Silicone Surfactant for agriculture QS-302B Description

QS-302B Silicone surfactant

is a super- spreading adjuvant , the contact angle of spray solutions on leaf surfaces is reduced, leading to an increase in spray coverage .

Additionally, under specific conditions, QS-302B 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.

Unlike other trisiloxane alkoxylates, which are negatively affected by oil based components (i.e. EC formulations, spray oils, etc.), QS-302B spray adjuvant provides enhanced spreading in many of these types of formulations relative to competitive organosilicone based adjuvant.
QS-302B spray adjuvant is nonionic in nature, making it useful with a broad range of agrochemical formulations.

How to use

In Agrochemical Formulations
QS-302B silicone surfactant 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 QS-302B spray adjuvant be used at a concentration of 0.5-8%, based on the total formulation.

As A Tank Mix Adjuvant
QS-302B 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. QS-302B spray adjuvant is most effective as a tank-side adjuvant when spray mixtures are within a pH range of 5-8, and used within 24 hours of preparation.

High spray volumes, coupled with high surfactant rates, are not required to achieve
sufficient coverage with QS-302B spray adjuvant.

In fact, QS-302B spray adjuvant has the potential to provide adequate coverage in many low volume spray applications at rates between 0.025% and 0.1%.
