Equivalent:  Momentive Silwet L-77
Sinnosil ®OF-77 spray adjutant is a super spreading surfactant based on a trisiloxane ethoxylate. Sinnosil ®OF-77 spray adjutant lowers the surface tension of spray solutions, beyond that which is achievable with conventional adjutants. Typically, Sinnosil ®OF-77 spray adjutant (@ 0.1 wt %) gives an aqueous surface tension of 20.5 mN/m. After the mixture with the pesticide solution at the certain proportion, It can lower the contact angle between the spray and foliage, which can enlarge the coverage of the spray. Furthermore, Sinnosil ®OF-77 can make the pesticide absorbed through the stoma of leaves, which is extremely effective for improving efficacy, reducing amount of pesticide,saving cost, reducing environmental pollution caused by pesticides.
