Material Notes:
PERMABOND 798 is a high viscosity cyanoacrylate that combines fast cure with the ability to cure through a large gap. Plastics, Metals, Ceramics and elastomers are also rapidly bonded. The fast cure minimizes the occurrence of frosting and fogging. This adhesive is particularly well­suited for use on porous substrates, since it fixtures before wicking into the surface pores. 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 cure through large gaps Surface insensitive­cures rapidly on most surfaces Easy to apply and dispense 100% reactive, no solvents Typical Applications: Rubber Bonding Model Assembly Jewelry Assembly Ceramics Bonding Wood Bonding Speaker Bonding Fabric and leather bonding Soluble In Nitroethane, Methyl Ethyl Ketone, AcetoneInformation provided by Permabond.
