QS-302 Silicone surfactant uses for agriculture

QS-302 organosilicone is a super-spreading surfactant based on polyether Modified Trisiloxane. 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.

Product description

Product Description:

QS-302 is a super-spreading surfactant based on a Polyether Modified Trisiloxane. It is an organosilicone surfactant, 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.
