Notes：
1.Release Strength
10 to 20 gf/inch, all the data mentioned above are test by our company, There are many test methods on the market.
For the test methods on the market, we have the following reference values for reference:
- Use TESA 7475 adhesive tape laminated for 30 minutes at room temperature, result: 8 to 13gf/inch
- Use TESA 7475 adhesive tape laminated for 24 hours at room temperature, result: 15±3gf/inch
- Use TESA 7475 adhesive tape laminated for 24 hours at 70℃, result: 22±5gf/inch
2.Residual Viscosity Rate
The Residual Viscosity Rate test methods on the market are mostly same presently, but the difference in the method affects the test results. The Residual Viscosity Rate of our PET Release film could reach 92%~94%.
The above two indicators are the most critical indicators of the release film, the stability of the silicon coating for the release force reaction, and the residual reaction is the bonding fastness between the silicone oil and the base film.
