EMULSOL KSIL L-77 Spray Adjuvant
Product Description
EMULSOL KSIL L-77 spray adjuvant is a superspreading surfactant based on a trisiloxane ethoxylate. EMULSOL KSIL L-77 spray adjuvant lowers the surface tension of spray solutions, beyond that which is achievable with conventional adjuvants.Typically, EMULSOL KSIL L-77 spray adjuvant (@ 0.1 wt %) gives an aqueous surface tension of 20.5 mN/m. On the other hand, an octylphenol ethoxvlate 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 L-77 spray adjuvant helps lower the aqueous surface tension more effectively than conventional spray adjuvants.
Key Features and Typical Benefits

Product Description
Because EMULSOL KSIL L-77 spray adjuvant is a superspreading surfactant, the contact angle of spray solutions on lea~ surfaces is reduced, leading to an increase in spray coverage.Additionally, under specific conditions, EMULSOL KSIL L-77 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.
EMULSOL KSIL L-77 spray adjuvant is nonionic in nature, making it useful with a broad range of agrochemical formulations.
How to Use
In Agrochemical FormulationsEMULSOL KSIL L-77 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 EMULSOL KSIL L-77 spray adjuvant be used at a concentration of at least 5%, based on the total formulation.
As A Tank Mix Adjuvant
EMULSOL KSIL L-77 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 L-77 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 EMULSOL KSIL L-77 spray ad¬juvant. In fact, EMULSOL KSIL L-77 spray adjuvant may provide adequate coverage in many low volume spray applications at rates between 0.025% and 0.1%.
Potential Applications
EMULSOL KSIL L-77 spray adjuvant has been used successfully in spray, applications globally. Typical applications include:| Application | Typical Use Rate(a) |
