Adhesives Research Showcases Electronically Clean, Ultra Low-Outgassing Adhesive Tapes at DISKCON USA 2003

GLEN ROCK, Pa. (August 8, 2003) - Adhesives Research, Inc., a leading global developer and manufacturer of custom pressure-sensitive adhesive (PSA) tape technology, will be showcasing its latest ARclean® electronically clean PSA technologies for hard disk drive (HDD) assembly at the DISKCON USA 2003 Conference and Exhibition on September 9-10, 2003, in San Jose, Ca. Representatives from Adhesives Research's Electronics Business Unit will be available in booth #202 to discuss these ARclean® products and the Company's capabilities to develop custom PSA products for the HDD industry.

The latest generation of ARclean® products are ultra low-outgassing with improved cleanliness that are available with either permanent or cleanly strippable properties for rework. These electronically clean PSAs are acrylic acid-free with ultra low total VOCs and low extractable ions. Use of these adhesives minimizes HDD system crashes due to contamination while minimizing media fogging and head corrosion. ARclean® cleanly strippable tapes also help to eliminate labor costs and contamination associated with adhesive residue during HDD rework. These electronically clean tapes are available with cleanroom compatible, non-silicone and low extractable silicone polyester release liners.

ARclean® electronically clean tapes are used in various applications in HDD assemblies including bar code, caddy and marketing labels, and bonding and sealing micro-contamination filters. These high-performance PSA tapes can also be used to fabricate the following hermetic seals: warranty, base, perimeter, topcover, screw hole, clockhead, servo track write and seals with adhesive-free zones. ARclean® strippable PSA products are a critical component in HDD assembly, particularly in the fabrication of tape seals and filters where clean strippability from stainless steel, cast aluminum, stamped aluminum or e-coated aluminum is required for rework after the burn-in process.

Current products in the ARclean® line include:
ARclean® 8906, a 4-mil ultra low-outgassing, clear polyester film tape with a permanent adhesive on one side and a cleanly strippable adhesive on the reverse side. This double-sided PSA is suggested for use in fabricating filters and tape seals requiring "adhesive-free zones" where clean strippability off of HDD base plates and covers is required for rework after burn-in.

ARclean® 8971, which incorporates all the properties of ARclean® 8906, but is specifically designed for fabricating environmental seals on HDD assemblies where clean strippability off of HDD e-coated aluminum base plates and covers is required for rework after burn-in.

ARclean® 9019, an electronically clean, ultra low-outgassing adhesive with a 2-mil thermally printable, white polyester film. It is suggested for use in the fabrication of bar code, marketing and caddy labels for hard disk drives.

ARclean® 90124, an easily identifiable, 3-mil black polyester film coated with an ultra low-outgassing adhesive. Supported by a clear polyester non-silicone release liner, ARclean® 90124 is suggested for use in the fabrication of seals for hard disk drive assemblies and components.

ARclean® 8988, an acrylic acid-free, ultra-low outgassing bonding tape with a 2-mil clear polyester film carrier. This permanent bonding tape is suggested for use in the fabrication of tape seals and the bonding of microcontamination filters inside of HDD housings. ARclean® 8988 is heat resistant to the operating temperatures in HDD applications and is protected with a dual non-silicone polyester film release liner system.

Adhesives Research has created a comprehensive global network of sales, R&D and engineering, as well as strategically placed facilities in the United States and Asia that can effectively provide service to the global locations of major HDD OEM design centers and their supply chains. In order to better service one of the largest manufacturing areas for the HDD industry, Adhesives Research recently opened a Technical Center in Singapore that complements the Company's existing sales office. This global network allows the Company to work directly with HDD engineers to understand their specialized adhesive and material challenges when designing the latest disk drives. By providing customers with direct access to its full design resources, Adhesives Research can work closely with HDD OEMs to develop custom products quickly that meet both the customers' specifications and their product commercialization deadlines.

In addition to products for the HDD market, Adhesives Research also offers several categories of specialty PSAs and tape systems to the global electronics market under the ARclad®, ARclear® and Flexshield® brand names. These include:
· High-performance adhesive technologies for wireless communications devices;
· Thermally conductive tapes for thermal management;
· Adhesive-coated foils and metallized fabrics for EMI shielding;
· Electrically conductive tapes for interconnections, static control and grounding.

Available in roll or sheet form, Adhesives Research's PSA systems can be processed by tape converters and fabricators into die-cut components for electronics assembly and industrial applications.

Adhesives Research's pressure-sensitive adhesives are used around the world in the electronics, automotive, construction and display industries, as well as other diverse markets such as medical diagnostics and devices, wound care, pharmaceuticals/transdermals, cosmetics and personal care, and the pulp and paper industries.
