Description

Modified heptamethyltrisiloxane spray adjuvant is a high superspreading surfactant modified by trisiloxane ethoxylate with super low surface tension. It lowers the surface tension of spray solutions, beyond that which is achievable with conventional adjuvants.

HOW TO USE

IN AGROCHEMICAL FORMULATIONS

-WET-618 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 WET-618 spray adjuvant be used at a concentration of at least 5%, based on the total formulation.

A TANK MIX ADJUVANT

-WET-618 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. WET-618 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 WET-618 spray adjuvant. In fact, it has the potential to provide adequate coverage in many low volume spray applications at rates between 0.025% and 0.1%.
