Product Description
  • HAPWELD 37 A/B is a thixotropic (putty-type) version of HAPWELD 36 A/B.
  • HAPWELD 37 has a creamy, non-sag consistency, which can be applied with a trowel, knife, or brush, and adhesive will not sag or shrink. The smooth consistency allows the user not only to use HAPWELD 37 as an adhesive, but also as a void filling and filleting putty.
  • HAPWELD 37 can be easily machined; feather edged, drilled, tapped, turned in a lathe, sanded, and polished. It is compatible and will bond to most metals, wood, plastics, ceramics, fabrics, and compositions of almost any type.
  • Another added advantage of HAPWELD 37 is that Part A is black and Part B is white. When mixed, they turn gray. This color-coding insures the user both a good homogenous mix and also allows the user to spot-check the mix ratio by color.
  • Some proven applications are: filleting spot welded metal parts, forming a radius on foundry patterns, patching of all types, anchoring bolts and machines, repairing valves, shafts, bonding magnets, and repairing pitted bearing surfaces
