Flame Retardant for scenic properties; availble for Spray, Brush or Immersion.

RoscoFlamex C26

Roscoflamex C26 is a concentrated flame retardant that effectively treats natural-fiber textiles, paper products, and other cellulosic materials.
Roscoflamex has been approved by the New York State Board of Standards and Appeals and has been one of the most widely used flame retardants in the entertainment industry for more than 15 years.

Treating Backdrops:

When treating muslin backdrops, the most efficient method is to treat the fabric prior to painting. This insures that the fiber of the material will readily absorb the Roscoflamex C26. However, many painters prefer to paint their drop first, and flame retard it afterwards, preventing any possible reaction between the Roscoflamex and the painting techniques. In these instances, turn the fabric over and treat the back side of the drop with Roscoflamex C26. Unless the paint treatment is especially heavy, the fibers on the back of a painted drop are usually exposed and will still absorb a sufficient amount of C26. As always, it is important to test the drop to insure that the material has been successfully treated.

Treating Velours:

Velours require careful spraying treatment, and finished drapes should only be attempted after considerable practice on sample material. Compare the weight of an untreated and a dried, treated sample to insure that sufficient Roscoflamex C26 is absorbed.

Hang out the drapes from a counterweighted batten. Work in a back and forth pattern, treating six-foot-high strips in sequence, beginning across the top. Spray the rear side with a fine spray of diluted Roscoflamex C26, making certain no liquid soaks through to the front (pile) side of the fabric. Make one or more uniform spray treatments of the entire drape, until sufficient material is absorbed. It is better to allow for two or more light spray treatments with drying time between than one heavy one.

Caution: Any Roscoflamex C26 treatment falling on the pile surface of velour will affect the appearance and possibly damage the drapery. Do not, in any case, introduce wetting agents or soaps into the Roscoflamex C26 mixture, since they will facilitate movement of the liquid through to the front side of the pile.

Dilution:

Roscoflamex C26 is a concentrated solution that is intended to be diluted with water. To determine the correct dilution for your material, prepare three or four trial solutions between 2:1 and 3:1, water:flamex, using the material you intend to treat. Treat your sample using the same method of application that you will use on the full size material and allow to dry thoroughly. Then test the samples using the methods described on page two, or whatever method is applicable for your local fire regulations.

Application:

Regardless of the method of application, it is necessary to insure that an adequate amount of Roscoflamex C26 is absorbed into the material. This can only be determined by comparing dry weights of untreated and treated material, with the treated material reflecting an increase of 15-20% above the untreated material's weight.

• Dipping: This is the most efficient method of impregnation. Immerse completely for ten minutes, and hang to dry.Dripped Roscoflamex C26 can be re-used if stored in a tightly covered, nonmetallic container. Do not immerse a finished, painted drop.
• Brushing: Using a wide lay-in brush, brush a properly diluted Roscoflamex C26 solution into the fibers of the material being treated. Brush in the solution using a criss-crossing pattern to insure adequate absorption.
• Spraying: In spraying for flame retardance, it is especially important that an adequate quantity of Roscoflamex C26 be absorbed. In calculating the amount of Roscoflamex C26 needed, remember a substantial portion of the spray will not fall on the fabric. Use a Hudson-type sprayer with a medium nozzle setting.

Storage:

Store Roscoflamex C26 only 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.

Coverage:

On average, 300 sq. ft. per gallon of the diluted solution. Coverage is determined by the ease of absorption into the fiber of the fabric.

C26 Quick Tips

1. If you over-saturate a fabric with C26, a greasy build up may occur. To fix this, spray warm water onto the fabric and allow the excess C26 to drip off the material. Several attempts may be necessary to fix the problem. It is then necessary to test the fabric to make sure an adequate amount of Roscoflamex remains.
2. Roscoflamex C26 is mildly corrosive to soft metals. When treating backdrops, avoid getting C26 on brass grommets as they will corrode over time.
3. If you suspect that material you wish to treat with C26 has been starched, launder and dry the fabric first to improve the C26's absorption into the fibre.
4. If undiluted or concentrated C26 spills on the floor, a greasy film can form and be difficult to clean up. Flood the area with large quantities of water to dilute the C26 then mop up.
5. Never use Roscoflamex C26 over metallic paint or oxidation will occur.

RoscoFlamex S33

Roscoflamex S33 effectively flameproofs many synthetic fabrics, such as polyesters, nylons, acrylics and rayons, as well as many cotton/synthetic blends. This ready-to-use liquid is easily applied by immersion, spraying or brushing. Fabrics retain a good soft hand without undue stiffness.

Virtually infinite varieties of synthetic fabrics are available and in wide use in the entertainment industry today. Roscoflamex S33 is an effective treatment for many of these fabrics, but not all. The best method of application on a specific fabric will be determined by a combination of factors including the type of fiber, the weave of the material and the delicacy of the finished fabric. While immersion may be the most efficient way of treating a particularly resistant fiber, such treatment may alter the hand of the material so much as to make it unusable. Always prepare a range of samples to determine the best method for each fabric being used.

Dilution:

Roscoflamex S33 may be used straight out of the bottle. Dilute with water if necessary. This allows the product to be effective on the widest range of materials. Because of the strength of this solution, certain fabrics will develop a white powdery residue after the Roscoflamex S33 has dried. If this occurs on your test sample, dilute the Roscoflamex S33 10% with water and retest. Continue this process until your sample dries with no residue.

Application:

Regardless of the method of application, it is necessary to insure that an adequate amount of Roscoflamex S33 is absorbed into the material. This can only be determined by comparing dry weights of untreated and treated material, with the treated material reflecting an increase of 15-20% above the untreated material's weight.

• Dipping: This is the most efficient method of impregnation. Immerse completely for ten minutes, and hang to dry. Dripped Roscoflamex S33 can be re-used if stored in a tightly covered, nonmetallic container. Do not immerse a finished, painted drop.
• Brushing: Using a wide layin brush, brush a properly diluted Roscoflamex S33 solution into the fibers of the material being treated. Brush the solution in using a criss-crossing pattern to insure adequate absorption.
• Spraying: In spraying for flame retardance, it is especially important that an adequate quantity of Roscoflamex S33 be absorbed. In calculating the amount of Roscoflamex S33 needed, remember a substantial portion of the spray will not fall on the fabric.

Storage:

Store Roscoflamex S33 only 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.

Coverage:

On average, 300 sq. ft. per gallon of undiluted S33. Coverage is determined by the ease of absorption into the fiber of the fabric.

Warning: Use only with adequate ventilation. Do not take internally. Do not store in extreme heat or allow to come in contact with strong acids. Close container after each use. Do not transfer contents to another container. Do not store in metal containers as Roscoflamex may corrode. Wash hands after use. KEEP OUT OF REACH OF CHILDREN.

S33 Quick Tips

1. Certain fabrics are extremely difficult to treat without altering the hand or color of the material. China silk can often be effectively treated with S33 diluted with water 1:2, applied with a sprayer.
2. S33 works by penetrating into the fiber or weave of a synthetic material. Materials like plastic or foams, while synthetic, have no weave to speak of and therefore S-33 cannot treat these types of materials. In this instance it is necessary to apply a flame retardant coating like Foamcoat.
3. Never use Roscoflamex S33 over metallic paint or oxidation will occur.

RoscoFlamex W40

Roscoflamex W40 effectively flameproofs untreated wood, plywood, cellulose board, acoustical board, and corrugated paper. This ready-to-use clear liquid is easily applied by immersion, spraying, or brushing to penetrate the surface of the material without changing its properties. In addition to flameproofing, Roscoflamex W40 also seals and protects the wood that has been treated. Roscoflamex W40 will not change the color of the wood, however, flameproofing may raise the grain slightly. This can be corrected by sanding very lightly.

Roscoflamex W40 is intended for use on untreated wood surfaces. No other coating (paint, clear acrylic, polyurethane, stain, etc.) should be applied on top of Roscoflamex W40. While a paint coating will not diminish the effectiveness of the W40, some paint and coatings may not adhere properly. If the wood is to be painted, test accordingly. Also, some coatings may be flammable when dry. Roscoflamex W40 will only treat the substrate and provides no protection against the possible fire hazard created by a flammable coating applied on top of the treated wood. Consider using Roscoflamex P50 as an additive when painting with Roscopaint. Penetrating stains will not alter the effectiveness of the W40. Do not use water-based clear urethanes or clear acrylics over W40 as clouding may occur.

Dilution:

Roscoflamex W40 is used straight out of the bottle. DO NOT DILUTE.

Application:

• Immersion: This method insures the greatest saturation and is the recommended method for treating wood. Immerse the wood for 2 hours in warm Roscoflamex W40 (100°F) or 8 hours at room temperature.
• Brushing: Brush on three coats of warm W40 to both sides of wood. Apply enough solution to ensure that the material is wet. Allow at least 5 minutes between coats. Clean brushes thoroughly after use.
• Spraying: Spray 3 coats of warm Roscoflamex W40 uniformly to both sides of wood using a Hudson-type sprayer. Allow at least 15 minutes between coats. Clean sprayer thoroughly after use.

Storage:

Store Roscoflamex W40 only 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.

Coverage:

Wood, plywood: 110 sq. ft./gal. in three spray coats. Corrugated paper: 300 sq. ft./gal. Acoustical tile and cellulosic board: 60 sq. ft./gal. in three spray coats.

Warning: Use only with adequate ventilation. Do not take internally. Do not store in extreme heat or allow to come in contact with strong acids. Close container after each use. Do not transfer contents to another container. Do not store in metal containers as Roscoflamex may corrode. Wash hands after use. KEEP OUT OF REACH OF CHILDREN.

W40 Quick Tips

1. W40 is intended as a solution to flame retarding raw wood. Paints and sealers may be applied on top but special considerations must be taken for adequate adhesion over the W40. Also, avoid using water based clear sealers on top of W40 as clouding may occur.
2. Hay can be effectively treated with W40. However, it is necessary to insure that all strands of hay have been treated. As it is often not practical to immerse full bales, it is recommended that bales be separated into smaller sections, immersed and treated individually and then assembled back into bale form.
3. Live trees or plants, especially Christmas trees or wreaths cannot be treated with W40.
