Whether using a silicone adhesive in an aerospace assembly or manufacturing silicone bakeware, post-cure for silicone is not a process that belongs in the past.
Original equipment manufacturers (OEMs) may find that post-curing can bring value to certain applications. To determine if post-cure is the best option, it’s important to better understand what is happening during the process, the advantages it offers, and key best practices.
Inspired by examples of hierarchical structures improving the properties of soft materials, the authors have explored methods to apply these concepts to waterborne acrylic PSAs made by emulsion polymerization. In this work, they attempted to build a sacrificial bond network into a PSA through multistage emulsion polymerization.
