LOCTITE 406 is designed for bonding of plastics and elastomeric materials where very fast fixturing is required.
Under normal conditions, the atmospheric moisture initiates the curing process. Although full functional strength is developed in a relatively short time, curing continues for at least 24 hours before full chemical/solvent resistance is developed.
LOCTITE 770 is used to make polyolefin and other low energy surfaces suitable for bonding with Loctite cyanoacrylate adhesives. On such treated surfaces the cured performance of LOCTITE cyanoacrylate adhesives is generally similar to that described in the TDS for the relevant adhesive.
It is only recommended for difficult to bond substrates which include polyethylene, polypropylene, polytetrafluoroethylene (PTFE) and thermoplastic rubber materials.
LOCTITE 770 Polyolefin Primer is not recommended in assemblies where high peel strength is required.
