PrimeStop SC

PrimeStop SC is a premium interaction barrier/stop-off water-based coating of Alpha Silicon Carbide (SiC).  Usable to over 1100 C with many molten materials, and particularly useful for Aluminum-Lithium (Al-Li) melts.


Key Attributes

  • Non-reactive with most materials
  • Relatively inert with molten Al-Li alloys
  • Good with all substrates/atmospheres to >1100 C
  • High emissivity/high thermal conductivity
  • Water-based, easy to use/cleanup

Ideal Uses

  • Molten Al-Li alloys and nonferrous metal processing
  • Barrier stop-off for diffusion/reactions/interactions
  • Whenever high emissivity/blackbody coating is required
