Polyether Modified Trisiloxane C13H34O4Si3agricultural silicone surfactant, super spreading additive

Polyether-modified trisiloxane is a classic agricultural organosilicon super wetting and spreading aid, also widely used in industrial fields as surfactant additive.

### Basic Parameters
- Ion type: Nonionic silicone surfactant
- Density (25℃): 1.01-1.04 g/cm³
- Viscosity (25℃): 20-40 mm²/s
- Flash point: >100℃
- Surface tension (0.1% aqueous solution): 20-23 mN/m
- Turbidity point (0.1% aqueous solution): about 40℃
- Active substance content: ≥98%
- Shelf life: 12 months in original unopened package, stored in cool and ventilated warehouse, avoid high temperature, strong acid and strong base.

### Solubility
Can be dispersed in water; Easily soluble in alcohol solvents such as methanol and isopropanol; Can be mixed with most pesticide technical materials and additives. Note: Siloxane bonds easily hydrolyze and fail under strong acid and strong base conditions.

### Core Applications
1. **Agricultural Crop Protection (Core Use)**
- Bucket mix spray additive: Combined with pesticides, fungicides, herbicides, foliar fertilizers and plant growth regulators, to improve wetting, spreading, penetration and adhesion properties, enhance efficacy, reduce pesticide loss and save pesticide usage.
- Pesticide formulation: Built-in wetting and efficiency-enhancing component for emulsions, suspensions and solubilizers.
- Usage reference: Add 3-5mL solution per 15kg water for standard bucket mixing; conduct phytotoxicity test first for high-temperature and sensitive crops.

2. **Industrial Sector**
- Coatings and inks: Wetting leveling agent to improve wetting of low-energy substrates
- Industrial cleaning: Low-foam wetting and penetrating agent
- Textile additives: Dyeing and bath wetting and penetration additives

### Product Advantages
- Ultra-low surface tension, with super spreading and penetration capability, unmatched by ordinary additives
- Improves leaf adhesion of chemicals, resists rainwater erosion, reduces efficacy loss
- Excellent compatibility, can be used with most agrochemicals and industrial formulations

### Safety Notice
- Avoid contact with strong acid, strong base and high temperature environment, to prevent hydrolysis failure
- Wear protective gloves and goggles during operation
- In case of splashing into eyes or skin, rinse immediately with plenty of clean water
