20kg spray. If it needs to promote the adsorption of systemic pesticide, increase the function of pesticide or reduce the amount of spray further, it should add the usage amount properly. In general, the amount is as follows:
Plant promote regulator: 0.025%-0.05%
Fertilizer and trace element: 0.015%-0.1%
When using, first dissolve the pesticide, add RH-209 after the uniform mixture of 80% water, then add water to 100% and mix them uniformly. It is advised that when using Agricultural Silicone Spreading and Penetrating Agent, the water amount reduced to 1/2 of the normal (suggested) or 2/3, average pesticide usage reduced to 70-80% of the normal. Using the small aperture nozzle will quicken the spray speed.
2) Used of Original Pesticide
When the product added to the original pesticide, we suggest the amount is 0.5%-8% of the original pesticide. Adjust the PH value of the pesticide prescription to 6-8. The user should adjust the amount of Agricultural Silicone Spreading and Penetrating Agent according to different kinds of pesticide and prescription to reach the most effective and most economical result. Do compatibility tests and stepwise tests before usage..
