StatiCon AC-300 Cast Acrylic


StatiCon® Glazing
AC-300 Cast Acrylic for Cleanroom  Construction
StatiCon® Glazing is a family of transparent plastic sheet products  designed to control static electricity in clean room construction applications. AC-300 Cast Acrylic, a member of this family, is a premium quality cast  acrylic sheet which has been surfaced with SciCron Technologies’ proprietary,  clear, C-300 static dissipative surfacing. This unique technology prevents  charge generation on the sheet surfaces, thereby controlling particulate  attraction and preventing electrostatic discharge (ESD) events. This performance  is permanent and totally independent of humidity. AC-300 Cast Acrylic offers the cleanroom builder exceptional design versatility since it fabricates  simply with field tools, has fifteen times greater impact resistance than  tempered glass, is less than half the weight of glass for the same thickness  sheet, and is available in large sheet sizes. It also exhibits excellent optical  properties, chemical resistance, surface hardness and mar resistance.Applications
AC-300 Cast Acrylic resists  tribocharging under all circumstances and cannot generate a charge when properly  grounded. This makes it ideal for use in manufacturing and assembly operations  for charge sensitive electronic components where it can help prevent both  immediate and latent ESD caused defects. Since it resists charge build-up it  does not attract contaminants, so it can also help prevent contamination-related  rejects in ultra-clean manufacturing operations. Consequently, it is suitable  for use in cleanrooms for the semiconductor, electronic, micro-manufacturing,  pharmaceutical, and bio-medical industries. Applications include; perimeter  windows, transparent room partitions, light weight floor-to-ceiling window  walls, laminar flow air containment screens, mini-environment glazing panels,  pass-thru modules, equipment enclosures, and desiccator cabinets.Fabrication
AC-300 Cast Acrylic is easily  fabricated into flat surface configurations using the same equipment and  fabrication techniques generally employed with unsurfaced acrylic sheet  products. It should not be used for heat formed bent configurations since the  hard, cured C-300 surface is not designed for heat bending. For more information  on fabrication refer to SciCron Technologies Technical Information Bulletin No.  SP-01.

Features and  Benefits
Cannot be  tribocharged when properly grounded – Prevents build-up of static charge and  accumulation of harmful contamination. Electrostatic decay  in less than 0.05 second per Federal Test Standard 101C, Method 4046.1 –  Results in rapid static dissipation without arcing.Surface resistivity  of 106 – 108 ohms per square – Provides for ESD  control. Permanence in static  dissipation performance – Avoids cost of application of temporary topical  anti-stats. Humidity independent  static charge control – Avoids inconvenience of maintaining high levels of  humidity and damage caused by such humidity. Advanced technology,  uniform surface treatment – Avoids charged “hot spots” often found with  non-uniform temporary topical anti-stats. Superior optical  properties – C-300 surfaced, premium quality cast acrylic means virtually  distortion-free, high clarity glazing. Superior fabrication  characteristics – Superior physical and mechanical properties of cast  acrylic result in simplified fabrication and installation. Inherently  light-weight material with large sheet sizes – Allows much greater design  and installation flexibility than heavy, fragile, conventional glazing. Hard, mar resistant,  durable surface – C-300 surface reduces risk of mechanical surface  damage.Superior chemical  resistance – Reduces risk of solvent or chemical surface damage.Availability
AC-300 Cast Acrylic
is available in  clear and a variety of standard transparent colors including tints which filter  wave-lengths that can interfere with photolithographic operations. It is offered  in cell cast and continuously cast versions.Note: Cell cast  is a premium form of acrylic plastic but it has a wider thickness variation than  continuously cast acrylic. Therefore, continuously cast material should be  specified if a narrow thickness tolerance range is required.
