Stop Porosity, Leaks
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.
