AC-300 Cast Acrylic for Cleanroom Construction
Description 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.

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.

Light Transmission Spectral Analysis
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.
2. For building applications, comply with applicable code regulations.
3. Clean with soap and water. Do not use abrasives. Avoid inappropriate contact with solvents.
