Impco Inc.'s WeldSeal
is a high-performance brush-on methacrylate compound formulated for sealing
porosity in welds that will contain gases under pressure or liquids. WeldSeal's low dynamic viscosity enables it
to wick deeply into pores, seams and between close-fitting ferrous metal
surfaces. After WeldSeal has cured in
the porosity or voids, excess material on the surface is rinsed away with water,
leaving the surface clean and ready for painting or other operations. WeldSeal does not alter critical surface
WeldSealcomes 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 easily applied by
brush. Once mixed, WeldSeal has an
extended pot life of about one day, allowing multiple parts to be treated from
the same kit. Drawing a vacuum improves
penetration. WeldSeal's unique chemistry
allows cleanup of parts, tools and brushes with water - no detergents or
solvents are required. Cured WeldSeal forms
a pressure-tight mass that withstands continuous service temperatures of up to
179C (355F). Parts treated with WeldSeal
have been tested leak-free at over 150psi.
Cured WeldSeal 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.
Why would the biggest connector company in the world design and build the first fully functional 3D-printed motorcycle? To show TE Connectivity's engineers what the technology can really do in making working load-bearing production parts, and free up their thinking when approaching design problems.
The enhanced ST8 includes new functionality designed to help users accelerate design speed and improve the user’s ability to leverage synchronous technology. The update offers greater flexibility in choice of platform and purchasing options, according to the company.
“How can European standards affect me, especially since I only use machines built in the US?” This is a common question, and one way to answer this is to look at how machine safety is enforced, where the information comes from, and how well you can prove you followed the regulations.
