  • About Optically Clear Adhesives (OCA tape)

    An OCA tape consists of highly specialised free-film isotropic adhesives, formulated specifically for transparent applications and to help create high quality, reliable products. The transparent adhesive is engineered to help eliminate common adhesive visual defects such as bubbles, dirt and gels.

    As demand grows for slimmer and sleeker looking electronic devices, OCA tape offers a number of advantages over traditional fixing methods. They provide invisible, light weight and durable adhesion whilst retaining crystal clarity.

    Our transparent tapes, available as a transfer or double coated tape, offer excellent adhesion to various materials, smooth or textured, including glass, polycarbonate, PMMA and PET. Different thicknesses are available for varying gap filling requirements. View our OCA tapes in the products tab above.

    OCA tape characteristics:

    • 99% light transmission
    • < 1% haze level
    • Refractive Index of 1.474 (similar to glass)
    • Birefringence-free, without film carrier
    • High temperature, humidity, and UV resistance
    • Transparent and non-yellowing
    • Precision coating for uniform caliper
    • Resistant to outgassing
    • High cohesive and peel strength
    • Long term durability without delaminating or degrading

    Our applications include:

    • Avionics/military displays.
    • Transparent graphic overlays
    • Optical management films for LCDs
    • Projection screens
    • Bonding film and glass laminates to touch screens e.g. tablets and smart phones
    • Display protection (laminated)
    • Any devices requiring an optically clear bond
