 WILSONART® CHEMSURF CHEMICAL-RESISTANT LAMINATE
Recommended Uses: Wilsonart® Chemsurf® Chemical-Resistant Laminate is produced for work tops and cabinet surfacing in intermediate-type laboratories where weight or cost constraints rule out slate, marble and granite; the possibility of chemical spills rules out conventional high-pressure decorative laminate; or where a trend-aware coloured or patterned surface is desired. Chemsurf is also recommended in areas where indiscriminate use of a variety of cleaning agents may be used. Specific applications include laboratory cabinets, casework, counters and tabletops in hospitals, photographers' darkrooms and product testing facilities. Chemsurf is ideal for nurses' stations, physicians' and dentists' examining and treatment rooms and pathologists' work rooms. It is also practical and attractive surfacing for wainscoting in any of these areas. Stocked in 13 standard colours in Australia / New Zealand.
Manufactured to customer order.
Note: Chemsurf should be protected from damage caused by high heat. If a high-wear surface is needed, Wilsonart High Wear Laminate is recommended. Product Composition: A special resin formulation is applied over a core of kraft papers impregnated with phenolic resin. The decorative face is achieved by layering coloured or patterned alpha cellulose papers between this core and a special face material. These sheets then are bonded at pressures greater than 1000 pounds per square inch at temperatures approaching 300° F (149° C). Finished sheets are trimmed and the backs sanded to facilitate bonding. Basic Limitations Chemsurf Laminates are interior surfacing, not structural materials. They must be bonded to suitable substrates. Do not subject these laminates to extremes in humidity or to temperatures over 275° F (135° C) for sustained periods of time. They should not be exposed to flame, molten metal, metallic sparks or intense, direct sunlight. Nor should they be used as cutting surfaces. Note: Chemsurf Laminate can be damaged by flame from Bunsen Burners. The burners should be placed on a trivet to protect the laminate surface. Patterns & Colours:*
*All Wilsonart Laminate colours and patterns are available with no minimum order quantity. Finishes: #60 Matte (Standard stocked finish ex Australia and New Zealand). A fine matte texture with a slight sheen offers scratch-resistance properties of 2.5 or 3.0 Newtons (measure of force) depending on product type. #90 Crystal (Manufactured to customer order). A fine beaded texture that minimises smudges and finger marks and offers optimum scratch resistance properties of 4.5 Newtons (measure of force) for all product types. Postforming Types

(N) Newtons - measure of force ** For a complete list of acids, bases, solvents, reagents, indicators and other lab materials safe for use on Chemsurf, please see page 6. * Radius listed for face is actually the radius of the form around which the plastic is postformed. The radius listed for back is actually the radius to which the decorative face is postformed. Typical Fire Test Data Test data for Chemsurf Fire-Retardant Laminates are 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 catalogued 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.
General Fire Code Compliance Test data for code compliance result from the UL 723 Tunnel Test method. This procedure has been catalogued 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 These test data are 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 CodesCongress. Used primarily in the South.) UBC Uniform Building Code (International Conference of BuildingOfficials, 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. Codes and Certifications: Chemsurf conforms to typical standards of ANSI/NEMA LD3-1995 for VGP postforming laminate. At present, there is no general industry standard for a high-pressure, chemical-resistant laminate. NOTE: Product types 190 and 690 are not postforming grade laminates. ASTM G-22 Compliance for Product 390 (90 and 60 Finish). Bacterial Resistance Test - No bacterial growth Bacterial Susceptibility Test - No contamination by bacteria growth Staphylococcus aureus, Streptococci faecalis, Escherichia coli, Klebsiella pneumoniae. New York City Material Equipment Acceptance (MEA) number for product type 390 is 262-95-M and product type 690 is 263-95-M. ISO 4586 Standards Various grades of Wilsonart Basic Type Laminates meet or exceed the International Standards Organisation Specifications as found in ISO 4586 titled, "High-pressure Decorative Laminate (HPDL) - Sheets Based on Thermosetting Resins - Part I: Specifications." Chemical and Stain Resistance
Acids Test procedure: Listed materials were placed in contact with Wilsonart® Chemsurf® Chemical-Resistant Laminate surface under 1" (25.4mm) diameter watch cover glass for 16 hours duration prior to evaluation for effect. * Causes slight change of gloss or colour. ** Causes slight damage, with degree of damage proportionate to length of exposure and concentration. Other items leave no effect.
Wilsonart Chemsurf Chemical-Resistant 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. Specialised PVAs, epoxy or contact cement may be used. Take care to ensure an appropriate acclimation 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. Chemsurf sheets should be cut oversize prior to layup, using a carbide-tipped saw as described in American National Standards Institute/National Electrical Manufacturers Association (ANSI/NEMA) LD3-1995. After bonding, laminate should be machined flush on all edges. Postforming Postforming is the preferred edge treatment for counters vulnerable to repeated chemical attack. Chemsurf provides excellent protection and a rounded edge adds safety for users. Chemsurf sheets may be formed successfully with conventional postforming machinery. Optimum bending temperature for outside radius bends is 275° F (135° C). For inside radius or cove bends, maximum recommended temperature is 325° F (163° C). The substrate of a performance laminate should be balanced with a high-pressure phenolic laminate sheet as a backer, to reduce warping and to provide additional protection against chemical attack from condensing fumes and runoff.
