Abrasion Resistant Plastic
Description
Mar-Con® 600 Acrylic is an advanced technology abrasion resistant highly cross-linked hard coating with excellent abrasion resistance, solvent resistances, and anti-graffiti properties. It is designed for a variety of high performance end uses. Mar-Con 600 hard coating provides enhanced resistance to abrasion of the sheet surfaces from cleaning, handling, and defacement efforts. is combination of properties provides enhanced resistance to hazing, marring, abrasion, and scratching of the sheet surfaces from cleaning, handling, and defacement efforts. Mar-Con® 600 Acrylic plastic substrate is a cell cast acrylic that exhibits excellent optical properties with superior weathering characteristics and solvent welding capabilities. This products can be used in many more applications than would be practical for an uncoated acrylic sheet. Mar-Con 600 can be applied to thin gauge materials without suffering from distortions caused by typical thermal curing processes.
Applications
Mar-Con® 600 Acrylic 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 acrylic sheet surfaces. Mar-Con 600’s hydrophobic surface is resistant to graffiti and can be immediately cleaned if defaced. Typical applications for Mar-Con® 600 Acrylic include applications such as, boxes, displays, display cases, and protective screens. It can also be used for exterior glazing, partitions, enclosures, doors, access panels, and inspection windows when exterior longevity is critical.
Fabrication
Mar-Con® 600 Acrylic is easily fabricated into flat surface configurations using the same equipment and fabrication techniques generally employed with unsurfaced acrylic 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 welding, it is necessary to remove the Mar-Con 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 maintains optimum light transmission without distortion. - Graffiti Resistance
Easy to clean hydrophobic surface. - Superior fabrication characteristics
Results in optimum workability during part fabrication.
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.
Availability
Mar-Con® 600 Acrylic, in cell cast type, is available in clear and a variety of standard transparent colors. White translucent and colored opaque grades are also available. Continuously cast and extruded types are available in some sizes and thicknesses upon request.
Note: Cell cast is a premium form of acrylic plastic but it has a wider thickness variation than other acrylic types. Therefore, continuously cast or extruded material should be specified if a narrow thickness tolerance range is required.
Standard Dimensions (Nominal)
Thickness: 3mm (1/8″), 4.5mm (3/16″), 6mm (1/4″), 9mm (3/8″), 12mm (1/2″) – Note: 9mm and 12mm – cell cast only.
Standard Sheet Size: 48″ x 96″
Other sizes and thicknesses, including oversize sheets, available upon request.
