SciCron® AS Acrylic


Antistatic/Dust Shedding - Pastel Compatible

Description
SciCron® AS Acrylic is an antistatic 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 on one side with a cured high performance, permanent, non-contaminating, antistatic coating developed by SciCron Technologies. This proprietary antistatic coating prevents static charge generation on the coated surface, which gives the glazing its dust shedding property. During frame assembly the coated side of the glazing is placed toward the art to prevent dust entrapment in the assembly and to prevent static charge induced damage to charge sensitive art. SciCron AS Acrylic is a superior framing glazing that exhibits excellent optical properties, shatter resistance, mar 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
SciCron AS Acrylic combines several features that make it an excellent premium glazing for framing and display cases. The antistatic coating minimizes static charge generation normally associated with acrylic framing 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. The coating is also mar resistant and chemical resistant which helps protect the glazing surface during the final cleaning of the back side of the glazing prior to frame assembly. SciCron AS Acrylic is also available in a UV light screening conservation grade to prevent UV light induced aging of framed art and documents.

Fabrication
SciCron 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.
  • 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 on the back surface
    Resists damage during pre-assembly cleaning from cleaning solutions that would dull and otherwise harm uncoated plastic.
  • Superior fabrication and solvent welding characteristics
    Cuts and assembles simply without the breakage losses of glass.

Availability
SciCron AS Acrylic is available in standard and UV light filtering conservation grades in both cell cast and extruded acrylic types.

Cleaning Instructions

Antistatic Back Surface


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 follow-ing 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.

Cleaning Instructions

Uncoated Front Surface


Note: Unprotected (uncoated) acrylic surfaces are easily damaged by improper cleaning!

Wash with a dishwashing detergent like Joy®, and clean warm water. Rub with a moistened soft clean cloth. Always rub gently to avoid scratching the surface.

Rinse with clean water before drying with a chamois or cellulose sponge.

Remove grease or oil with hexane, aliphatic naphtha, or kerosene. Always remove residual solvent with soapy water and a final rinse with clean water.

Do not use commercial window cleaning sprays like Windex®, or liquids like acetone, gasoline, toluene, chlorinated solvents, or lacquer thinner.

Never use an abrasive cleaner or scouring pad.

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