Material Notes:
PERMABOND® 108 is an intermediate viscosity cyanoacrylate that is used to bond through intermediate gaps. It is fast setting and suitable for use on plastics, rubber and metals. Cyanoacrylate adhesives are single component adhesives that polymerize rapidly when pressed into a thin film between parts. The moisture adsorbed on the surface initiates the curing of the adhesive. Strong bonds are developed extremely fast and on a great variety of materials. These properties make PERMABOND cyanoacrylates the ideal adhesives for high speed production lines. Features & Benefits: Fast-setting Some gap fill ability Ideal for automated dispensing Information provided by Permabond.
