Roscoflamex PA | Paint Additive

Roscoflamex PA is a clear, un-pigmented additive designed to create a flame retardant paint layer. Simply add one full jar of Roscoflamex PA to a US gallon (3.79L) of water-based paint to achieve a flame retardant coating. This additive is compatible with most latex or vinyl acrylic paints—though it should always be tested with your specific paint choice—and should not be used with metallic paints as metal pigments may react, tarnish, or corrode. Note that Roscoflamex PA does not alter the flammability of the substrate being painted; it only provides a retardant treatment that slows the spread of fire along the surface.

Using Roscoflamex PA

Roscoflamex PA comes pre-measured and is intended for use with a single US gallon (3.79L) of paint. Once combined, the paint/Flamex mixture can be diluted as desired, but the resulting dry paint film must be no less than 4 mils in thickness. The fire retardant effectiveness depends on both the additive and the coating thickness. Roscoflamex PA is not a substitute for other Roscoflamex products; where possible, the appropriate Roscoflamex product should be applied to the substrate material.

Note: When using Roscoflamex PA in Rosco Supersaturated paint, add one 8 oz. jar to one quart of undiluted Supersaturated paint, then dilute this mixture at least 1:1 with water. Mix thoroughly before use.

Coverage

8 oz. of Roscoflamex PA mixed into one gallon of paint will treat approximately 300 square feet (28 square meters) of material, according to the paint manufacturer's guidelines.

Applying Roscoflamex PA

Apply the treated paint using a brush, roller, or sprayer as per the paint manufacturer's instructions. Regardless of the method, it is vital that a complete paint film is formed and that the dry film thickness of the finished coating is not less than 4 mils. Incomplete or too-thin paint films will not provide an effective barrier against the spread of fire.

Certification and Testing

Roscoflamex PA has been approved for use by the California Fire Marshall and has been tested according to ASTM E84 Class A.

Storage

Store Flamex products in non-metallic containers. When using metal sprayers, clean them thoroughly immediately after use—including nozzles and accessories. Avoid using metal buckets or paint containers whenever possible.

Rosco offers these products in good faith, but without guarantee of any type, as the materials treated and methods of application are beyond the manufacturer's control. Always determine the suitability of the Flamex product for your intended use and test before full-scale application.
