Hexamethyldisiloxane Manufacturer introduced that silicone additives mainly include the following three excellent properties: wettability, expandability, and permeability.
1. Good wettability
Plant leaves stems and insect skin surfaces often have anti-wetting components or structures, and the leaf surfaces are often negatively charged, which repels pesticide liquids. Generally speaking, when the surface tension of the spray liquid is lower than the surface tension of the leaves, the spray liquid will adsorb and wet on the surface of the plant. On the contrary, the spray liquid will shrink and gather on the surface of the plant, and the droplets sprayed on the surface of the target object will roll-off.
The surface tension of organic silicon additives is extremely low, and they can easily wet almost all kinds of plant leaf surfaces and pest epidermis, greatly improve the coverage and contact surface of the target organisms by the liquid medicine, reduce the loss of pesticides, and improve their utilization efficiency.
2. Super scalability
Silicone additives have super-expanding performance. After adding the additives, the expanded area is more than 10 times the area of pure water. This performance can make the sprayed chemical liquid cover and adhere to the leaf surface in the largest area, and even reduce The medicament can enter the pests hidden in the back of the leaves or in the crevices of fruit trees, so as to achieve the purpose of direct contact with the medicament solution and even killing of harmful organisms.
3. Excellent permeability
The stoma is one of the main ways for the medicine to enter the plant. The organic silicon additives can effectively promote the penetration of the medicine into the epidermis through the stomata, and the absorption rate is very fast. Studies have reported that silicone additives have a good synergistic effect on abamectin, which is mainly reflected in its ability to make the liquid medicine enter the microscopic pest hiding place, and secondly, it is absorbed by the leaf surface and enters the plant epidermis, prolonging the effect of the medicine. The residual effect period and this residual effect period are longer than the residual effect period brought by mineral oil additives.
