SURFACE PROTECTION SHEET |
| 摘要 |
This invention provides a surface protection sheet that allows for easy application to an adherend surface with good removability. The surface protection sheet provided by this invention comprises a PSA layer and a support substrate supporting the PSA layer. The surface protection sheet has a peel strength (SA) after adhered to a stainless steel plate and stored at 23° C. for 30 minutes, and a peel strength (SB) after adhered on a stainless steel plate and stored at 70° C. for 168 hours, at a peel strength ratio (SB/SA) of 5 or less. The surface protection sheet has a peel strength to itself of 5 N/25 mm or less when the PSA layer is adhered to itself and peeled apart after one minute. |
