HY-8328 Polyether-Modified Heptamethyltrisiloxane
HY-8328 is a highly active organosilicone specialty surfactant, chemically known as polyether-modified heptamethyltrisiloxane. This product has low surface tension and excellent wetting, spreading, penetration and emulsifying/dispersing properties, making it a new and highly effective agrochemical adjuvant.
Product Features
Ultra-Low Surface Tension
Surface tension 19-22 mN/m, with excellent wetting, spreading and penetration
Highly Effective Agrochemical Adjuvant
Can be quickly and easily dissolved or dispersed in water; a new and highly effective agrochemical adjuvant
Enhances Efficacy
Can greatly reduce the surface tension of the solution, reduce the contact angle between droplets and the leaf surface, and enhance the wetting, penetration, adhesion and spreading of the spray solution on plant leaves or pest body surfaces
Eco-Friendly and Water-Saving
Clearly helps improve efficacy, reduce spray volume, reduce the number of sprayings, save water, lower agrochemical pollution and promote environmental protection
Can Replace Imported Products
Performance similar to Dow Corning Q2-5211, can be used as a replacement

Product Applications
This product can be used as a spray modifier, leaf penetration and absorption aid, spreader, etc., and is widely used in herbicides, foliar fertilizers, growth regulators, insecticides and fungicides. It does not decompose the active ingredient and can greatly reduce the surface tension of the solution, reduce the contact angle between droplets and the leaf surface, and enhance the wetting, penetration, adhesion and spreading of the spray solution on plant leaves or pest body surfaces.
Dosage and Usage
Then-and-There Mixing
When used as a tank-mix, the dosage is between 0.02-0.04% (i.e. add 3-6 g of HY-8328 to a 15 kg sprayer)
Agrochemical Formulation
In agrochemical formulations, the dosage is between 0.5-5%
Method of Use
Added directly to agrochemical formulation preparations or used as a tank-mix adjuvant for then-and-there mixing
Precautions
Because the surface tension of organosilicone surfactants is extremely low, protect your eyes when using HY-8328, and strengthen personal protection during spraying operations.
