Seal Your Pores
CastSeal, a brush-on methacrylate compound formulated for sealing porosity in cast iron parts that will contain gases under pressure, or liquids, has been developed by IMPCO (East Providence, RI). The low dynamic viscosity enables it to wick deeply into pores and seams between close-fitting ferrous metal surfaces. After CastSeal has cured, the excess material can easily be rinsed away. Other features include:
- A shelf life of 6 to 12 months.
- The ability to apply the sealant with a brush.
- An operating temperature range of up to 355°F.
