High Quality Polyalkyleneoxide Modified Heptamethyltrisiloxane CAS 27306-78-1
Product Description

Product Name: Silicone agrochemical super wetting agent
Chemical Name
Polyalkyleneoxide modified heptamethyltrisiloxane
Molecular Formula (C2H4O)nC11H30O3Si3
CAS Number 27306-78-1
As an agricultural silicone additive, it is a silicone polyether nonionic surfactant with low molecular weight, used to improve
the wetting, dispersing and penetrating properties of pesticides, especially aqueous broadleaf herbicides, insecticides and plant
growth regulators. Performance.
Test Items

This is a unique surfactant designed to improve the spreading and wetting properties of pesticide spray mixes. It utilizes unique organosilicon chemistry which provides the most complete coverage possible. It can improve cuticular penetration of plant surfaces by the spray mix. Optimum application and resultant effects can be influenced by many factors.

For direct addition in pesticide formulations, the components can be added directly as a formulation. It is stable in neutral aqueous formulation (pH=7), but degrades rapidly in acidic or alkaline formulations. Super wetting agents can be mixed before use to improve the biological properties of the spray. It can be added to the pesticide formula or to the tank spray.
Add pesticide formula: It is recommended to add 0.5-8% of the pesticide stock solution. It is recommended to adjust the pH of the pesticide formula to 6-8. Add to the tank spray method: Usually add 50 grams of H-77 (4000 times) per 200 kg of spray.

Under normal circumstances, different application fields and corresponding addition parameters are as follows:
Plant growth regulator
Fertilizer and microelement
Packing and Storage
Packing In 200kg net Iron drum or IBC drum
Storage Avoid contact with substances that can trigger its chemical reaction, such as acid, alkali, oxidant, etc., to prevent denaturation. Keep tightly closed. Store in a cool dry place
