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.
Because of the increasing ubiquity of wearable technology, it would be easy to think that design of wearable devices is routine and involves common design and engineering knowledge. Missed efforts in development will be remembered once the devices are used in the field
This grab-bag of new fasteners and adhesives work with a range of materials they can attach to, as well as a wide variety of applications. Several are for use in consumer applications, such as wearables or other compact electronic assemblies, and some of the adhesives have extended service temperature ranges and cure at room temperature.
As governments, associations, and NGOs around the world seek to protect consumers, national and regional standards are becoming mandatory, challenging manufacturers and making testing and certification necessary for any product developed and brought to market.
