Agricultural Silicone Synergist RH-208 CAS NO.:67674-67-3
(Similar as Silwet 408,Break Thru S240,Dow Corning Q2-5211,Sylgard 309,Silwet L-77 etc.)
also called as Agricultural Spray Adjuvant,tank-mix adjuvant,Low dose tank mix adjvuants,stickers,spreaders,penetrants,Nonionic Silicone Surfactant, wetting agent,Polyether Modified Trisiloxane,100% Agricultural Organic Silicon,Silicone Synergistic Agent for plant,Agricultural Silicone Spreading and Penetrating Agent
Introduction
RH-208 is 100% Polyether Modified Trisiloxane with super spreading and penetrating property. 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*208 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.
Feature
Agricultural Silicone Synergistic Agent RH-208 has super spreading and penetrating property, high-efficient systemic and conduction property, and tolerance property of rainfall.
Basic Character
Appearance: Colourless to light amber liquid
Surface Tension(0.1%): <20.5mN/m
Density: 1.02g/cm3
Viscosity(25°C): 40-60 mPa.s
Cloud Point: <10°C
Use Area
Agricultural Silicone Spreading and Penetrating Agent can add to the biological pesticide spray mixture liquid such as pesticide, bactericide, herbicide, foliar fertilizer, plant growth regulator, etc, especially applied for systemic pharmacy.
1.Used of spray mixed in drum
In general, add Agricultural Silicone Synergistic Agent RH-208(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%
Herbicide: 0.025%-0.15%
Pesticide: 0.025%-0.1%
Bactericide: 0.015%-0.05%
Fertilizer and trace element: 0.015%-0.1%
When using, first dissolve the pesticide, add RH-208 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.
