- Product Description
SAE AMS 1431 Potassium Acetate – Aviation-Grade Runway Deicing Fluid for Critical Winter Operations
SHANXI ZHAOYI CHEMICAL CO., LTD produces SAE AMS 1431 potassium acetate, a professional aviation-grade runway deicing and anti-icing fluid designed for airfield pavement use. Our 27,000-square-meter facility, which was established in 1988, can produce 150,000 tons annually. At temperatures as low as -60°C (-76°F), we provide a transparent, colorless aqueous deicing fluid that can prevent ice adhesion. Our line is certified ISO, KOSHER, and HALAL in accordance with international aviation safety standards. In order to comply with environmental regulations, the formulation maintains its biodegradability while providing low corrosion performance against concrete surfaces, landing gear assemblies, and aluminum alloys.
Key Features & Benefits
Better Performance at Low Temperatures
In extremely cold weather, the fluid remains active and free-flowing, enabling airport operations to continue during the challenging winter months. Stable ice penetration is achieved across a broad temperature range with carefully calibrated concentration.
Non-Corrosive for Aircraft Parts
Unlike chloride-based deicers, this product protects sensitive materials such as cadmium plating, magnesium alloys, and steel-reinforced concrete. It keeps costly infrastructure damage at bay and helps extend the life of aviation equipment.
Sustainable Recipe
Water contamination issues are reduced by the acetate base's biodegradable qualities and low BOD levels. Operators can adhere to stringent environmental regulations without sacrificing the effectiveness of deicing.
Quick Breaking of Ice Bonds
To extract ice from pavement, it swiftly penetrates layers of snow and compacted ice. Faster runway clearance increases flight rotation efficiency and reduces ground handling cycles.

How It Works
The freezing point depression idea is the foundation of SAE AMS 1431 potassium acetate. Water molecules are prevented from crystallizing by acetate ions. After being sprayed on the pavement, the fluid penetrates the ice layers that are already there and stops them from refreezing, which removes the solid relationship between the ice and the concrete.
Potassium ions protect pavement structure while increasing penetration. Because it contains no chloride, it keeps steel rebar inside reinforced concrete from electrochemically corroding.
To facilitate mechanical sweeping, a thin layer of liquid accumulates beneath the ice. Additionally, the residual film provides long-lasting anti-icing protection against fresh frost and snowfall.
Applications
Airport Runways & Taxiways
Suitable for commercial and military airfields that demand rapid pavement clearance, securing safe aircraft movement throughout winter.
Apron & Gate Zones
Ideal for busy aircraft parking areas prone to equipment abrasion risks. It maintains safe working conditions for ground crews during flight turnarounds.
Bridge Deck Treatment
A reliable non-corrosive deicing choice for transport infrastructure, protecting structural steel and expansion joints.
Emergency Cold Weather Response
Can be rapidly deployed during unexpected frost events to quickly restore airfield operation and guarantee continuous flight services.

Manufacturing Process
Our in-house technical team of 60 staff runs continuous production lines, reacting high-purity potassium feedstock with acetic acid materials. Multi-stage purification removes residual chloride and heavy metal impurities.
Corrosion inhibitors are blended under stable temperature to achieve even dispersion inside the solution. Our QC lab carries out real-time monitoring of concentration, pH value and freezing point performance.
Finished liquid goes through fine filtration to meet clarity standards, and automated filling avoids contamination during packaging.

FAQ
Q: What makes SAE AMS 1431 potassium acetate different from regular industrial potassium acetate?
A: The AMS 1431 standard enforces strict corrosion testing, stable freezing point performance and verified compatibility with aviation materials. Ordinary industrial grades do not satisfy these aviation-level validation criteria.
Q: What storage guidelines should be followed during off-season months?
A: Keep containers tightly sealed in temperature-controlled warehouses between 5°C and 30°C. Avoid direct sunlight, and separate storage from strong oxidants and acidic substances.
Q: Is recovered deicing fluid reusable after use?
A: Collected fluid often mixes with pavement debris and meltwater, which weakens deicing capacity. Fresh fluid application is recommended for each operation.
Q: Does this formulation meet environmental disposal standards?
A: Its biodegradable composition can generally be treated via conventional wastewater facilities. Operators need to check local authority limits for discharge and reporting obligations.
Q: What typical dosage should be applied on airport pavement?
A: Dosage varies with temperature, ice thickness and wind conditions. Our technical team can share detailed application recommendations based on your local climate.
