Silicone Spreading and Penetrating Agent TPD-377N is is a modified trisiloxane and is an organic silicone surfactant with super spreadability. It makes the water surface tension lower down to 20.5mN/m at the concentration of 0.1%(wt.). After the mixture with the pesticide solution at a certain proportion, it can lower the contact angel between the spray and foliage, which can enlarge the coverage of the spray. Furthermore, TPD-377N can make the pesticide absorbed through the stomatal of leaves, which is extremely effective for improving efficacy, reducing amount of pesticide, saving cost, reducing environmental pollution caused by pesticides.
- Low surface tension, super spreadability and penetrability
- Reduce the dosage of agrichemical spraying agent.
- Increase the coverage of the agrichemicals
- Promote the rapid uptake of the agrichemicals
Item Typical Value Appearance Colorless to light amber liquid Surface tension (0.1%) ＜21mN/m Active content 100% Viscosity(mm2/s ,25℃) 10~30 Cloud point（1% in water solution) < 10℃ Ionic type Nonionic Solubility soluble in water ,alcohol, ether，ketone，etc
Used as spray adjuvant
TPD-377N can increase the coverage of the spraying agent, promote the uptake and decrease the dosage of the spraying agent.It is the most effective when spray mixtures are within a PH range of 6-8 and preparing the spray mixture for immediately use or within 24h preparation.
Used in agrichemical formulations
TPD-377N can be added in the original pesticide.
1) Used in spray mixed in drum
In general, add TPD-377N 5g in every 20kg spray (4000times). If it needs to promote the adsorption of systemic pesticide, increase the function of pesticide or reduce the amount of spray further, the usage amount should be added properly. In general, the amount is listed as follows:
Plant promote regulator 0.025%～0.05% Herbicide 0.025%～0.15% Pesticide 0.025%～0.1% Bactericide 0.015%～0.05% Fertilizer and trace element 0.015～0.1%
When using, firstly, dissolve the pesticide, add TPD-377N after the uniform mixture of 80% water, then add water to 100% and mix them uniformly. It is advised that when using TPD-377N, the water amount reduced to 1/2 of the normal (suggested) or 2/3, average pesticide usage reduced to 70-80% of the normal. Using the small aperture nozzle will increase the spray speed.
2) Used in original pesticide
When the product added to the original pesticide, we suggest the amount is 0.5%-8% of the original pesticide. Adjust the PH value of the pesticide prescription to 6-8. The user should adjust the amount of Silicone Spreading and Penetrating Agent TPD-377N according to different kinds of pesticide and prescription to reach the most effective and most economical results. Do compatibility tests and stepwise tests before use.
