Super-spreading trisiloxane ethoxylate Surfactant CAS#:67674-67-3
TIS-390 spray adjuvant is a super-spreading surfactant based on a trisiloxane ethoxylate. TIS-390 spray adjuvant lowers the surface tension of spray solutions, beyond that which is achievable with conventional adjuvants.
Typically, TIS-390 spray adjuvant (@ 0.1 wt %) gives an aqueous surface tension of <22 mN/m. On the other hand, an octylphenol ethoxylate containing 10 EO units (a commonly used nonionic surfactant) at 1.0 wt % gives a surface tension of only 30 mN/m.
TIS-390 spray adjuvant helps lower the aqueous surface tension more effectively than conventional spray adjuvants. Because TIS-390 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 .

Usage and dosage
In Agrochemical Formulations
TIS-390 spray adjuvant may be used as a component in agrochemical formulations. Although organosilicone surfactants are subject to hydrolysis under acidic or basic conditions, optimum performance is achieved by buffering the formulation to pH 6.5 - 7.5. Additionally, it is recommended that TIS-390 spray adjuvant be used at a concentration of 0.5-8%, based on the total formulation.
As A Tank Mix Adjuvant
TIS-390 spray adjuvant, when used as a tank-side adjuvant may be used to improve spray coverage, improve uptake or to allow for a reduction in spray volume. TIS-390 spray adjuvant is most effective as a tank-side adjuvant when spray mixtures are 1) within a pH range of 5-8, and 2) used within 24 hours of preparation.
High spray volumes, coupled with high surfactant rates, are not required to achieve sufficient coverage with TIS-390 spray adjuvant. In fact, TIS-390 spray adjuvant has the potential to provide adequate coverage in man
