Usage Process
1. Base material (PU/TPU/PE film needs to be sampled and tested before coating to see if it will make the platinum catalyst in the silicone gel ineffective), coated with primer, the recommended coating weight is 7-10g/m2.
2. Weigh components A and B at a ratio of 1:1, mix thoroughly and defoam (can be mixed with a mixer or a static mixer, when mixing with a static mixer it is recommended to use a MIXPAC™ static mixer with more than 24 sections).
3. Use the coating machine to coat the silicone gel, the recommended coating weight is 100-200g/m2, the specific coating weight according to the actual needs.
4. At room temperature of 23-25℃, it is recommended to use the product within 15 minutes (10 minutes in summer and 20 minutes in winter) for hand mixing and 30 minutes for static mixer mixing.
5. The baking temperature is recommended to be between 110-120℃, the baking time is recommended to be between 4-5 minutes, the baking time can be shortened accordingly with the increase of the baking temperature, the specific parameter settings need to be confirmed according to the actual situation on site.
