Material Notes:

PERMABOND® 240 is a high viscosity product useful in large gap applications. It is ideal for porous substrates. 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: Rapid development of high strength Ease of use – no mixing or heat cure Bonds most materials 100% reactive, no solvents Information provided by Permabond.
