Chemical Resistant Laminate techdata

Zhenghang Brand Chemical Resistant Laminate is intended for application to interior horizontal and vertical surfaces where design, appearance, quality, durability, and resistance to relatively harsh acids, alkalis, corrosive salts, and other destructive or staining substances are required. Its application scope covers shelf cabinet, partition board and tabletop used in the laboratories, chemical, medical, scientific, clinics, mortuaries, nursing stations, and other institutional.

Zhenghang provide customers with integrated solutions for interior design. Our professional RD team has been designing a lot of especial color and surface finishing. If normal design not you need, let me know.

The Chemical Resistant Laminate test report of design as NEMA LD3-2005

Cleanability Test/sum of reagents 1-15

Cleaning steps: (see NEMA LD3 2005 for full descriptions)

1. tap water -- removed = (0).

2. BCS + sponge w/1 kg weight -- 25 cycles -- rinse w/ tap water --removed = (1).

3. BCS + baking soda +brush -- 25 cycles -- rinse w/ tap water --removed = (2).

4. cotton ball + nail polish remover -- rub ≤ 2 minutes-- rinse w/ tap water --removed = (3).

5. cotton ball w/ bleach --2 minutes-- rinse w/ tap water --removed = (4).

6. if reagent remains visible = (5).

Cleanability = sum of reagent cleaning scores

Stain Resistance = No Effect / Moderate Effect / Severe Effect -- (reagents with cleaning score=5)

No Effect = no visible color or surface change under the specified viewing conditions

Moderate effect = difficult to perceive stain visible at all viewing angles or directions

Severe Effect = easily perceived stain, or permanent change/damage to the decorative surface

Chemical Resistant Laminate storage and installation

Limitations

Chemical Resistant Laminate is not recommended for application directly to plaster, gypsum board, or concrete. It should not be used in areas where temperatures exceed 275°F (135°C) for prolonged periods of time, or for exterior applications. Do not expose to continuous direct sunlight. Do not chop, slice, pound or hammer on sheet surface.

Storage

Chemical Resistant Laminate should be stored horizontally, back-to-back, face-to-face, with the top sheet turned face down and a caul board placed on top to protect the material from possible damage and reduce the chance of warpage of the top sheets. The material should be protected from light, heat and moisture, and should never be stored in contact with the floor or an outside wall. It is important that the laminate be stored at a temperature not less than 60°F (16°C) and a relative humidity not less than 40%.

Preconditioning

Chemical Resistant Laminates and substrates gain moisture and expand under high relative humidity conditions and lose moisture and shrink under dry relative humidity conditions. Prior to fabrication, allow the laminate and the substrate to acclimate for at least 48 hours at the same ambient conditions. Optimum conditions are approximately 75°F (24°C) and a relative humidity of 45% to 55%. Provisions should be made for the circulation of air around the components. Chemical Resistant Laminate moves about twice as much across the grain as it does in the length direction (sanding direction). Whenever possible, minimize the dimension of the cross grain direction.

Note: Stress cracking can result when high-moisture material is glued to a dry substrate and subsequently exposed to low humidity conditions. Overly dry material, however, may expand and cause bubbling if improperly glued.

Cutting

Chemical Resistant Laminate has a special chemical resistant surface. We recommend the use of sharp, carbide tipped cutting blades with low or negative hook angle profiles. Low feed speeds and high tool speeds are also suggested. A board may be clamped to the saw fence to hold the sheet down and prevent flutter and vibration.

Substrates

Recommended cores are 45# density, industrial grade particleboard (CS 236-66: Type 1, Grade B, Class 2), Medium Density Fiberboard (MDF), or A-C or better plywood. The substrates should be sanded smooth, clean, free of oil or grease, and uniform in thickness. Do not use drywall (gypsum), plaster, concrete, solid lumber, or underlayment.

Adhesives

The strength of the bond between the laminate and the substrate determines the amount of stress that may be transmitted to the substrate. Contact adhesives are the weakest of all recommended adhesives because of their elastomeric nature. PVAc (white glue), urea, and resorcinol adhesives distribute much more of the stress to the substrate, making these assemblies more crack resistant. Follow the adhesive manufacturer’s recommendations.

Assembly

Material, equipment, and workmanship should conform to the industry standard practices, conditions, procedures, and recommendations as specified by ANSI/NEMA LD3-1995, Section 4, Architectural Woodwork Quality Standards, DLPA (Decorative Laminate Products Association) and ANSI 161.2-1979 standards. Panel assemblies should be laminated with a suitable balancing sheet to minimize warpage. Always align sanding marks in the same direction. All inside corners of cutouts must be radiused as large as possible, 1/8" (3.18mm) minimum, to avoid stress cracking. The edges and corners should be smooth and free of chips or nicks.

Chemical Resistant Laminate use and care

Postforming

Chemical resistant laminate sheets can be formed similarly to conventional HPL, but at a lower temperature. Ideal postforming temperature is 250°F (121°C). Tempilaq® (gray colored) can be used to determine the proper temperature. Chemical resistant laminate sheets can be postformed to a minimum 1/2" (12.7mm) outside radius and 3/16" (4.8mm) inside cove radius. Slight color change in the cove is normal, and does not indicate a product defect. Coves should be formed at 300°–325°F (149°–163°C).

Use and Care

Chemical resistant laminate surfaces may be cleaned with a damp cloth and mild detergent. Use of abrasive cleaners, powders, scouring pads, steel wool, sandpaper, etc., will damage the finish and can permanently reduce the stain and chemical resistance of the laminate. Good laboratory practice dictates that all chemical spills should be wiped up promptly. Stubborn stains may be removed by use of organic solvent or hypochlorite bleach, followed by wiping with a soft, damp cloth. If in doubt about the suitability of a particular cleaner or detergent, check with its manufacturer.

Color Matching

Chemical resistant laminate sheets incorporate a special integrated coating which gives the product its chemical resistant properties and a slightly different hue from its corresponding standard High Pressure Laminate (HPL) item. This color difference does not constitute a defect. Review actual chemical resistant laminate sample before specifying. Side-by-side matches between chemical resistant laminate sheet and standard HPL sheet are not recommended, while horizontal/vertical matches are acceptable. Samples are available from Zhenghang.

Chemical and Stain Resistance

The chemicals and reagents listed were placed in contact with the surface of the chemical resistant laminate sheet in a covered method (watch glass cover) for a period of 16 hours prior to visual examination and evaluation. The reagents listed below did not damage the surface of the chemical resistant laminate sheet. Those reagents marked with an asterisk(*) may cause a slight change in gloss or color, depending upon the duration or exposure. Those reagents marked with a double asterisk (**) may cause slight damage, depending upon the duration or exposure. Zhenghang recommends prompt cleanup of all spills, using a damp cloth and mild detergent. If in doubt about the suitability of a particular chemical not listed below, contact Zhenghang at 0086-519-88508107
