Cleaning steps: (see NEMA LD3 2005 for full descriptions)
1. tap water -- removed = (0).

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
|
|
0 = removed with water

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
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
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.
