Precautions

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.
