Description of E36

Cryotech E36 Liquid Runway Deicer represents a new generation of deicers. E36 LRD is a potassium acetate-based runway deicer that was approved for use in the U.S. in 1992. Because of its high performance and low environmental effect, the use of E36 has expanded rapidly at airports and military bases. More and more, airport maintenance personnel are called upon to keep runways clean and safe without harming the environment. With legislative and environmental pressures mounting, airports are changing deicing practices. E36 LRD has set the standard for runway deicers for years to come.

For a brief summary of E36's benefits, application information, and product specifications, please see the E36 Fact Sheet.


Advantages of E36

E36 LRD is a high performance, environmentally responsible alternative to glycol and urea based products. Experienced users make the following observations about E36 LRD.

Customer Profile

Potential Customer Profile

Commercial airports and military bases that are concerned with the quality of storm water run-off and require a high performance deicer can benefit from E36 LRD. With increased concerns of deicing chemicals reaching receiving waters, airport managers consider E36 LRD an important tool in managing environmental issues associated with storm water run-off. If storm water drains directly from runways or taxiways into a body of water, NPDES discharge permits require regular monitoring of run-off to determine certain characteristics, including BOD and contaminants. Because of low BOD and high performance, E36 LRD can help acheive storm water run-off objectives. The U.S. EPA recently gave notice to airports to evaluate the use of potassium acetate (E36 LRD) in lieu of ethylene glycol and/or urea. (Federal Register, 09/29/95)


Product Specifications

E36 LRD meets FAA approved specification SAE AMS 1435, "Fluid, Generic, Deicing/Anti-icing, Runways and Taxiways".

See product MSDS for more information.


Product Application Guidelines

Product Application Rates

The amount of E36 LRD to be applied is determined by both the surface temperature and the quality and quantity of ice. Conditions vary, therefore, these application rates are suggested starting points to be adjusted locally as required.


E36 LRD will speed the effect of solid deicers and abrasives. E36 LRD is applied at the spreader outlet, typically for prewetting rates of 5% to 15% by weight of solid material.


E36 LRD is most effective when applied uniformly to pavement surface before freezing precipitation. Prompt mechanical removal of snow and ice is necessary to reduce fluid dilution. Re-application may be necessary if snow and ice begin to bond to the surface.


E36 LRD is an effective deicer when applied in a banded pattern to penetrate to pavement surface and break the bond of ice and snow. The amount of deicer needed varies with temperature and thickness of snow or ice, but should be in the following ranges.

Environmental Impact

Tests with E36 LRD show it readily biodegrades at low temperatures and has a low oxygen demand (BOD) when compared to glycol-based deicers. Toxicity tests rate E36 LRD "relatively harmless" to aquatic life, the most favorable classification used by the environmental community. And the fluid contains neither ammonia nor nitrogen. Therefore, E36 LRD is considered much safer for the environment than either glycol or urea.

As suggested by the FAA, the following general summary of environmental and hazard information is provided. Additional detail is available in the MSDS. Complete test report documentation is available upon request from Cryotech.


The chemical oxygen demand (COD) of E36 LRD was determined using EPA Method 410.1

The biological oxygen demand (BOD) of E36 LRD was determined using the EPA approved dilution method (Hach).


Aquatic Toxicity

Current EPA methods were used for measuring the acute and chronic toxicity of E36 LRD. According to the US Fish and Wildlife scale, material with a LC50 greater than 1000 mg/L is "relatively harmless", which is the least toxic material classification.

Hazard Information


Compatibility With Electrical Components

E36 LRD is an ionized solution and is more conductive than water. Users are advised to take precautions to prevent solutions containing E36 LRD from entering subsurface conduits and electrical components. E36 is compatible with most materials, but exceptions occur such as with galvanized metals. Do not use E36 with galvanized materials.

Equipment Considerations

When selecting equipment to transport, store, and apply potassium acetate runway deicers, the following guidelines should be considered:





Dispensing Equipment


Advisory - Mixing Fluids

Cryotech E36 LRD is certified to comply with SAE AMS 1435. Fluids meeting this specification are unique to each manufacturer and may be adversely affected by mixing with other deicing/anti-icing fluids. Therefore, Cryotech recommends that E36 LRD not be mixed with other manufacturer's products.


Standard Shipments

E36 LRD is shipped to customers in the following units:


Certification To FAA Specifications

The FAA has established standards for liquid runway deicers. At this writing, SAE AMS 1435 covers all liquid deicing/anti-icing compounds including E36. This specification identifies material and environmental properties, and establishes minimum standards for material compatibility and performance. E36 meets or exceeds all requirements of this standard as indicated below. Current certifications are supplied at customer request.
