H-806 Agriculture Super spreader

Product Specification

CAS:134180-76-0

DESCRIPTION

H-806 Spray Adjuvant is a superspreading surfactant based on a trisiloxane alkoxylate. H-806spray adjuvant lowers the surface tension of spray solutions, beyond that which is achievable with conventional adjuvants.

Typically, H-806spray 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? H-806spray adjuvant helps lower the aqueous surface tension more effectively than conven tional spray adjuvants

Because H-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 (Figure 1).

USES AND APPLICATION

H-806spray adjuvant has been used successfully in spray applications globally. Typical applications include

(a) Note: use rates are dependent on crop, agrochemical and spray volume requirements.

In Agrochemical Formulations

H-806 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 Silwet 806 spray adjuvant be used at a concentration of at least 5%, based on the total formulation.

As A Tank Mix Adjuvant

H-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. H-806spray 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 H-806spray adjuvant. In fact, H-806spray adjuvant may provide adequate coverage in many low volume spray applications at rates between 0.025% and 0.1%.
