Seven structural acrylic adhesives from Henkel Corp., bond to a variety of metals, replacing mechanical fasteners. Two-part Loctite Speedbonder structural adhesives bond aluminum, steel and even galvanized metals to a variety of substrates including plastics and composites.
The H4720 Speedbonder version fixtures in just 10 to 15 minutes and provides excellent impact and peel strength on aluminum surfaces. For steel bonding, the H8500 line offers a short open time, while H8510 offers an extended open time for parts alignment. The H8600 adhesive cuts through the galvanized material to assure a solid bond without the corrosion that can cause problems over time. It also bonds to many other metals exposed to environ mental extremes.
Two general purpose formulations are also available. H3151 offers 35 to 40 minutes of open time for part adjustment, and provides solid bond strength on aluminum and steel. Loctite H4500 is a fast-setting adhesive for general metal bonding with an open time of just 10 minutes.
