Mar Resistant Plastic

Description Mar-Con™ Polycarbonate is a mar resistant plastic sheet product designed for a variety of high performance end uses. It is a premium quality polycarbonate sheet which has been surfaced with an advanced technology, clear, hard, durable, cured coating. This coating has excellent resistance to a wide variety of chemicals and solvents and is considerably harder than the soft polycarbonate plastic substrate. This combination of properties provides enhanced resistance to hazing, marring, abrasion, and scratching of the sheet surfaces from cleaning, handling, and defacement efforts. The plastic substrate is a high optic grade polycarbonate sheet so Mar-Con Polycarbonate also exhibits excellent optical properties. In addition, it has superior impact resistance and flame spread properties. Consequently, this product can be used in many more applications than would be practical for an uncoated polycarbonate sheet. Applications Mar-Con Polycarbonate is designed to be used where there is concern about scratching and abrasion of the surfaces of the plastic sheet from handling and other moderate abuse. It is also designed for applications requiring improved splash and wipe down resistance to many common chemicals and solvents which would normally damage the polycarbonate sheet surfaces. The Mar-Con surface helps prevent such damage from short term exposures to these materials. Mar-Con Polycarbonate is suitable for use in fabricated items, such as, boxes, displays, and display cases. It can also be used for machine guards, safety and security glazing, partitions, enclosures, doors, access panels and inspection windows. Fabrication Mar-Con Polycarbonate is easily fabricated into flat surface configurations using the same equipment and fabrication techniques generally employed with unsurfaced polycarbonate sheet products. It should not be used for heat formed bent configurations since the hard, cured Mar-Con mar resistant surface is not designed for heat bending. Note: When solvent welding, it is necessary to remove the Mar-Con surface mechanically to achieve a good bond.

Features and Benefits Hard, mar resistant, durable surface The Mar-Con surface, harder than the base plastic, reduces risk of damage to the sheet surfaces from frequent cleaning and handling. Superior chemical and solvent resistance Reduces risk of solvent or chemical damage to the sheet surfaces. Excellent optical properties High clarity, high gloss coating on a high optic substrate maintains optimum light transmission without distortion. Advanced technology, uniform surface treatment Provides enhanced mar and chemical resistance without changing the appearance of the polycarbonate surfaces. Superior impact resistance Provides exceptional shatter resistance for safety. Superior flame spread properties Provides additional protection in a fire. Cleaning The Mar-Con surface can be cleaned with a variety of common cleaners (see reverse side for specific recommendations). Care should be taken to avoid the use of any cleaner or cleaning solution which contains an abrasive. In addition, all wipes, sponges and drying towels should be clean and free of any grit which could damage the surface. Availability Mar-Con Polycarbonate is available in clear, black opaque, and transparent gray and bronze tints. Other colors may be available upon special request.
