Organosilicone Surfactant

QS-302 is an organosilicone surfactant (Chemical name: Polyalkyleneoxide Modified Heptamethyltrisiloxane ), which can lower the surface tension of spray solutions, and leading to an increase in spray coverage. It promotes rapid uptake of agrochemicals into plants via stomatal infiltration. Spray solutions taken into plants in this way become rain fast.

Organosilicone Specifications

QS-302 spray adjuvant lowers the surface tension of spray solutions, beyond that which is achievable with conventional adjuvants.Typically, QS-302 spray adjuvant (@ 0.1 wt %) gives an aqueous surface tension of <21.5 mN/m. Using in tank mix or EC formulation, which can lower the contact angel between the spray and foliage, which can enlarge the coverage of the spray.

This product can be called agricultural silicone, spray pesticide additives, pesticides extension penetrant. lt is akind of special modified silicone surfactant and has very low surface tension. Achieve rapid wetting, dispersion,and penetration into the pores of the plant and kill pests and improve pesticide effect.
