EMULSOL K-SIL 806 Spray Adjuvant
Product Description
EMULSOL KSIL 806 spray adjuvant is a superspreading surfactant based on a trisiloxane alkoxylate. EMULSOL KSIL 806 spray adjuvant lowers the surface tension of spray solutions, beyond that which is achievable with conventional adjuvants.Typically, EMULSOL KSIL 806 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.
The bottom line? EMULSOL KSIL 806 spray adjuvant helps lower the aqueous surface tension more effectively than conventional spray adjuvants.

Product Description
Because EMULSOL KSIL 806 spray adjuvant is a superspreading surfactant, the contact angle of spray solutions on leaf surfaces is reduced, leading to an increase in spray coverage.Additionally, under specific conditions, EMULSOL KSIL 806 spray adjuvant promotes rapid uptake of agrochemicals into plants via stomatal infiltration. Spray solutions taken into plants in this way become rainfast, thereby improving application reliability. The low foam properties of EMULSOL KSIL 806 spray adjuvant may make it easier to handle than other organosilicone based spreading agents. EMULSOL KSIL 806 spray adjuvant is nonionic in nature, making it useful with a broad range of agrochemical formulations.
How to Use
In Agrochemical FormulationsEMULSOL KSIL 806 spray adjuvant may be used as a component in agrochernical formulations. Although organosilicone surfactants are subject to hydrolysis under addle or basic conditions, optimum performance is achieved by buffering the formulation to pH 6.S -7.5. Additionally, it is recommended that EMULSOL KSIL 806 spray adjuvant be used at a concentration of at least 5%, based on the total formulation.
As A Tank Mix Adjuvant
EMULSOL KSIL 806 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. EMULSOL KSIL 806 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 suffident coverage with EMULSOL KSIL 806 spray adjuvant In fact, EMULSOL KSIL 806 spray adjuvant may provide adequate coverage in many low volume spray applications at rates between 0.025% and 0.1%.
Potential Applications
EMULSOL KSIL 806 spray adjuvant has been used successfully in spray applications globally. Typical applications include:
| Application | Typical Use Rate (a) |
