Chem+ Chemical Resistant Laminates

PRODUCTS RANGE
DETAILED DESCRIPTION
INFO

Product Description:
Merino Chem+ Lab Grade Laminate is intended for application to Horizontal and vertical surfaces where design, appearance, quality, durability and resistance to relatively strong chemicals like acids, alkalis, corrosive salts and other staining substances are required.

A very special acrylic resin formulation is applied over decorative surface paper to achieve highest degree of chemical resistance together with a maximum scratch resistance. The decorative paper is impregnated with several acrylic coating to make the surface free from any porosity and then hardened by electron beam curing. The impregnated decor paper then is assembled with several layers of phenolic resin treated Kraft paper and pressed under 90Kg/sq cm specific pressure and at about 150°C temperature for about 30 to 40 min.
Advantages:

Chemical Resistant – Merino Chem+ Lab Grade Laminate is resistant to large number of relatively strong chemicals used in a laboratory making it ideal to be used in Chemical, Analytical, micro – biological, healthcare, pharmaceuticals & educational laboratoriesList of Chemicals: Merino Chem+ Lab Grade Laminate is resistant to :

FABRICATION

Merino Chem+ Lab Grade Laminate must be bonded to reliable quality of substrate like Industrial grade particle board, Medium density fibre board or cabinet grade plywood. The substrate should be sanded smooth, clean and free from any oil or grease mark on the surface. This laminate should not be pasted on wall plaster, gypsum board or concrete.

Contact adhesives are recommended to be used for pasting with substrate. PVAC or white glue, urea and resorcinol adhesives are suitable for bonding with this laminate.

When Merino Chem+ Lab Grade Laminate will be pasted on one side of the substrate, Care should be taken to ensure proper balancing of the composite by pasting high pressure balancing or high pressure phenolic laminate known as Backer, on the other side of the substrate.

Care should be taken to ensure an appropriate acclimation balance between the laminate and the substrate prior to fabrication. The decor surface, substrate and backing laminate should be conditioned in the same environment for 48 hrs before fabrication.

Recommended conditioning temp is about 24°C and 50% relative Humidity.

Care & Maintenance

Storage:

Sheets should be stored horizontally with the top sheet turned face down and a thick hard board placed on top to protect the material from possible damage and reduce the chances of getting warped. Stored laminate stock should be rotated such that older sheets will be used first. Laminate sheets should be protected from moisture, and should never be stored where they may come in contact with the floor or outside wall. Always carry the sheets vertically. Never slide the sheet but, lift it while moving it from one place to another. We recommend that ideally two people should carry a full size sheet as carelessness can damage the decorative surface.

Cleaning:
Use a damp cloth or sponge and a mild soap or detergent to clean the surface. Use of abrasive cleaners, powders, scouring pads, steel wool, sandpaper, etc., will damage the finish and can permanently reduce the chemical and stain 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.

Maintenance:

Abrasives: Abrasive pads, scouring powders or cleansers may permanently damage the laminate surface making it susceptible to staining
Hot objects: Even though HPL has high heat resistance, exposure to temperatures greater than 135°C is not recommended. Hence, do not place hot frying pans or dishes directly from the oven or cook top on the laminate surface. As a precaution, protect the surface from heat generating appliances such as pressing irons, toasters, curling irons and electric cookers by using a trivet or insulated pad. Prolonged exposure to temperatures above 65°C may result in separation of the laminate from the substrate
Sharp objects: Never use knives or other sharp objects directly on the decorative surface. Use of chopping block or counter saver is recommended
Impact: Even though High Pressure Decorative Laminates have excellent impact resistance, chipping or cracking may occur. Do not abuse the High Pressure Decorative Laminate by dropping heavy objects such as cans, dinnerware, or glasses or deliberately hammering directly on the surface
