Breaking through the smart wearable bonding challenge: How Ancham® AP9161 achieves the leap from "manufacturing" to "smart manufacturing

With the growing popularity of wearable devices such as smartwatches, fitness bands, AR/VR glasses, and smart headphones, the market is demanding with design aesthetics, comfort, durability, and functionality. Devices are evolving to be thinner, frameless, with high water resistance ratings (e.g., IP67/8), and more robust and durable. Traditional bonding solutions, such as pressure-sensitive tapes or cyanoacrylate adhesives, are gradually showing limitations in addressing these: pressure-sensitive tapes may creep under long-term mechanical stress and lack sealing integrity; cyanoacrylate adhesives are brittle, impact-resistant, and resistant to aging. Against this backdrop, PUR (Polyurethane Reactive Hot-Melt Adhesive), with its unique performance advantages, has become an indispensable key material in precision electronic assembly.
