Polyalkyleneoxide Modified Heptamethyltrisiloxane

General Information

  • Product Name: Polyalkyleneoxide Modified Heptamethyltrisiloxane
  • Catalog: SUR-NON-094
  • CAS : 27306-78-1
  • Applications: Enhanced pesticide performance, aqueous formulations, plant growth regulation, others

Introduction

Polyalkyleneoxide modified heptamethyltrisiloxane (PAO-modified HMS) stands as a pivotal advancement in agricultural chemistry, specifically within the realm of silicone adjuvants. This compound integrates the unique properties of heptamethyltrisiloxane with polyalkyleneoxide, forming a synergistic blend that enhances the efficacy of agricultural pesticides.

Characteristics

PAO-modified HMS is characterized by its dual nature:

  • Chemical Composition: It comprises heptamethyltrisiloxane, a silicone-based compound, modified with polyalkyleneoxide chains. This modification imparts both hydrophobic and hydrophilic properties, crucial for improving wetting and dispersion.
  • Surface Activity: At ultra-low concentrations (0.01%), PAO-modified HMS can significantly reduce surface tension, facilitating rapid wetting and uniform dispersion on various agricultural surfaces, including those with high wax content.

Applications

The primary applications of PAO-modified HMS include:

  • Enhanced Pesticide Performance: It optimizes the effectiveness of herbicides, insecticides, and fungicides by improving their coverage and penetration capabilities.
  • Aqueous Formulations: Particularly beneficial for water-based formulations of broadleaf herbicides, where thorough and uniform application is critical for weed control.
  • Plant Growth Regulation: Assists in the even distribution of plant growth regulators, ensuring consistent results across treated crops.

Packaging and Storage

  • Packaging Options: Typically packaged in 25L and 200L drums.
  • Storage Conditions: Stored away from acidic and alkaline substances in cool, dry environments to maintain its chemical integrity and performance over time.

PAO-modified HMS leverages silicone chemistry to enhance the performance of pesticides in modern farming practices. Its unique formulation and versatile applications make it a valuable tool for achieving effective pest management and crop protection strategies.
