Removable protective film LIOELM™ LE501

Removable protective film LIOELM™ LE501
It is a protective film "LIOELM ™ LE501" that uses a special polyurethane pressure sensitive adhesives and has excellent reworkability and air loss resistance. It is made of highly transparent PET, so it has excellent transparency. It can be used as a substitute for silicone-based protective films, such as surface protection and process protection for touch panel products.

Features

Excellent Bonding Performance

Specially designed urethane pressure sensitive adhesives achieves bonding performance equivalent to silicone pressure sensitive adhesives.

貼り合わせ性能試験

* The center of the sample is placed in close contact with the glass plate, and the time it takes for the tape to adhere under its own weight is measured.
Compared to conventional products, the LIOELM ™ LE501 has excellent pressure sensitive adhesives wettability, adheres in a short time, and exhibits excellent air loss.

Notes in Use

  1. Clean the adherend (Remove dust, any other foreign particles, water, and oil.)
  2. Make sure that the adherend is free of burrs and warpage.
  3. Apply the tape to the adherend at a temperature of around 20 degrees centigrade wherever possible.
  4. After applying the tape, press firmly.
  5. Be sure to conduct a test before using the tape to check that the tape is suited for the application.
  • These tapes are for industrial use only. Do not use them for the following applications.
    ・Applications that involve or may involve the direct attachment of the tape to the skin.
    ・Applications that involve the direct attachment of the tape to food.

Notes on strage

  1. Store the product in a room away from sunlight. Keep it away from high temperatures and humidity. (The desirable temperature is 5 to 40 degrees centigrade, and the desirable humidity is 60% or lower.)
  2. Avoid placing the product directly on the ground or floor. Place it on a table that allows air to pass through.
  3. When storing tapes in a stack, be sure to insert a removable material, such as inserting paper, between the tapes and stack them vertically.
