Loctite® AA H3151 is a sag-resistant, two component, methacrylate adhesive system formulated to bond automotive grade cold rolled steel without the use of an external primer. H3151 provides a long open time (40-60 minutes) allowing manufacturers to correctly position parts for proper alignment. This adhesive contains 5 mil glass beads to insure adequate bondline control. Loctite® AA H3151 is an easy to use 1:1 adhesive that forms resilient bonds and maintains its strength over a wide range of temperatures. It is also suitable for bonding a wide variety of plastic and metal substrates without the use of additional primer.
