Material Notes:
PERMABOND® 790 is a low viscosity, surface insensitive adhesive that will rapidly bond substrates with acidic surfaces such as wood and plated surfaces. Plastics, metals, ceramics and elastomers are also rapidly bonded. The fast cure minimizes the occurrence of frosting and fogging. The wicking viscosity of this product makes it ideal for post-assembly application. 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: Extremely fast setting Rapid development of high strength Ease of use – no mixing or heat cure Surface insensitive 100% reactive, no solvents Information provided by Permabond.
