Stop Porosity, Leaks

Fri, 03/11/2011 - 3:53am

WeldSeal from IMPCO Inc.(East Providence, RI) is a brush-on methacrylate compound formulated for sealing porosity in welds that will contain gases under pressure, or liquids. The low dynamic viscosity allows it to move into pores and seams, or close-fitting ferrous metal surfaces. Additional benefits include:

  • A mixture that is a VOC-free, low-viscosity, and pale blue liquid that can be easily applied by a brush.
  • An extended pot life of about one day, allowing multiple parts to be treated from the same kit.
  • The ability to withstand temperatures up to 355°F and leak-free pressures at more than 150psi.
  • A hardness of 95 Shore D (ASTM D2240) and resistance to oils, solvents, caustics, and more.
