Our code 4904 is a primary Bondcoat powder containing Nickel and Aluminum. When flame sprayed, the particles go through a metallurgical phase change allowing self-bonding to oxide-free clean surfaces (except Copper).

Specially formulated “2 Step” metallizing powders for all low temperature powder spray torches.

  • Special “inert gas atomized” powder for ultimate cleanliness.
  • Particle size distribution designed to eliminate fuming.
  • Designed to perform well through most applicators available.
