Loctite has made the assembly of difficult to bond thermoplastic components easier and better by adding Loctite®.
LOCTITE® 3030 Polyolefin Bonder enables manufacturers to expand their design options, boost productivity and improve product performance. This new 2-component, thixotropic acrylic adhesive eliminates mechanical fasteners, plastic welding, surface treatments, messy hot melt or solvent-based adhesives and primers. The new 3030 Polyolefin Bonder sets quickly to let you get your product assembled and out the door faster and easier.
Loctite® 3030 Polyolefin Bonder is designed primarily to bond many low energy substrates such as polyethylene and polypropylene, and can be used as a general-purpose adhesive on many other substrates.
