Rosco RoscoFlamex NF Natural Fiber Flame Retardant treats fabrics made of natural fibers. Among the many fabrics commonly used in scenery or costumes, use Flamex NF on cotton, muslin, scrims, cotton netting, natural velours, wools, linens, natural felts, and most other decorative, garment or upholstery fabrics made with natural fibers. Easy to use, with no greasy after effects, Flamex NF is the best solution for insuring your scenery and props meet local fire regulations.

Using Flamex NF

Rosco Flamex NF has been premixed and does not require any further dilution. The method of application and the amount of Flamex required for sufficient treatment varies with the fabrics in use.

Coverage

One gallon of Flamex NF will treat approximately 500 square feet (46.4 square meters) of fabric.

Applying Flamex

• Dipping: This is the most efficient method of impregnation. Immerse completely for ten minutes, and hang to dry.
• Brushing: Using a wide lay-in brush, brush the Flamex solution into the fibers of the material being treated. Brush in the solution using a criss-crossing pattern to insure adequate absorption.
• Spraying: In a spray application, it is very important that an adequate amount of the Flamex be absorbed. In calculating the amount of solution needed, remember that a substantial portion of the spray will not fall on the fabric. Use a Hudson-type sprayer with a medium nozzle setting. For best results, hang the material to be treated and spray in a back and forth pattern starting at the bottom and working your way up to the top of the fabric sample.

Over saturating the fabric may cause it to stiffen or otherwise alter its hand. ALWAYS treat a test sample to determine how the fabric will react and to test for effective flame retardance.

Certification and Testing

Flamex NF has been approved for use by the California and New York City Fire Marshall and has been tested according to NFPA 701.

Storage

Store Flamex products in non-metallic containers. When metal sprayers are used, they should be thoroughly cleaned immediately after use, including nozzles and accessories. Avoid use of metal buckets or paint containers when possible.
