È un tipo di liquido copolimero siliconico polietere a bassa viscosità utilizzato per migliorare le prestazioni di bagnatura, diffusione e penetrazione dei prodotti chimici agricoli. Può essere utilizzato come ingrediente di formulazione in erbicidi e insetticidi a foglia larga solubili in acqua, fungicidi e regolatori della crescita delle piante o come adiuvante in vasca/miscela per prodotti chimici applicati fogliari. 

Spettacoli

SW-253 Silicone Surfactant reduces the surface tension of aqueous agricultural mixtures significantly lower than is achievable with conventional nonionic surfactants. At concentrations as low as 0.01 percent, SW-253 Silicone Surfactant reduces surface tension below 23 dynes/cm, which produces very rapid wetting and spreading on hard-to-wet surfaces such as waxy leaves.

In addition to the rapid wetting and spreading, SW-253 Silicone Surfactant also greatly increases the uptake of chemicals into plant tissues. Adding SW-253 Silicone Surfactant to a herbicide tank-mix may significantly enhance its efficacy, particularly in the control of broadleaf weeds with water-soluble herbicides. The rapid uptake produces “rainfastness”; i.e., herbicides are not washed off by rainfall because they have penetrated into the plant surface.

Come utilizzare nelle formulazioni chimiche agricole

SW-253 Silicone Surfactant may be used as an ingredient in formulations, provided all the ingredients are compatible. SW-253 Silicone Surfactant is stable in neutral aqueous formulations (pH=6.5-7.5), but will degrade rapidly in acidic or alkaline formulations. New product formulations should be thoroughly tested for performance and shelf stability before entering market.

Vita utile e conservazione

When stored below 40°C (104°F), SW-253 Silicone Surfactant has a shelf life of 36 months from date of manufacture.
