Nickel adhesion to silicone: Important cause to check

Summary for nickel adhesion to silicone Discussion

Nickel adhesion to silicone is the core issue in this thread: Swa Beng Hooi reports that silicone placed on a nickel-plated surface and cured at 150 °C for 2 hours leaks afterward, even after trying different silicone batches. Because the problem appears only with certain nickel-plated batches, the question points away from a simple silicone formulation issue and toward variability in the nickel surface itself. No answer text is included in the excerpt, so the thread does not confirm a root cause. The practical takeaway is that the nickel finish or its condition before cure is the likely variable to investigate, rather than assuming the silicone is inherently faulty. The post also asks whether nickel reactivity increases at high temperature, but the excerpt provides no expert response to confirm or deny that hypothesis.
