Thermal Spray Masking Compound

When the use of masking tapes and fabrics becomes difficult due to challenging geometrical shapes and profiles, Masking Compounds often provide the best solution.

High Velocity Masking Compound (HVMC)
Highly effective for masking difficult openings, crevices and contours, HVMC can be used to form reusable masking plugs, caps, and moulds. HVMC stands up to all forms of thermal spray and surface treatment.

HVMC is a unique two-part silicone putty that allows operators to mask holes, keyways, channels, and depressions. HVMC is also ideal for producing reusable plugs and moulds. This compound bonds well to all GBI silicone coated glass tapes to provide a mask resistant to all forms of surface treatment including the most powerful forms of HVOF (High Velocity Oxy Fuel) spray systems. 


The HVMC Kits are typically sold in the following sizes:

  • Small (0.5 Kg)
  • Large (2.0 Kg)
  • Larger kits are also available upon request
