 WILSONART® FIRE-RATED LAMINATE
Recommended Uses: Fire-Rated Laminate is recommended for interior application where fire codes specify or the environment suggests a fire-resistant and smoke-resistant surface. It may be applied as decorative surfacing for casework and cabinets, wainscoting, interior doors, and wall panel and divider systems. This laminate is particularly appropriate for surfacing furniture in public places such as airports, hotels, office buildings and institutions such as hospitals and schools. Fire-Rated Laminate can offer Class I, II, III, A, B and C fire ratings for almost any interior application.
Product Composition: The decorative surface is composed of melamine resin-treated, alpha cellulose papers. Special kraft core sheets, used to obtain the desired thickness, are impregnated with phenolic resin. Basic Limitations: Wilsonart Laminate is intended for interior use only, and should be protected from continuous exposure to direct sunlight, extremes in humidity and temperatures greater than 275° F (135° C). It is not structural material and must be bonded to a suitable substrate. Wilsonart Laminate should not be used as direct covering for plaster or concrete walls, or for gypsum wallboard. It should not be exposed to flame, molten metal, metallic sparks or intense, direct sunlight. Nor should it be used as cutting surfaces.

Physical Properties of Fire-Rated Laminate
Note: Since Fire-Rated backer sheets are not intended to be exposed to light, wear or everyday use, no physical property tests are in current use. Typical Fire Test Data Test data for Wilsonart Fire-Rated Laminate is obtained by the Steiner Tunnel Test method of the American Society for Testing Materials (ASTM E 84, Standard Test Method For Surface Burning Characteristics of Building Materials). This procedure is cataloged by Underwriters Laboratories, Inc. as UL 723. Typical Flame Spread and Smoke Developed Properties
Note: Adhesive to attain Flame Spread and Smoke Developed figures for bonded laminates (above) is resorcinol. Fire-rated particleboard is Duraflake, with a UL rating of 25/25, or comparable material. The above values are CUL approved. Codes and Certifications: General Fire-Code Compliance Test data for code compliance is from the UL 723 Tunnel Test method. This procedure has been cataloged under the following designations: American Society for Testing Materials ASTM E 84 American National Standards Institute ANSI No. 2.5 National Fire Protection Agency NFPA No. 255 Underwriters Laboratories, Inc. UL No. 723 Uniform Building Code UBC No. 42-1 This test data is the basis for fire codes written by various responsible groups, including: BBC Basic Building Code (Building Officials Conference of America. Used in Midwest and Northeast.) NFPA National Fire Protection Agency (Building Exits Code, Section #101.) SSBC Southern Standards Building Code (Southern Building Codes Congress. Used primarily in the South.) UBC Uniform Building Code (International Conference of Building Officials, or ICBO. Used in far western states.) Many local codes, especially in densely populated areas, have been patterned after these. Examples include the cities of Los Angeles and San Francisco and the Port Authority of New York. General Standards: Fire-Rated Laminate meets the following federal codes: Aircraft Interiors. U.S. Federal Test Method, Federal Aviation Administration, DOT, Part 25.853, Airworthiness Standards: Transport Category Airplane (Interior Finish). Fire-Rated Laminate Types 604, 605 and 607 comply with parts A and C. Military/Ships. U.S. Military Standard MIL-P-17171E (SHIPS) Plastic Laminate and U.S. Military Standard 1623D (SHIPS), "Fire Performance Requirements and Approval Specifications for Interior Finished Materials and Furnishings - Naval Shipboard Use." Fire-Rated Military/Ships
Types 605 and 607 also appear on the U.S. Department of the Navy "Approved Habitability Materials List 9640, SER05M1.11/1148," (Revision J, May 1989), Pages 3 and 4, paragraphs 1.5 and 2(b), for use on bulkhead sheathing, and on NAVSEA Drawing #804-5000991.
Mobile Homes U.S. Federal Register August 9, 1984, Housing and Urban Development Mobile Home Construction and Safety Standard (24CFR), 3280.203. Fire-Rated Laminate Types 604, 605, 607, 264 and 266 comply.
Motor Vehicles/Interiors U.S. Federal Motor Vehicle Safety Standard (FMVSS) 302, "Flammability of Interior Materials." Fire-Rated Laminate Types 604, 605 and 607 comply.
Wilsonart Laminate must be bonded to a substrate of reliable quality and appropriate fire rating, such as particleboard, incombustible cement board or plywood with one A face. Bond with adhesives, and follow the techniques recommended by the adhesive manufacturer. Permanent adhesives are recommended such as specialized PVAs, phenol/resorcinol, resorcinol, and epoxy. Contact cement, such as Wilsonart Adhesives, also may be used.
Take care to ensure an appropriate moisture balance between the laminate and the substrate prior to fabrication. The face and backing laminates and the substrate should be conditioned in the same environment for 48 hours before fabrication.
Recommended conditioning temperature is about 75° F (24° C). Laminates should be conditioned at 45% to 55% relative humidity.
To avoid stress cracking, do not use square-cut inside corners. All inside corners should have a minimum of 1/8" (3.18mm) radius, and all edges should be routed smooth.
Fabricating for Fire Rating Concerns Flame Spread and Smoke Developed data for products fabricated with Wilsonart Fire-Rated Laminate vary with the choice of substrate and adhesive, as well as with pressing conditions. In general, these factors range from most to least fire-retardant, as shown below:
*45 lb. cu. ft. density, industrial grade Methods Assembled pieces should meet ANSI-161.2-1979 specifications. Drill oversized holes for screws or bolts. Screws or bolts should be slightly countersunk into the face side of a laminate-clad substrate.

The decorative surface may be cleaned with warm water and mild soaps, such as those used for hands or dishes. Do not use cleansers that contain abrasives, acids or alkalis; they will damage the decorative surface. Remove stubborn stains with a 1 1/2-minute exposure to hypochlorite bleach such as Clorox®, followed by a clean water rinse.
We recommend that you not allow any of the following reagents to remain in contact with the decorative surface:
If you require a laminate that can withstand these and other chemicals, please refer to the tech data for Wilsonart® Chemsurf® Chemical-Resistant Laminates.
