ACRYLITE® Optical Mar Resistant Technical Information

TECHNICAL INFORMATION ACRYLITE Optical mar resistant Extruded Sheet Product Properties ACRYLITE Optical mar resistant sheet is a continuously manufactured acrylic sheet that has excellent abrasion and chemical resistant properties with outstanding optical quality. It is available with coating on one side MR1 or two sides MR2. While two-side coated sheet provides maximum protection one side coated sheet offers economic advantages for applications where only one side of the sheet is exposed. In addition the uncoated side is ideal for silk screening. ACRYLITE Optical mar resistant sheet provides the following outstanding properties Applications ACRYLITE Optical mar resistant sheet resists marring and scratching from everyday public contact daily cleanings airborne dirt and dust that are found in many applications. This property significantly extends the service life of the product. Although the coating provides an extremely hard surface to resist these abuses it is not resistant to intentional gouging with sharp-tipped objects such as knives or screwdrivers. ACRYLITE Optical mar resistant sheet is ideal for a wide variety of applications including Glazing P-O-P Displays Store Fixtures Menu Boards Electronic Displays Museum Displays Signs Directories Furniture Interiors Framing Sports Arena Glazing Architectural Glazing Security Glazing Automotive Interiors Instrument Cluster Panels ACRYLITE Optical mar resistant 1970D Technical Information 1124 Optical clarity Abrasion resistance Chemical resistance Ease of fabrication Light weight half the weight of glass Strength many times the impact strength of glass Because ACRYLITE Optical mar resistant sheet offers protection from chemical attack many household glass cleaners can be used on the coated surfaces. Recommended cleaning agents and chemical resistance information can be found on page 4. ACRYLITE Optical mar resistant Extruded Sheet Product Specifications Color Color Number 0A000 MR1 0A000 M

Resistance to wear is measured by exposing a sample to continuous contact with an abrasive wheel in the Taber Abrasion Test. Weathering The following graph shows typical test data demonstrating the outstanding properties that ACRYLITE Optical mar resistant sheet offers versus conventional uncoated acrylic. ACRYLITE Optical mar resistant sheet is primarily intended for indoor applications such as picture framing P-O-P displays store fixtures menu boards etc. Use in outdoor applications is typically limited to three years of exposure.

icals versus uncoated sheet. ACRYLITE Optical mar resistant sheet can be stored saw cut drilled routed milled and laser cut using the same tooling and techniques that are used when machining ACRYLITE sheet. Please refer to ACRYLITE sheet Technical Briefs on www.acrylite.co for details on how to perform certain machining steps or to find manufacturers of equipment and tooling. When performing any type of machining operation to ACRYLITE Optical mar resistant sheet it is recommended to leave the protective masking on the sheet. Note some chemicals will attack edges and uncoated surfaces of the sheet.

ACRYLITE Optical mar resistant 1970D Technical Information 1124 There are certain operations that are not recommended for ACRYLITE Optical mar resistant sheet. They may damage or in some manner adversely affect the performance of the abrasion resistant coating. The following operations have fabrication restrictions Edge Preparation Scraping wet sanding and buffing are acceptable methods of preparing a finished edge. Flame polishing is not recommended. Overspray from the flame will cause the surface coating to crack or craze. This may lead to delamination of the coating and a loss of abrasion resistance in the affected area. Cementing ACRYLITE Optical mar resistant sheet is available with t

he abrasion resistant coating on one or two sides. When cementing to a non-coated surface use the same solvent or polymerizable cements commonly used on ACRYLITE sheet. Solvent cementing to an abrasion resistant coated side requires surface preparation. To solvent cement to the coated side the coating must first be removed by wet sanding or routing. When removing the coating ensure that the bonding surface is flat clean and free of stress. Annealing the piece will ensure a stress free surface. Refer to the Cementing Technical Brief for details procedures and a list of acceptable cements on www.acrylite.co. Thermoforming Line bending or thermoforming ACRYLITE Optical mar resistant sheet is not recommended. Due to differences in the thermal properties of the coating and substrate these heating processes can lead to delamination of the coating. Page 35 ACRYLITE Optical mar resistant Extruded Sheet Painting Silkscreening The abrasion resistant coating provides chemical resistance which will prevent some inks or paints from adhering properly. NOTE the uncoated side of the one-side coated product is ideal for these applications. Contact our Resource Center for more information. Cleaning A liquid detergent and water solution is the recommended cleaner for ACRYLITE Optical mar resistant sheet. While the use of abrasive cleaners is not recommended the following brand name cleaners have been tested and found to work well on coated surfaces. Fantastik household cleaner Mr. Clean household cleaner Formula 409 household cleaner Top Job household cleaner Glass Plus cleaner Windex window cleaner Graffiti Removal Several solvents and cleaning agents are effective in graffiti removal. Although ACRYLITE Optical mar resistant abrasion resistant sheet has excellent chemical resistance cleaners and solvents should be tested before using to ensure that they do not harm the coating. Avoid exposure of edges and uncoated sheet surface to cleaning agents. For additional information vi

sit our Resource Center at www.acrylite.co. ACRYLITE Optical mar resistant 1970D Technical Information 1124 Recommended Cleaners Due to the varying nature of graffiti some cleaning agents will be more effective at removal than others. The cleaning agent below has been found to work well on a variety of graffiti. Be sure to read the suppliers SDS and follow their directions carefully for handling use and disposal of the cleaner. Commercial Remover GRAFFITI TERMINATOR REMOVER West Coast Chemical Corp 800-223-0526. Procedure Apply the cleaner generously avoiding contact with uncoated surfaces. Allow the cleaner to penetrate the graffiti for 2 5 minutes. Remove the graffiti by rubbing with a soft cloth. Repeat these steps as needed to remove the graffiti. A plastic putty knife or smoother blade found in the wallpaper section of a home improvement store may be used to scrape at stubborn or hardened paints but care must be taken not to gouge the coating. Never use a razor blade metal knife or scraper. Wash the area with mild soap and water to remove residue. Code Approval ACRYLITE Optical mar resistant sheet meets the requirements of the following codes and regulations ANSI Z 97.1 for Safety Glazing Materials Used in Buildings ANSI Z26.1 AS-4 5 6 7 for Safety Glazing Materials for Glazing Motor Vehicles Uniform Building Codes for use as a Light Page 45 ACRYLITE Optical mar resistant Extruded Sheet POLYVANTIS Sanford LLC 1796 Main Street Sanford ME 04073 USA www.polyvantis.com www.acrylite.co Semi-finished polymethyl methacrylate PMMA products from POLYVANTIS are sold on the European Asian African and Australian continents under the registered trademark PLEXIGLAS in the Americas under the registered trademark ACRYLITE both owned by Rhm GmbH Darmstadt or its affiliates. Fire Precautions ACRYLITE sheet is a combustible thermoplastic. Precautions should be taken to protect this material from flames and high heat sources. ACRYLITE sheet usually burns rapidly to comple

tion if not extinguished. The products of combustion if sufficient air is present are carbon dioxide and water. However in many fires sufficient air will not be available and toxic carbon monoxide will be formed as it will when other common combustible materials are burned. We urge good judgement in the use of this versatile material and recommend that building codes be followed carefully to assure it is used properly. Compatibility Like other plastic materials ACRYLITE sheet is subject to crazing cracking or discoloration if brought into contact with incompatible materials. These materials may include cleaners polishes adhesives sealants gasketing or packaging materials cutting emulsions etc. See the Tech Briefs in this series for more information or contact your ACRYLITE sheet Distributor for information on a specific product.
