Auxiliary Supplies for Thermal Spray

Auxiliary Supplies for Thermal Spray

To support your thermal spray activities, we offer auxiliary supplies that include grits for surface preparation, maskants to prevent grit blasting and coating in undesired areas, and post-coat sealer materials to help coatings last longer and prevent corrodants from penetrating the coating.

Pre-coat auxiliary supplies

Blasting media (grits)

  • Metcolite high-quality alumina grit
  • Offered in several standard grain sizes
  • Designed to ensure a clean and consistent surface profile
  • Sharp-edged and hard
  • Lasts for many blast cycles


We offer several different masking options to prevent unwanted coating in specific areas:

Masking tapes

  • Designed to withstand the rigors of the thermal spray process
  • Removes cleanly after coating
  • For High Velocity Oxygen Fuel (HVOF) applications, we offer HP Flame Spray Masking Tape

Liquid masking compounds

  • Designed for masking more complex geometries 
  • Several different liquid masking products are available to suit differing production requirements
  • Easily applied
  • Washes or peels off without leaving a residue

Post-coat auxiliary supplies


To seal the inherent porosity of thermal spray coatings and further enhance corrosion resistance, use our Metcoseal portfolio of sealer materials:

  • Product choices designed for various applications and service conditions
  • Simple to apply, requiring only an air dry or a low-temperature cure in an air oven
  • Low Volatile Organic compound (VOC) and VOC-free sealers available
