StatiCon® Glazing

AC-300™ Cast Acrylic for Cleanroom Construction

Description
StatiCon® Glazing is a family of transparent plastic sheet products designed to control static electricity in cleanroom construction applications. AC-300™ Cast Acrylic, a member of this family, is a premium quality cast acrylic sheet which has been coated with SciCron Technologies proprietary, clear, C-300™ static dissipative coating. This unique technology prevents charge generation on the sheet surfaces, thereby controlling particulate attraction and pre-venting 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 uncoated 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 without the need for ionization.
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 conductive discontinuities (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 extruded acrylic. Therefore, extruded material should be specified if a narrow thickness tolerance range is required.

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 thick-nesses, including oversize sheets, available upon request.

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.
For building applications, comply with applicable code regulations.
Clean with soap and water. Do not use abrasives. Avoid inappropriate contact with solvents.
