Rosco Flamex SF Fibras Sintéticas

Rosco Flamex SF Synthetic Fibers

Synthetic material can be hard to treat since synthetic fibers don't absorb liquids the same way as natural fibers do.

1 gallon (3,8l)

Tax excluded


Flamex SF is comparable to the original Roscoflamex S33. However, do not mix old products with the new Flamex product.. Use Flamex for effective treatment:

  • Nylon
  • Poliester
  • Acrylic
  • Synthetic cotton
  • Rayons

Flamex is designed to be a penetrating treatment that bonds to the surface of the threads deep within the weave of the material, securing the flame retardant chemicals and rendering an effective protective treatment. Flamex SF is a will treat many synthetic fabrics, such as polyesters, nylons, acrylics and rayons, as well as most cotton/synthetic blends. A vast range of synthetic fabrics are used in scenery properties and costumer construction. While Roscoflamex SF will work with many of these, always test a sample to insure compatibility and effectiveness. Leaving no residue or powdery build up, Roscoflamex SF simplifies the task of insuring all your softgoods and scenic fabrics will meet the Fire Marshall's expectations.

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

On average, 46.4 m2 of material per 1 gallon of Flamex (3.8L).


Applying Roscoflamex SF

  • 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.

  • Spray: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
Roscoflamex SF has been approved for use by the California and New York City Fire Marshall and has been tested according to NFPA 701.

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.

Read carefully the instructions supplied with any Flamex product. Rosco offers these products in good faith, but without guarantee of any type, since materials treated and methods of application are beyond the control of the manufacturer. You should determine suitability of the Flamex product for the intended use and always test before using.
