Polyether Modified Trisiloxane Spreading Agent NK-208
- Commodity name： Polyether Modified Trisiloxane Spreading Agent NK-208
Product Description
Product Introduction
RH-208 agricultural spreading agent is a non-ionic organosilicon surfactant with super spreading and wetting performance. It can reduce the surface tension of the spray solution more rapidly than traditional adjuvants, and reduce the surface tension of water to 20.5mN/m at 0.1% concentration (wt.). It can effectively reduce the contact angle between the spray solution and the leaf surface, thus increasing the coverage of the spray. It can also promote the pesticide absorption through the stomata of the leaf to achieve the resistance to rain wash,thus increasing the effectiveness.

Product Highlights
1. A super spreading agent for solutions and emulsions.
2. Reduce spray use and increase spray coverage.
3. Promote the rapid absorption of pesticides; resistant to rain wash.
4. A non-ionic surfactant.
Applications
1. As a barrel mixing adjuvant: Recommended dosage: 0.01-0.1%, PH: 6.0-8.0, best effect when used within 24 hours.
2. When added in pesticide formulations: Silicone surfactants will be hydrolysed under acidic and alkaline conditions, and it can be regulated by sustained-release agents. The best performance can be achieved at PH 6.5-7.5, and the recommended dosage is 0.1-5%.
Packing, Storage and Transport
Packed in plastic drums, 200kg/drum or 1000kg/drum. Stored and transported as general chemicals.
Application Guidance
Usually 5g of RH-208 spreading agent is added to every 20kg spray solution (4000 times), and it can be used immediately after uniform mixing. If it is necessary to promote the absorption of systemic pesticides, further improve the efficacy of pesticides, or reduce the spray volume, the dosage of RH-208 spreading agent should be increased appropriately.
In general, the dosage is as follows:
|
Item |
Indicator |
|
Plant growth regulator |
0.025%～0.05% |
|
Herbicide |
0.025%～0.15% |
|
Insecticide |
0.025%～0.1% |
|
Bactericide |
0.015%～0.05% |
|
Fertilisers and micronutrients |
0.015～0.1% |
|
Plant growth regulator |
0.025%～0.05% |
First dissolve the pesticide, add 80% water and mix well, then add RH-208 spreading agent, and then add 100% water and mix well. When using RH-208 spreading agent, it is recommended that the amount of water used can be reduced to 1/2 (recommended) or 2/3 of the normal amount, and the amount of pesticide per unit area can be reduced to 70%-80% of the normal dosage. When using nozzles with smaller orifices, the spray rate should be increased appropriately.
