Ideal for aluminum, iron and steel castings, brazings, and other ferrous parts
CastSeal™ is a uniquely formulated, 2 part, VOC free Brush-On Sealant™. The very low viscosity provides excellent wetting, and enables CastSeal™ to wick into pores, welds, and seams and between close-fitting aluminum, iron, and steel castings.DOWNLOAD SAFETY DATA SHEETS
Ideal for macro-porosity on iron, aluminum, brass, and other metal castings and part
ImSeal™ is a uniquely formulated, 2 part epoxy based macro-porosity sealant. ImSeal™ draws beneath the surface – penetrating and filling porosity deep within the wall thickness of a casting.
It fills all interconnected passageways becoming a permanent indestructible seal and is not affected by subsequent operations.DOWNLOAD SAFETY DATA SHEETS
