Unlike most flame retardants that merely delay the amount of time before something catches on fire, PYROCHILL is a fire inhibitor product.  PYROCHILL prevents any treated material from combusting into flames.

When PYROCHILL is present, it can act in three key ways to prevent fire ignition. 

1.) PYROCHILL disrupts the combustion stage of a fire cycle, including the prevention of “flash-over,” or the burst of flames that engulfs a room and makes it much more difficult if not impossible to escape.

2.) PYROCHILL limits the process of decomposition by physically encapsulating the available fuel sources from the material source with a fire-resisting “char” layer.

3.) PYROCHILL dilutes the flammable gases and oxygen concentrations in the flame formation zone by emitting nanoparticles of water, nitrogen and other inert gases when it encounters heat or flame.



When mixed and applied as directed, PYROCHILL may be used to treat any porous outdoor vegetation or building materials.


  • In the prevention of wildfire, PYROCHILL is ideal to treat dry or semi-dry vegetation inclusive of dead or fallen trees, scrub brush, dried pine needles, leaves, bushes, etc. PYOCHILL also prevents live trees from combusting into flames, e.g. Pine, Redwood, Sequoia, Elm, Alder, Oak, Walnut, Fern. 

  • The flameproofing of log cabins, barns, sheds, canvas awnings, outdoor decking, cabanas, barbeque areas, and fencing.

  • The treating of indoor carpet, upholstery, curtains, fabric blinds, wooden cabinets, clothing, and camping gear.

  • The treating of automobile upholstery and carpeting, buses, RV’s, campers, boats, and airplanes.

Class A

Class A fires are defined as ordinary combustibles. These types of fires use commonly flammable material as their fuel source. Wood, fabric, paper, trash, and plastics are common sources of Class A fires. This is essentially the common accidental fire encountered across several different industries. Trash fires are one such example. 

Class B

The Class B fire is defined as one that uses a flammable liquid or gas as its fuel base. Common liquid based fuel sources include petroleum based oils and paints, kerosene, and gasoline. Flammable gases such as butane or propane are also common fuel sources in Class B fires. Class B fires are a common hazard in industries dealing with fuels, lubricants, and certain types of paint. Smothering these types of fires to remove oxygen is a common solution as are chemical reactions that produce similar effects. Note that cooking fires have their own classification and are defined as Class K fires.


Class C

The Class C fire is defined as a fire that uses electrical components and/or energized equipment as its fuel source. Electrical fires are often fueled by motors, appliances, and electronic transformers. Electrical fires are common in industries that deal with energy or make use of heavy electrically-powered equipment. However, electrical fires can occur on smaller scales in all businesses (i.e. an overloaded surge protector or bad wiring) and should be taken seriously. To extinguish such fires you must first cut the power off and then extinguish the fire.

Class D

The Class D fire is defined as one that uses a combustible metal as its fuel source. Examples of such combustible metals include titanium, magnesium, aluminum, and potassium. Note that there are also other metals with combustive properties you may encounter. Class D fires are a danger in laboratory environments. However, be aware that combustible metals are used as part of production and other industry processes, and you need to be certain of what materials you are using for day-to-day operations. When confronted with such a fire, common extinguishing agents such as water are ineffective and can be hazardous. 

Class K

A Class K fire is defined as a cooking fire involving combustion from liquids used in food preparation. Technically a type of liquid fire, Class K fires are distinct enough to warrant their own classification. Cooking fires are fueled by a wide range of liquid cooking materials. Greases, cooking oils, vegetable fat, and animal fat are all fuel sources found in Class K fires. Class K fires are naturally of concern in the food service and restaurant industry.



PYROCHILL FIRE INHIBITOR and EXTINGUISHER is compliant with the following tests and certifications:

  • ASTM E84/UL723 flame spread and smoke development on Wood

  • ASTM D64 13-15 Vertical Flame Resistance

  • NFPA 701 for flame propagation of textiles

  • NFPA 705 Field Flame Test

  • NFPA 260 Cigarette Ignition

  • CAN/ ULC-S109 Large Flame and Small Flame

  • CCR Title 19, Sec. 1237.1 Flame Resistance

  • CE Certified

Meets the certification standards of the U.S. Forest Service which tests for corrosion properties along with environmental, safety and health testing. These tests ensure that the product is safe for the personnel who use it and safe for the environment. The U.S. Forest Service tests also ensure that the product will not deteriorate equipment, apparatus, or aircraft used to mix or apply the product.

Note:  PYROCHILL is specifically formulated to make water more effective. The unique combination of PYROCHILL and water significantly reduces water's surface tension, when mixed with the surrounding environment by creating a barrier between the fuel and the fire, granting firefighters the capability to fight fire more effectively absent of residual effects.  

This piece of PYROCHILL treated carbon fiber has a combustion temperature of 390 degrees and the hand held torch is emiting 2600 degrees farenheit.
