Permabond® 4C30 – Medical-grade instant adhesive for gaps and challenging materials
Permabond® 4C30 is a single-component, medium-viscosity instant adhesive specially developed for industrial and medical applications with gaps up to 0.38 mm. Thanks to its high reactivity, it achieves hand strength within 15 seconds on a wide range of materials such as metal, rubber, and plastic. The adhesive is particularly suitable for automated dispensing and high-speed production processes. Thanks to its proven biocompatibility in accordance with ISO 10993-5 and USP Class VI , Permabond® 4C30 is ideal for medical technology applications, such as the manufacture of disposable products or assembly processes in medical device manufacturing.
