Polyalkyleneoxide Modified Heptamethyltrisiloxane series

Product Name: Polyalkyleneoxide Modified Heptamethyltrisiloxane (SEGA-66)


Polyalkyleneoxide Modified Heptamethyltrisiloxane(SEGA-66) 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 SEGA-66 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



SEGA-66 has super spreading and penetrating property high-efficient systemic and conduction property and tolerance property of rainfall.

Surface Tension(0.1%): <22 mN/m

Density: 1.01-1.03g/cm3

Viscosity(25°C): 20-60 mPa.s

Cloud Point: <10°C


Use Area :

SEGA-66 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


Use Method:

1) Used of spray mixed in drum

In general add SEGA-66 (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 SEGA-66 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..
