Description
CAS No: 67674-67-3
TPD-350P is a powdered silicone surfactant which the active content is alkoxy modified solidified polymeric trisiloxane, it has a super spreading force. TPD-350P can reduce the surface tension of spray solution much more than conventional additives. It can make the water surface tension lower down to the 20.5mN/m at the concentration of 0.2%(wt.) As TPD-350P is a super spreading surfactant, it can reduce the contact angle between spray solution and leaf area, thus increasing the coverage of spray. In addition, TPD-350P can promote the absorbability of pesticides through leaf stomata, and spray solution can be easily absorbed by plants through this way to resist rain wash, thus improving the reliability of use. It is a powdery solid product that is very convenient to add to solid pesticides and solidified leaf-surface fertilizers.
Features
- Powder form, easy to use
- Good reliability
- Super spreading and wetting ability
- Good scouring resistance
- Excellent penetrating performance
- Lower use levels than non-silicone surfactants

Application
Solid pesticides
Reduce surface tension and promote effect after being added to WP, GR, WDG, SP, Effervescent agent, etc.
Solid leaf-surface fertilizers
Reduce surface tension of spray solution, saving water and work.
Dosage
It is recommended to add TPD-350P evenly to the pesticides or fertilizer formula in thepowder dosage form in an amount of 0.5-8% of the total amount. It is recommended toadjust the pH value of the pesticide formula to 6-8. Adjust the dosage of silicone additives according to different formulas to achieve the most economical and effective effect. Compatibility tests and pilot ladder tests should be conducted before use.
