Product Description

The FR31 fire retardant we carry is highly effective for most fabric, both natural and synthetic. Also effective on cardboard and paper. When testing, the FR31 must be able to penetrate the material it is being applied to. Some synthetic fibres such as nylon for instance, do not allow penetration and the FR31 will bead or sit on top of the fabric. The FR31 would be unable to increase fire retardancy and the nylon would quickly melt or burn. If the FR31 does penetrate the material, then you can do your own burn test by applying a flame. It should be fire resistant and when the flame is removed any burning activity on thematerial should stop immediately.


  • Apply by spraying, padding or immersion
  • Colorless, odorless
  • FR31 does not substantially affect feel or appearance of fabric
  • Water soluble, can be washed out
  • Ready-to-use liquid form
  • Chemically neutral pH 7.0 to 8.0
  • is an aqueous solution of inorganic salts. It is colorless and has a slight odor of ammonia in solution but is odorless when dry
  • is chemically neutral or slightly alkaline with a pH of 7.0 to 8.0. Its primary role is to act as a flame retardant.
  • does not substantially affect the appearance or feel of the fabric if properly applied. The fabric remains soft and pliable. Since FR31 Fire Retardant Fabric Treatment is water soluble it can be washed out of both textiles and materials. Re-treat after laundering.
  • is approved in ready to use, liquid form.


Applications By Industry:

Convention/Hospitality; Furniture; Carpet; Entertainment; Residences; Trade Shows/Exhibitions/Fairs; Senior Citizen Homes; Nursing Homes; Military; Mining; Retail; Pulp and Paper; Libraries; Theaters and Museums; Public Office Buildings; Long Term Care Facilities; Automobile; Recreation Complexes; Publishing; Food Service; Government; Hospitals & Clinics; Hotels & Convention Centers; Rodeo (Straw) and other places of public assembly which are required to be furnished with fire resistant materials to protect the public, as well as property, against accidental ignition or arson.

Applications By Product Group:

Textiles: Lab Coats; Coveralls; Velour; Drapery; Curtains; Carpets; Tents*; Work Clothing; Wall Coverings; Cotton and Canvass; Linen (Table Cloths); Upholstery. Paper and Cellulosics: Trade Show Displays; Straw and Hay; Decorations; Acoustic Tiles; Wood Chips; Sawdust; Packaging; Cardboard; Books and Documents; Crepe Paper; Fiber Roof Board. *The water-soluble properties of FR31 Fabric Treatment limits these applications. Addition of a sealant is required to protect the Fire Retardant from leaching if exposed to water.

Note: FR31 Fire Retardant Fabric Treatment is an aqueous solution of inorganic salts, chemically neutral or slightly alkaline with a pH value of 7.0-8.0. It has very low toxicology, but should be kept out of the reach of children. Read MSDS for detailed precautions.


Hazard Class

FR31 Fire Retardant Fabric Treatment is not subject to WHMIS Regulations, nor is it regulated by Transportation of Dangerous Goods.

  • FR31 Fire Retardant Fabric Treatment can be applied by spraying, coating or immersing a fabric at any point in the manufacturing process.
  • do not dilute or mix with other products.
  • check the fabric for color-fastness before starting the treatment.
  • distribute solution evenly across the entire surface, ensuring that solution does not flow or drip to the extremes whenever possible.
  • dry on a horizontal drying rack, at moderate temperature (between 70° and 175° F) for optimal results.
  • tumble dry fabric in a warm dryer, (maximum temperature should not exceed 175° F).
  • iron fabric using a warm iron (maximum temperature 200° F). Iron a small area first, to ensure the color is not affected.
  • to spray SafeCoat FR31 Fire Retardant Fabric Treatment, use a hand held or back pack pressurized spray container with an atomizer nozzle. Filter the solution into the tank to keep out any solids that may plug the nozzle. With daily use, the sprayer must be flushed out with clean warm water.

Coverage rate:

The required quantity depends on the absorbency of the material, its inherent flammability and its overall weight. As a rough guide: the maximum amount of FR31 Fire Retardant Fabric Treatment required is proportional to the original weight of the material to be treated (80 to 100%). i.e.: if the dry fabric starts out weighing 1 kg, then it should pick up between 0.8 to 1 kg of solution during treatment and retain an additional net added weight of 73 g to 91 g after drying.

Fabric Cleaning and Care Instructions:

Detergents and water or shampooing (i.e.: of drapes, carpets, etc.) will remove FR31 Fire Retardant Fabric Treatment and re-application will be necessary. Re-treat after laundering.
