Description
Chemical name: Polyalkyleneoxide Modified Trisiloxane
Cas No: 27306-78-1
Equivalent Product: Momentive Silwet L-77
Silicone Adjuvant For Agriculture TPD-377 is a modified trisiloxane, and is an organic silicone surfactant with super ability of spreading. It makes the water surface tension lower down to the 20.5mN/m at the concentration of 0.1%(wt.). After being mixed 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, Silicone Agricultural Spreading and Penetrating Agent TPD-377 can make the pesticide absorbed through the stomatal of leaves, which is extremely effective for improving efficacy, reducing amount of pesticide, saving cost and reducing environmental pollution caused by pesticides.
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 efficacy
- Better spray treatment adhesion on crop and plant surfaces
- Rainfastness to lower pesticide wash-off and waste
- Lower use levels than non-silicone surfactants

How to use
- Used as a component in agrochemical formulations
When TPD-377 be added to agrochemical formulations, the recommended dosage amount is 0.5%-8%. Adjust the PH value of the formulations to 6-8. Users should adjust the dosage amount of TPD-377 according to different varieties and condition in order to achieve the most cost-effective results.
- Used as a tank mix additive
As a tank mix additive, TPD-377 can improve spray coverage, promote absorption, and reduce the amount of spray. When spray mixture PH is 6-8, and be used within 24 hours after preparation, TPD-377 performs best.
In fact, usually 0.025%-0.1% TPD-377 added in the low spray volume can achieve a sufficient coverage. Typical usage amount is listed as follows:
Plant Growth Regulator 0.025%-0.05% Herbicide 0.025%-0.15% Pesticide 0.025%-0.10% Bactericide 0.015%-0.05% Fertilizers and trace element 0.015%-0.10%
