Brush-On Methacrylate Compound

Brush-On Methacrylate Compound

CastSeal is a brush-on methacrylate compound formulated for sealing porosity in cast iron parts that will contain gases under pressure or liquids. CastSeal's low dynamic viscosity enables it to wick deeply into pores and seams and between close-fitting ferrous metal surfaces. After CastSeal has cured in the porosity or voids, excess material on the surface is easily rinsed away with water, leaving the surface clean and ready for painting or other operations. CastSeal does not alter critical surface dimensions.

CastSeal comes packaged in a 250ml kit with a shelf life of 6-12 months. Mixing the sealant's two components creates a VOC-free, low-viscosity, pale-blue liquid that can be applied by brush. Once mixed, CastSeal has an extended pot life of about one day, allowing multiple parts to be treated from the same kit. Drawing a vacuum improves penetration. CastSeal's chemistry allows easy cleanup of parts, tools, and brushes with water - no detergents or solvents are required. Cured CastSeal forms a pressure-tight mass that withstands continuous service temperatures of up to 179C (355 F). Parts treated with CastSeal have been tested leak-free at over 150psi. Cured CastSeal has a typical hardness of 95 Shore D (ASTM D2240) and exhibits resistance to a broad range of chemicals, including oils, glycol, chlorinated and fluorinated solvents, mild caustics, acid solutions and water.
