Wetting and Spreading Adjuvant for Agricultural Sprays - WL510

You are here:

WL510 is a super-spreading polyether silicone adjuvant for agricultural spray formulations. It lowers the surface tension of the spray liquid to about 21 mN/m at 0.1%, against a floor of roughly 30 mN/m for conventional non-silicone adjuvants.

Product Detail

Application

Agricultural spray-tank mixtures; confirm compatibility and spray-water conditions before use.

Formulation Type

Agricultural spray-tank mixtures; confirm compatibility and spray-water conditions before use.

Key Benefits

The following functions are described in the published source; they are not measured results for every formulation.

The reduction is dynamic and fast, so the contact area grows as soon as the droplet reaches the leaf. In practice that means better coverage and adhesion, stomatal penetration and the rainfastness that comes with it, at lower spray volumes.

Technical Data

See the technical specifications table above and the source TDS below. Keep the stated units, dosage basis and test conditions together when comparing grades.

How to use it

WL510 disperses readily in water and is added to the spray tank last, with minimal agitation to limit foam. It hydrolyses readily under acidic or alkaline conditions, so buffer the spray mix close to neutral (pH 7.0) and use it immediately rather than leaving it standing overnight. Typical spray-tank use is 0.025%-0.1%; avoid high spray volumes, which only add runoff.

Storage

Store in the original sealed container. Shelf life is 12 months from the date of manufacture.
