Material Notes:

PERMABOND® 268 is a medium-high viscosity cyanoacrylate for large gap fill applications. Permabond® 268 provides faster set times and improved gap-filling capability compared to conventional cyanoacrylates. The adhesive bonds to a wide range of substrates including metals, ceramics, plastics and elastomers. It is excellent for bonding difficult-to-bond plastics such as polyacetals. It can also be used on passivated metal surfaces. Features & Benefits: Versatile and general purpose Good gap fill ability Instant setting Information provided by Permabond.
