LOCTITE® SF 7239 Plastic Primer is a single component material, which dries rapidly at room temperature. It is suitable for use on all plastics and makes 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 similar to that described in the TDS for the particular adhesive.
