GLEN ROCK, Pa.  – Adhesives Research, Inc., a leading independent developer and manufacturer of high-performance pressure-sensitive adhesives (PSAs), tapes, specialty coatings, films and laminates has developed a dual stage adhesive technology that enables alternative design, assembly and manufacturing process options for OLED encapsulation.

The company’s Dual Stage PSA/Ultra Violet (PSA/UV) system is formulated to be cured by UV light to form structural bonds.  Supplied in an easy peel-and-stick coated tape, the first stage demonstrates the instant bonding properties of a pliable PSA. The second stage involves momentary exposure to UV light to quickly form a strong, yet flexible bond to function as a superior barrier to moisture and oxygen – properties important for OLED encapsulation. This technology can also be used to form strong, thin bond lines, while eliminating expensive pre-cure fixturing. Ideally suited for flexible substrates and displays, the PSA/UV technology enables roll-to-roll manufacturing for discrete or multiple part assembly.

Some of the PSA/UV system benefits, which address the challenges manufacturers face when using conventional encapsulation systems, include:

  • Applies as a conventional PSA (from a film or sheet) and cures within few minutes at room temperature.
  • Improved barrier properties after transformation that may eliminate the need for desiccants used with liquid adhesives.
  • Very low shrinkage and low VOC emissions.
  • Consistent thickness with dimensional stability for well-defined bond lines.
  • Bond remains flexible post-cure, eliminating cracks when bent.

PSA/UV also offers several manufacturing efficiencies, such as ease of handling and use, no post-heat program to complete cure or control shrinkage, and the ability to pre-cut parts to shape for a perimeter seal or complete coverage "face" seal.

With more than 500 employees worldwide, Adhesives Research is one of the world’s leading independent developers and manufacturers of high-performance pressure-sensitive adhesives, tapes, specialty coatings, films, and laminates.  Founded in 1961, Adhesives Research offers problem-solving capabilities and custom solutions in adhesive polymerization, mixing, adhesive coating and release liner design supported by extensive product development and analytical support.  The company’s North American and Limerick, Ireland facilities are certified to the updated ISO 9001:2000 standard.                           

 Adhesives Research’s pressure-sensitive adhesives are used around the world in medical diagnostics and devices, wound care, and pharmaceuticals/transdermals, as well as in electronics, displays, wireless telecommunications, window fabrication, and the pulp and paper industry.  Based in Glen Rock, Pennsylvania, Adhesives Research also operates manufacturing facilities in Ireland and Colombia, has sales and marketing offices in Great Britain, Germany, and Singapore, and sales representation in China, Japan, Taiwan, and Thailand.
