QS-302 Spray Adjuvant is a super-spreading surfactant based on a trisiloxaneethoxylate. This spray adjuvant lowers the surface tension of spray solutions, beyond that which is achievable with conventional adjuvants. Typically this spray adjuvant (@ 0.1 wt %) gives an aqueous surface tension of <22 mN/m. On the other hand, an octylphenolethoxylate containing 10 EO units (a commonly used nonionic surfactant) at 1.0 wt % gives a surface tension of only 30 mN/m. This spray adjuvant helps lower the aqueous surface tension more effectively than conventional spray adjuvants. Because this 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.
