Mar Resistant Plastic

Description Mar-Con™ Polycarbonate - Forming Grade is a mar resistant plastic sheet product designed for a variety of high performance end uses in which the sheet will be heat formed or bent into soft radius shapes. It is a premium, high optic grade, polycarbonate sheet, surfaced with an advanced technology, clear, durable, cured coating. This coating has excellent resistance to a wide variety of chemicals and solvents and is considerably harder than the polycarbonate plastic substrate. This combination of properties provides enhanced resistance to hazing, marring, abrasion, and scratching of the sheet surfaces from cleaning, handling, or defacement efforts. Mar-Con Polycarbonate - Forming Grade also exhibits excellent impact resistance and flame spread properties. This product can be used in many more applications than would be practical for an uncoated sheet. Applications Mar-Con Polycarbonate - Forming Grade is designed to be used where there is concern about marring of the sur-faces 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 Forming Grade Mar-Con surface helps prevent such damage from short-term exposures to these materials. Mar-Con Polycarbonate - Forming Grade is suitable for use in formed fabricated items, such as; equipment covers, display components, windshields, safety shields, and curved machine guards. Fabrication Mar-Con Polycarbonate - Forming Grade is easily fabricated into flat and bent surface configurations using the same equipment employed with uncoated polycarbonate sheet products. The product is designed to accommodate drape forming and heat bending, however, care must be taken to avoid applying too much heat to prevent damage to the mar resistant coating. Soft radii shapes and bends can be achieved which are smooth, clear, and uniform, if recommended forming techniques are employed. Some distortion and loss of mar resistance in a bend area is nor-mal. On tight bends, particularly in thicker materials, there may be some very fine haze lines in the bend area. When solvent welding, it is necessary to remove the coating mechanically to achieve a good bond. Note: This product is not designed for vacuum formed or drawn configurations.

Features and Benefits Flexible, mar resistant, durable surface The Forming Grade 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. Superior forming and bending properties Results in optimum heat forming during part fabrication. Cleaning The Forming Grade 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.
