QS-308 spray adjuvant is a super-spreading surfactant based on a trisiloxane ethoxylate. vf-308 spray adjuvant lowers the surface tension of spray solutions, beyond that which is achievable with conventional adjuvants.
Typically, vf-308 spray adjuvant (@ 0.1 wt %) gives an aqueous surface tension of vf-308 spray adjuvant helps lower the aqueous surface tension more effectively than conventional spray adjuvants. Because vf-308 spray adjuvant is a super-spreading surfactant, the contact angle of spray solutions on leaf surfaces is reduced, leading to an increase in spray coverage (Figure 1).
Additionally, under specific conditions, vf-308 spray adjuvant promotes rapid uptake of agrochemicals into plants via stomatal infiltration. Spray solutions taken into plants in this way become rain fast, thereby improving application reliability (Figure 2).
Unlike other trisiloxane alkoxylates, which are negatively affected by oil based components (i.e. EC formulations, spray oils, etc.), vf-308 spray adjuvant provides enhanced spreading in many of these types of formulations relative to competitive organosilicone based adjuvants (Figure 3).

vf-308 spray adjuvant is nonionic in nature, making it useful with a broad range of agrochemical formulations.
