The OCA Adhesive Sheet for iPhone 4 / 4s is a precut transparent optical adhesive sheet designed to make it easier to repair and bond the glass panel to the LCD screen of Apple iPhone 4 and 4s devices. This adhesive does not require curing with a UV lamp, unlike traditional LOCA (liquid optically clear adhesive), which simplifies the installation process and offers a practical, efficient alternative for technicians and users.

Manufactured by Mitsubishi Chemicals, this optical adhesive is recognised for its high quality and transparency, ensuring a firm bond without affecting the screen’s visual quality.

Main features

  • Precut to size: The sheet comes already cut to the exact size of the iPhone 4 and 4s LCD screen, avoiding complicated cutting or adjustments.
  • Easy installation: A simple process that does not require curing with an ultraviolet lamp, saving time and additional equipment.
  • High transparency: Optical adhesive that maintains the clarity and sharpness of the original screen.
  • Compatible with: Apple iPhone 4 and Apple iPhone 4s.

How to use

For the best result, make sure both surfaces to be joined are clean and free from dust or residue. Follow these steps:

  • Remove the large protective film from the OCA sheet.
  • Apply the adhesive side to the new glass panel (not to the LCD screen).
  • Carefully position the sheet in the correct place, as it cannot be repositioned without damage.
  • Press evenly across the entire surface to secure the sheet to the glass.
  • Remove the second protective film and align the sheet with the LCD screen, preferably using a mould to ensure perfect placement.
  • Apply gentle pressure to ensure full adhesion.

Advantages

  • Removes the need for UV curing, making the repair process easier.
  • Reduces the risk of application errors thanks to its precut format.
  • Offers a practical and economical alternative to traditional LOCA Glue.
