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.
Earlier this year paralyzed IndyCar drive Sam Schmidt did the seemingly impossible -- opening the qualifying rounds at Indy by driving a modified Corvette C7 Stingray around the Indianapolis Motor Speedway.
Wearables are changing the way we see ourselves. With onboard sensors that have access to our bodies, we are starting to know our physical selves like never before, quantifying our activity, our heart rate, breathing, and even our muscle effort.
Last week, the bill for reforming chemical regulation, the TSCA Modernization Act of 2015, passed the House. If it or a similar bill becomes law, the effects on cost and availability of adhesives and plastics incorporating these substances are not yet clear.
This year, Design News is getting a head start on the Fourth of July celebration. In honor of our country and its legacy of engineering innovation -- in all of its forms -- we are taking you on an alphabetical tour through all 50 states to showcase interesting engineering breakthroughs and historically significant events.
