Medium-term Retardant Gel FAQ - Frequently Asked Questions
1Product Use
Are Firelce® Medium-term Retardants considered retardants or suppressants?

Firelce® MTR can be utilized as both a suppressant and medium-term retardant. Aerially delivered product in airtankers can be used for direct attack, point protection and indirect or parallel line building. Ground applied product in engines can be used for suppression, mop-up, structure protection, and wet-lining.

How long will Firelce® MTR last once applied?

The duration of Firelce® effectiveness is dependent on weather conditions and viscosity. More viscous Firelce® will last longer than less viscous and is recommended for structure protection. Humidity, temperature, and wind will all affect drying times. In general, Firelce® will last anywhere from 2 hours in the most extreme conditions to 48 hours in cooler, more humid environments.

What are the differences between Firelce® MTR and an elastomer liquid concentrate?

An elastomer is a sticky, glue-like substance designed only for direct suppression, with poor penetration performance. Firelce® MTR allows for free water to penetrate the canopy to the understory and provides excellent wrapping. Though initially easier to mix, Elastomers have very little durability on fire. Testing by independent laboratories has demonstrated that Elastomers and Class A Foam have similar heat resistance abilities, but unlike Class A, the molecular cohesion of the polymer provides very poor penetration - especially in dense canopies. Firelce® MTR is a medium-term retardant with exceptional heat resistance and durability, with effectiveness up to 5,000° F. With available colorants, FireIce® MTRs can be used to apply direct or to build line. Elastomers are made from the same binder chemicals in asphalt, and even small spills can destroy tarmac surfaces, grass, and other terrestrial plants. Elastomers are not compatible with Long Term Retardant, and can cause gumming / clogging issues in aircraft if products are used interchangeably.

What is the difference between Firelce® MTR and other water enhancers / gels?

Firelce® MTR is a highly refined, cross-lined polyacrylate copolymer. GelTech developed a specialized manufacturing process to improve hydration time, consistency, penetration, and adhesion compared to all other gels on the market. Because there is no oil in FireIce® MTR, the product is significantly easier to clean up than other liquid concentrate gels. The copolymer is also significantly more durable than linear polymer gels.

What is the difference between Firelce® MTR and traditional Long Term Retardant (LTR)?

Long Term Retardants are comprised of fertilizers and ammonia and are designed to be most effective at building line (when the water content evaporates). FireIce® MTRs are a force multiplier of water, providing adhesion and durability of the polymer without using harmful ammonia and fertilizers. Direct application of LTR only utilizes properties as a water thickener with limited heat resistance, and it is therefore very expensive per gallon when used in direct applications. LTR is well documented to have toxicity and environmental issues, particularly in aquatic ecosystems, and the fertilizer can promote noxious invasive weed growth during burn recovery. Gum and clay thickened retardants limit penetration in dense canopies. LTR requires expensive infrastructure to mix and load onto airtankers, and salt content requires a significant component of corrosion inhibitors.

What colorants are available?

Firelce® MTR is available uncolored, and in one-part and two-part orange and blue fugitive colorants. The colorants were developed to be timed to the effectiveness of the product.
2Safety & Environmental
Are Firelce® MTR products environmentally safe?

GelTech Solutions® develops and offers only environmentally-safe, non-toxic products that are less corrosive than competitor products. Firelce® MTR products are phosphate and ammonia free and contain no harmful or corrosive chemicals.

Is Firelce® MTR safe for aquatic ecosystems?

Firelce® MTR has been tested by the USFS and is deemed to be non-toxic in aquatic and terrestrial ecosystems. Accidental and intentional water intrusions have had no negative impacts on aquatic ecosystems.

Is Firelce® MTR safe for asphalt tarmacs and pavement?

Elastomer fire chemicals are able to penetrate the surface and destroy asphalt binders, and even small amount can ruin a tarmac or pavement and shut down aviation operations. Unlike elastomer fire chemicals, FireIce MTR is completely safe for tarmacs and pavement, even when spilled accidentally.

What is weight per-mixed-gallon of Firelce® MTR?

Firelce® weighs negligibly more than water; water weighs 8.35 lbs. per gallon, and mixed Firelce® MTR weighs approximately 8.45 lbs. per gallon.

Is Firelce® MTR safer than Long Term Retardant?

Research has shown that Firelce® is environmentally safer than long-term retardant, especially in aquatic ecosystems. Firelce® concentrate is also 90% lighter than long-term retardant. In a DC-10 Very Large Airtanker, that amounts to over 10,000 lbs. in weight reduction.

What happens if residual long-term retardant becomes mixed with Firelce® MTR?

The amount of fire chemical left in airtankers after a drop varies by aircraft, but it is generally a negligible amount. Research has shown there is no noticeable impact on the quality of Firelce® MTR when loaded into an airtanker that previously carried long-term retardant.
3Mixing & Application
How long can Firelce® MTR dry powder concentrates be stored for?

Firelce® MTR dry concentrate buckets have a maintenance-free shelf life of 15 years when stored in a cool, dry area. Liquid gel concentrates often require strict maintenance or shaking procedures at least every 6 months, and may be subject to freezing if left in temperatures below freezing.

How long can batch mixed Firelce® MTR products be stored for?

Once Firelce® is batch mixed, the product can be effective as long as it is maintained at proper viscosity levels. Product should be tested for quality control, as evaporation and UV light exposure may affect viscosity.

Will Firelce® MTR corrode or damage equipment?

No; Firelce® MTR in both powder and mixed gel form is non-corrosive. The product has been tested by Pierce, a premier apparatus manufacturer, and found to be safe for pumps, fittings and other equipment. It has also been tested on plastics, rubbers and many other metals (including UL testing of the Firelce® Fire Extinguisher) and found to be non-corrosive.

Can Firelce® MTR be batch mixed in a baffled tank?

Yes; Firelce® can be mixed in a baffled tank. It is recommended that the discharge and suction ports be plumbed into different baffles for maximum circulation.

Can Firelce® MTR be used with any nozzle?

Yes; when Firelce® powder is batch mixed at the recommended viscosities, it is compatible with all standard fog, straight stream, and adjustable nozzles and most automatic nozzles.

Will Firelce® MTR affect the float gauges in airtankers or engines?

No; Firelce® has been tested on a variety of floats and will not affect their functionality or readings.

Does water quality and temperature affect viscosity and mix ratios?

Yes; water temperature, salinity, pH, chlorine, and mineral content can all slightly affect mix ratios. Unlike Long Term Retardant products, which require exact mix ratios for the corrosion inhibitors to be effective, Firelce® MTR mix ratios are variable and are mixed to finished viscosity, not to a percentage.

Can I use a refractometer for quality control testing?

No; there is no salt content in Firelce® MTR, so refractometers will not show any meaningful readings. Viscosity testing using a marsh funnel is the recommended method for quality control.

FireIce® Polar EcoFoam Class A is designed for a broad range of WUI (Wildland Urban Interface), Wildland and Class A Fire applications, including where cold-water mixing of Class A foam is required.

FireIce® Polar EcoFoam Class A is biodegradable and non-hazardous, and is free of fluorinated surfactants; making Polar EcoFoam safe to use in ecologically sensitive areas, including wilderness areas, vulnerable water sources, and the wildland urban interface.

In low percentage applications (0.1-0.3%), Polar EcoFoam acts like "wet water", breaking the surface tension without excessive foaming, extending the water's ability to wet, penetrate, and absorb heat. On hard-to-wet fuels like peat, duff and vertical surfaces, Polar EcoFoam's adhesion prevents the shedding of water and soaks fuels at a controlled rate.
For higher expansion applications (0.3-1.0%) like aerial delivery or CAFS, FireIce Polar EcoFoam enhances wetting and creates a more durable barrier than plain water. Additionally, Polar EcoFoam raises required fuel ignition temperature, modifies time to ignition, and amends tree stand/fuel complex microclimates by "wrapping" fuel sources in a protective envelope of expanded foam.
