LOCTITE SF 770 is a primer used to make polyolefins and other surfaces with low surface energy, suitable for bonding with LOCTITE instant adhesives
The curing power of LOCTITE instant adhesives is increased on such pre-treated surfaces
The primer is only recommended for substrates that are difficult to bond, including polyethylene, polypropylene, polytetrafluoroethylene (PTFE) and thermoplastic rubber materials
LOCTITE SF 770 is not recommended in structures where high peel strength is required.
