Adhesives Research (AR), a developer and manufacturer of custom specialty coatings, films, laminates and pressure-sensitive adhesive tapes (PSAs), is to showcase its bonding technologies for the solar cell junction box, encapsulation barrier and bus bar applications for thin film and crystalline photovoltaic (PV) modules at the InterSolar North America exhibition to be held from July 12-14 in San Francisco.
New PSA technologies improve reliability of bonds and capabilities of PV modules. PSA tapes are available in continuous roll formats and are easy to handle. Adhesives Research’s ARclad 92446 and ARclad 92709 PSA technology junction box tapes are designed for applications in Solar Cell Junction Boxes. They feature die-cuttable foam tape technology that allows lamination to the junction box and bonds to the glass directly. It performs better than other similar products in damp heat and accelerated aging tests and adheres well to TPT, metal, glass and fluorocarbon films. The tapes perform well up to temperature of 120°C.
AR's Barrier Adhesives for PV Cells provide strong bonds, and prevent oxygen and moisture formation for effective encapsulation. They are electrically clean, non-corrosive, low-outgassing, environmentally stable, UV-resistant, and have low color and high clarity.
The ARclad 92708 is a pressure-sensitive conductive adhesive. It forms an electrically conductive, stable and cohesive bond, and reduces the micro movement. It can endure high damp heat and thermal cycling conditions. The ARclad 92708 is coated with highly conductive acrylic adhesive.
AR’s ARclad 90038 PSA demonstrates corrosion resistance and outstanding conductivity for bus bar applications. Adhesives Research provides a range of PSA products for electrical interconnections, bonding and assembly, wire management and encapsulation.
