Manufacturing process
1. Substrate preparation: Prior to coating with PU, TPU, or PE films, samples must be tested to determine whether they will deactivate the platinum catalyst in the silicone gel. Apply a primer coat; a coating weight of 7–10 g/m² is recommended.
2. Weigh components A and B according to a mass ratio of 1:1, mix thoroughly, and degas the mixture (either with a mixer or a static mixer; when using a static mixer, it is recommended to employ a MIXPAC™ static mixer with more than 24 sections).
3. Apply silicone gel using a coating machine; a coating weight of 100–200 g/m² is recommended, with the specific coating weight adjusted according to actual requirements.
4. At room temperature (23–25°C), manually mixed products should be used within 15 minutes (in summer, within 10 minutes; in winter, within 20 minutes), while products mixed with a static mixer should be used within 30 minutes.
5. The recommended baking temperature is between 110–120°C, and the recommended baking time is 4–5 minutes. As the baking temperature increases, the baking time can be shortened accordingly. Specific parameter settings should be confirmed based on the actual conditions at the site.
