B770 is used to make polyolefin and other low energy surfaces suitable for bonding with Bondloc cyanoacrylate adhesives. It is only recommended for difficult to bond substrates which include polyethylene, polypropylene, polytetrafluoroethylene (PTFE) and thermoplastic rubber materials. B770 is not recommended in assemblies where high peel strength is required.


B770 primer should be used here difficult to bond surfaces such as shiny plastics (polyethylene), PTFE and polyolefins such as polypropylene, require bonding to themselves in combination or to less difficult surfaces. B770 works by increasing surface adhesion on low energy substrates. Test should be conducted to access suitability.
