NEW! Introducing Flamex PC for Paper & Cardboard
Flamex PC was formulated specifically to treat the many paper products commonly used in props and scenery construction. Most paper products without a wax coating or other water resistant properties can be effectively treated.
Using Flamex PC
Rosco Flamex PC 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 materials in use. Some discoloration and wrinkling of paper products may occur as the paper materials dry. Multiple light treatments will minimize this.
One gallon of Flamex PC will treat approximately 400 square feet (37 square meters) of fabric.
- Dipping: This is the most efficient method of impregnation. Immerse completely for complete saturation, and hang to dry. Some wrinkling and shrinkage of thin paper products or paper covers may occur
- 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 material. Use a Hudson-type sprayer with a medium nozzle setting. To insure adequate penetration of Flamex allow material to dry after first application, then reapply a second time.
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 PC 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.
