How does silicone bond with TPU?
Silicone is a hard material to stick, so is TPU material, so how to do? In fact, the adhesion of silica gel and TPU has long been a sticking problem for silica gel products factories. How to paste silica gel and TPU to achieve a firm effect. Below, Kanglibang with you to easily solve the problem of paste.
【 Conlibond 】 TPU primer CL-25T+ instantaneous adhesive 406 combination, to paste silica gel and TPU material:
Treat the surface of TPU with treating agent CL-25T, then bake in the oven at 90°C for 15 minutes, point on the quick-drying glue (601/603), and press the silica gel and TPU material hard for 10-15 seconds to solidification. In this way, the strong bond between silica gel and TPU material can be achieved.
【 Connebang 】 The combination of treating agent CL-26AB-1 + slow drying adhesive KN-300 can be used to paste: after treating the surface of TPU with treating agent, put it in the oven at 90°C and bake it for 15 minutes. Then apply KN-300 on the adhesive surface of TPU, press it in a fixed position with an object and leave it at room temperature for 12 hours to see the effect.
How to bond silica gel and TPU - the above two sets of bonding scheme can also be satisfied? If you want to ask whether there is a hot vulcanization process to bond, some brother. After treating the surface of TPU with CL-26AB-1 primer, apply liquid silica gel to prevent injection molding in the oven.
