3. Product Description

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.

• Type 390 is intended for horizontal, vertical and postforming surfaces and applications, including those where it is necessary or desirable to roll the laminate on a simple radius over the edge of a substrate. This eliminates seams, which are otherwise vulnerable to chemical attack. This type also may be applied to horizontal and vertical surfaces where a functional, durable, decorative material should also be chemical-resistant.

Manufactured to customer order.

• Type 190 is intended for horizontal or vertical non-forming surfaces and applications when a black phenolic core is desirable.
• Type 690 is a good choice for the types of applications listed above, but is recommended where fire codes specify or the environment suggests a fire- and smoke-resistant surface.

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.

5. Installation: Fabrication and Assembly Recommendations

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.

7. Maintenance*

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.

Warning: Prolonged exposure to hypochlorite bleach will cause surface discoloration or a surface more easily stained.
