MATERIALS: Adhesives Research’s ARclear® 92400 and ARclear® 92469 are new optically clear, electronically clean, pressure-sensitive adhesive (PSA) tapes for bonding surfaces in capacitative touch screen assemblies. They provide reliable optical bonds across the entire glass viewing surface of capacitative touch screens to indium tin oxide (ITO)-coated substrates. Both tapes feature the company’s new AS-192 adhesive that demonstrates low extractable anions and low outgassing of volatile organic compounds (VOCs) while retaining optical transparency and clarity. The adhesive is acid-free and does not contribute to corrosion of the ITO layers to assure long-term stability of the finished product. ARclear® 92400 is a 1 mil transfer adhesive and ARclear® 92469 is a 2 mil transfer adhesive. Both feature an optically clear polyester release liner on each side of the adhesive for ease of handling and application. The company can customize a tape product to a customer’s unique specifications utilizing the AS-192 adhesive with adhesive thicknesses up to 3 mils in transfer adhesive and double-sided constructions.
