Abrasion Resistant Plastic
Description
Mar-Con® 600 Polycarbonate is an advanced technology abrasion resistant highly cross-linked hard coating with excellent abrasion resistance, solvent resistance, and anti-graffiti properties. It is designed for a a variety of high performance end uses. This Mar-Con 600 hard coating provides enhanced resistance to abrasion of the sheet surfaces from cleaning, handling, and defacement efforts. Mar-Con® 600 Polycarbonate plastic substrate is a high optic grade polycarbonate that exhibits excellent optical properties with superior impact resistance and flame spread properties. This product can be sued in many more applications would be practical for an uncoated polycarbonate sheet. Mar-Con 600 can also be applied to thin gauge materials without suffering from distortions caused by typical thermal curing processes.
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 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 600 surface helps prevent such damage from short term exposures to these materials. Mar-Con 600’s hydrophobic surface is resistant to graffiti and can be immediately cleaned if defaced. Typical applications for Mar-Con® 600 Polycarbonate include interior and exterior applications such as vertical shatter resistant windows, safety partitions, machine guards, security glazing, enclosures, doors, access panels, display cases, and inspection windows.
Fabrication
Mar-Con® 600 Polycarbonate is easily fabricated into flat surface configurations using the same equipment and fabrication techniques generally employed with uncoated polycarbonate sheet products. For applications requiring heat formed or bent configurations, plastic substrates with SciCron Technologies Forming Grade Mar-Con® 551 coating are recommended. Note: When solvent glue welding, it is necessary to remove the Mar-Con 600 coated surface mechanically to achieve a good bond.
Features and Benefits
- Abrasion resistant, mar resistant, durable surface
The Mar-Con 600 surface is significantly more abrasion resistant 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 abrasion and chemical resistance without changing the appearance of the polycarbonate surfaces. - Graffiti resistance
Easy to clean hydrophobic surface. - Superior impact resistance
Provides exceptional shatter resistance for safety. - Superior flame spread properties
Provides additional protection in a fire.
Cleaning
The Mar-Con 600 surface can be cleaned with a variety of common cleaners (see below 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.
