WeldSeal, a brush-on methacylate compound formulated for sealing porosity in welds that well contain gases under pressure or liquids, is now available from IMPCO Inc. (East Providence, RI). The WeldSeals low dynamic viscosity enables it to wick into pores and seams, allowing any excess material on the surface to be easily rinsed away with water. WeldSeal does not alter critical surface dimensions. Other benefits include:
- A VOC-free compound that is pale blue, and 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 continuous service temperatures up to 355°F. The company also claims the product has been tested leak-free at more than 150 psi.
