- Features and Benefits
- Flexible, abrasion resistant, durable surface - The Forming Grade Mar-Con 551 coated surface, 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.
- Advanced technology, uniform surface treatment - Provides enhanced abrasion and chemical resistance without changing the appearance of the acrylic surfaces.
- Graffiti resistance - Easy to clean hydrophobic surface
- Superior fabrication and bending characteristics - Results in optimum heat forming during part fabrication

- Applications
Mar-Con® 551 Acrylic - Forming Grade is designed to be used where there is concern about 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. The Forming Grade Mar-Con® 551 coated surface helps prevent such damage from short-term exposures to these materials. Typical applications for Mar-Con® 551 Acrylic - Forming Grade include formed fabricated items, such as: equipment covers, display components, safety shields, and curved machine guards.
- Fabrication
Mar-Con® 551 Acrylic - Forming Grade is easily fabricated into a variety of flat and bent surface configurations using the same equipment employed with uncoated acrylic 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 abrasion 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 abrasion resistance in a bend area is normal. 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 Mar-Con 551 coated surface mechanically to achieve a good bond.
- Cleaning
The Forming Grade Mar-Con 551 coated 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.
- Cleaning and Graffiti Removal
Solvents and Cleaning Liquids Found Effective Under Laboratory Conditions
Aqueous solutions of the following can be applied carefully with a soft cloth or sponge for ordinary dirt and grime.Joy® Windex® Formula 409® Sparkle™ Rinse with clean water before drying with a chamois or cellulose sponge.
Never use an abrasive cleaner or scouring pad.
The following solvents, in addition to the above cleaners, can be used to remove graffiti and other stubborn stains.

Packaging & Availability
- Availability
Mar-Con® 551 Acrylic - Forming Grade, 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, extruded types and impact modified types are available in some sizes and thicknesses upon request.
Note: Cell cast is a premium 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 needed.
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 available upon request.
