Flame Retardants

Rosco Flamex

Completely reformulated to address this wide range of modern materials and to satisfy the broad spectrum of Fire Marshall regulations, Rosco has introduced six new Flamex products. Similar to the original Rosco Flamex range, each of the six new flame retardants is keyed to a specific family of materials and designed for ease of use and to maximize the effective protective treatment.

Rosco Flamex

These advanced new flame retardant materials have been tested and certified according to the appropriate standards by NFPA, ANSI and ASTM and have certificates of approval from the California Fire Marshall and NYC Fire Department.

Flame Retardants vs Fireproofing

Flame Retardants do not prevent ignition and burning, however successfully treated materials will not sustain a flame on their own. A piece of scenery treated with flame retardant may burn while a source of flame is held in contact with it. However, once the source of flame is removed, properly treated materials will self-extinguish.

Treat & Test

Treated materials should be tested after an 1) initial treatment, 2) after cleaning and 3) periodically as prescribed by the flame retardant manufacturer. To test a material, hold a flame source to the lower edge of a small sample for 10 - 15 seconds, and then remove it. A properly flame retardant material will self-extinguish after a few seconds.

Many flame retardant products are water-soluble and are removed or weakened by laundering and wet conditions. Some are unaffected by dry cleaning, however they should always be retested after cleaning.

Application Methods/ Textiles

Immersion - The most efficient method of impregnating fibers is to immerse unpainted fabric.

Brushing on - Brushing the flame retardant on is less efficient, but generally successful if done thoroughly. It is sometimes necessary to brush on to both sides of the fabric.

Spraying on - Spraying on is also less efficient, but generally successful if done thoroughly and if before and after weighing of the fabric is done to determine that an adequate quantity of the retardant has been absorbed. A substantial portion of sprayed retardant is wasted as it falls to the floor.

Notes:

Application of a flame retardant may alter the characteristics of some fabrics. See the manufacturer's notes for more information. Some fabrics may contain starch added by the manufacturer and will require laundering and drying prior to treatment.

Application Methods/ Hard Scenery

Penetration - Retardant is applied to a material that will allow adequate penetration. This is usually only applicable where immersion is possible.

Coating - Retardant is applied as a protective coating by brush, roller or sprayer. The coating must be complete and meet manufacturers thickness requirements.

Disclaimers

Local regulations regarding fire safety and flame retardants vary widely. You should always check and understand the regulations applicable to your location.

To insure your safety and the successful application of the product, read and follow the manufacturer's instructions.
