  • This single-coated tape only contains a very small trace of outgas.
  • Features excellent sealing properties (sealed level). 
  • Its release liner uses a silicone-free release agent, so the amount of siloxane gas generated is under the measurement limit.
  • There is very little blocking when the tape goes through punching, and it is very processable/workable when cutting off edges etc. 
  • Features excellent repulsion resistance.
  • Does not contain RoHS directive 6 restricted substances.

  • For plugging HDD casing holes


  • Make sure to remove any oils, moisture, dust, etc. from the substrate.
  • As this is a pressure-sensitive adhesive, make sure to apply ample pressure after attachment.
  • Make sure to smooth out uneven or rough surfaces as much as possible.
  • Some materials are difficult to attach to, such as rubber, polypropylene, and polyethylene.  Please check this before use.
  • A minimum temperature of 10℃ is suitable for attachment.  (Initial adhesive strength is reduced at temperatures lower than 10℃ in the winter months, etc.)
  • It takes a little time for the tape's original adhesive strength to take full effect, so avoid placing or using the tape in a situation in which a lot of strength is needed until several hours have passed from the time of attachment.
  • Do not touch the tape with bare hands once removed from the wrapping.
  • When using this product, please avoid contact with materials or tools containing silicone oil, machining oil, or release agents for rolling or metal molds.

[Storage Precautions]

  • Make sure to store this product in a box.
  • Avoid storing in high-temperature or high-moisture areas. This product should be stored in a cool, dark area away from direct sunlight.
  • Please use this tape within 6 months after delivery.

[Safety Precautions]

  • Take a careful consideration if this product is adapted to the use, purpose and condition before using. 
  • The tape may peel in some cases depending on substrate and attachment conditions. 
  • When using this product in areas that may pose a risk of accident, use together with a different joining method.
