METHOD FOR PRODUCING RELEASE LINER |
摘要 |
Efficiently produced is a release liner including a plant-derived film as a substrate and having a good appearance, releasability, and adhesion. A method according to the present invention produces a release liner having a plant-derived film substrate and, on at least one side thereof, a release coat layer derived from a thermosetting silicone resin. The method includes the steps as follows:
Step A of applying a thermosetting silicone release agent to at least one side of a plant-derived film substrate, the release agent containing 100 parts by weight of a thermosetting silicone resin and 0.05 to 0.55 part by weight of a curing catalyst;
Step B of drying at 40°C to 90°C for 10 to 60 seconds after Step A;
Step C of applying an ultraviolet ray at 50 to 300 mJ/cm 2 after Step B; and
Step D of aging at 30°C to 70°C for 12 to 240 hours after Step C. |
