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
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.
Most cyber attacks could be avoided by adopting a list of Critical Security Controls that were created by the Center for Internet Security. That’s the message from Steve Mustard of the Automation Federation.
How 3D printing fits into the digital thread, and the relationship between its uses for prototyping and for manufacturing, was the subject of a talk by Proto Labs' Rich Baker at last week's Design & Manufacturing Minneapolis.
