Mar Resistant/Antistatic Dual-Coat™ - Pastel Compatible
Description
Mar-Con® AS Acrylic is a mar resistant/antistatic Dual -Coat™ glazing for framing art, memorabilia, photographs, and documents, and for fabrication of shadow box assemblies, museum cases and displays. It is a premium optical quality acrylic sheet coated with two cured high performance, permanent, non-contaminating coatings developed by SciCron Technologies. The front side is coated with Mar-Con® mar resistant coating, and the back side with an antistatic coating. This combination yields a glazing product with excellent resistance to marring and scratching on the front side and virtually no static charge generation on the back side. Mar-Con AS Acrylic is a superior framing glazing that exhibits excellent optical properties, shatter resistance, and chemical resistance. It fabricates simply, weighs less than half the weight of glass of the same thickness, and is available in large sheet sizes.
Framing and Display Case Applications
Mar-Con AS Acrylic combines several features that make it an ideal premium glazing for framing and display cases. On the front side, the hard Mar-Con coating helps prevent damage from cleaning and moderate handling abuse. This chemically resistant surface also helps protect the plastic from cleaning solutions and repeated wipe downs, thereby extending the useful life of the glazing. On the back side, the antistatic coating minimizes static charge generation normally associated with acrylic glazing. This prevents static charge induced damage to framed documents and fine art by preventing charge generated attraction of pigments and inks from art surfaces. This can be particularly important when framing printed documents, pastels, chalk art and charcoal art. In addition, the antistatic surface greatly simplifies frame assembly by preventing static charge attraction of particulates to the back side of the glazing. Charge attraction of contaminating particulates from the air is a well-known framing bottleneck, particularly in low humidity environments. A UV light screening conservation grade Mar-Con AS Acrylic is also available to prevent UV light induced aging of framed art and documents.
Fabrication
Mar-Con AS Acrylic is easily fabricated using the same equipment and fabrication techniques generally employed with uncoated acrylic sheet products. Fabrication procedures should be carried out with the protective masking left on the sheet surfaces to minimize the possibility of damage. Use of inappropriate equipment and tools, not designed for plastic fabrication, can result in melting, cracking, or shattering of the plastic substrate during cutting and fabrication procedures. This can damage the plastic permanently and could result in serious injury to equipment operators. Always observe appropriate safety precautions when fabricating SciCron Technologies products. Contact SciCron Technologies or your distributor for information about appropriate equipment and fabrication procedures.

Features and Benefits
- Effective antistatic hard coat type back surface
Prevents attraction of particulates during and after frame assembly, while reducing the chance of marring or scratching during fabrication and assembly.
- Humidity independent static charge control
Prevents static charge induced damage to printed materials and fine art even in very low humidity conditions.
- Hard, mar resistant, durable front surface
Reduces risk of damage to the glazing surface from cleaning and handling.
- Premium optical quality acrylic sheet
Minimizes distortion, allowing art to be viewed naturally.
- Inherently lightweight, shatter-resistant plastic in large sheet sizes
More versatile, safer, and easier to handle than heavy, fragile glass.
- Excellent chemical resistance
Resists damage from cleaning solutions and solvents, which would dull and otherwise harm uncoated plastic.
- Superior fabrication and solvent welding characteristics
Cuts and assembles simply without the breakage losses of glass.
Availability
Mar-Con AS Acrylic is available in standard and UV light filtering conservation grades in both cell cast and extruded acrylic types.

Cleaning Instructions Front and Back Surfaces
The following solvents and cleaning liquids were found to be effective under laboratory conditions.
For ordinary dirt and grime, aqueous solutions of Joy® or Formula 409®, or spray-on commercial window cleaners like Windex® and Fantastic®, can be applied carefully with a soft cloth or sponge.
Rinse with clean water before drying with a chamois or cellulose sponge.
For stubborn stains it is possible to use one of the following solvents applied carefully with a soft cloth or sponge:
isopropyl alcohol, methanol, hexane, aliphatic naphtha, kerosene, or butyl cellosolve (for paints, inks, etc.)
Always remove residual solvent with soapy water and a final rinse with clean water.
Never use an abrasive cleaner or scouring pad.

Precautions:
- Acrylic plastic is a combustible thermoplastic. Avoid exposure to flame and excessive heat. Observe fire precautions appropriate for comparable forms of wood and paper.
