This is mainly caused by the reaction between glass adhesive and PVC adhesive strips. In order to reduce costs, some businesses add more calcium carbonate substances to PVC adhesive strips, and calcium carbonate will react with silicone adhesive, and the phenomenon of yellowing will occur. This is mainly the cause of the rubber strips. If you choose a glass glue product with guaranteed quality, please check the quality of the rubber strip. If it is poor quality of glass glue, the greater the range of yellowing nature. To avoid this problem, it's best not to use tape; Or choose a good rubber strip, good glass glue. At the same time, we emphasize that before engineering glue is used, it is best to do a compatibility test to see whether the glass glue product is soluble with other materials before deciding whether to use it or not.
