Technical Data Sheet
JohnHo* 247
spray adjuvant (Resist Hydrolysis)
SPECIALTY FLUIDS - AGRICULTURE
CAS No. 27306-78-1
Description
JohnHo 247 spray adjuvant is a
polyether trisiloxane. In aqueous solutions, it gives super spreading and does dramatically reduce
surface tension.
Typically, JohnHo 247 spray adjuvant reduces the surface tension of
aqueous agricultural mixtures
significantly. At concentrations as low as 0.1 percent, JohnHo 247 spray adjuvant reduces surface tension
below 22 mN/m, which produces very rapid wetting and spreading on hard-to-wet surfaces such as waxy leaves.
JohnHo 247 spray adjuvant is
nonionic in nature, making it useful with a broad range of agrochemical formulations.
Typical Applications
. Crop protection products
. Herbicides
. Insecticides
. Fungicides
. Nutrients and plant growth regulators
Key Features
. Superspreading for exceptional spray coverage of crop and plant surfaces
. Up to 70% spray volume reduction to lower water use and application costs
. Excellent penetration providing better pesticide uptake and efficiency
. Better spray treatment adhesion on crop and plant surfaces
. Rain rinsing resistance to lower pesticide wash-off and waste
. Lower use levels than non-silicone surfactant
. Nonionic
Typical Physical Properties
Property | Result |
Surface Tension (0.1%, mN/m) | 20.5 |
Cloud Point (0.1 wt%, ℃) | <10 |
Viscosity (cSt, 25℃) | 20 |
Specific Gravity (25/25 ℃) | 1.007 |
Usage
. JohnHo 247 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 JohnHo 247 spray adjuvant be used at a
concentration of at least 5%, based on the total formulation.
. JohnHo 247 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. JohnHo 247 spray adjuvant is most effective as a tank- side adjuvant when spray mixtures are used within 12 hours of preparation.
. JohnHo 247 spray adjuvant has been used successfully in spray applications globally. Typical applications include:
Packing
200L or IBC tank
Storage
Being storage in closed containers
Shelf Life
36 months
Application | Typical Use Rate* |
Plant Growth Regulators | 0.025% to 0.05% |
Herbicide | 0.025% to 0.15% |
Insecticide | 0.025% to 0.1% |
Fungicide | 0.015% to 0.05% |
Fertilizers and Micronutrients | 0.015% to 0.1% |
* Note: use rates are dependent on crop,
agrochemical and spray volume requirements
