Application of Polyurethane Structural Adhesive on Honeycomb Panels
In the manufacturing of honeycomb panels, adhesives play a crucial role. A honeycomb panel consists of three main components: face sheets, a honeycomb core, and a backing sheet. The face sheets and backing sheets are typically made from robust materials such as aluminum alloy, steel, or fiber-reinforced plastics, while the central honeycomb core is fabricated from lightweight materials like paper, aluminum, or plastic.

Epoxy potting compound helps enhance the performance of cooling fan motors!
As the demand for thermal management in electronic devices continues to grow, the use of cooling fans is becoming increasingly widespread. However, in environments that are humid, water‑rich, or even subject to submersion, the waterproof performance of cooling fans has become a critical factor. Encapsulating potting compounds, as high‑performance sealing materials, play a pivotal role in this regard, providing a robust waterproof barrier for cooling fan motors.
