How to solve the problem of sticky screen printing silicone?
1. Optimize materials
Choose suitable silicone: Use silicone with a smooth surface and non-sticky after curing.
Add additives: Add anti-sticking agent or slip agent to reduce surface stickiness.
2. Adjust curing conditions
Ensure full curing: Follow the curing requirements of silicone to ensure complete curing and avoid sticking of uncured parts.
Control temperature and time: Appropriately increase the curing temperature or extend the curing time to ensure that the silicone is completely cross-linked.
3. Surface treatment
Coating treatment: Apply anti-stick coating, such as fluorine coating or UV coating, to the surface of silicone.
Use release agent: Use release agent on the mold or work surface to reduce silicone adhesion.
4. Improve the process
Control the thickness of silicone: Avoid too thick to ensure uniform curing.
Use protective film: Cover the protective film after curing to prevent the surface from sticking.
5. Post-processing
Clean the surface: Use a dust-free cloth or alcohol to clean the surface and remove residues.
Secondary curing: Perform secondary curing to further reduce stickiness.
6. Environmental Control
Control humidity: Maintain proper humidity to avoid high humidity environment that causes the silicone surface to become sticky.
Clean work area: Ensure the operating environment is clean and reduce dust and impurities.
