HVMC & Dichtol Sealant

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 CompoundHVMC sealant (high-velocity masking compound) is a unique two-part silicone putty that allows operators to mask holes, keyways, channels, and depressions. The compound resists ALL forms of grit blast and thermal spray.

HVMC sealant is also ideal for producing reusable plugs and molds. 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), Medium (1.0 Kg), and Large (2.0 Kg) - Larger kits are also available upon request.

Dichtol Sealant

Dichtol: Metal impregnation / capillary-active sealing of micro-porous materials

DIAMANT dichtol is the innovative ready-to-use polymer system for the capillary-active impregnation of porosities on thermally sprayed layers as well as rapid-prototyping components and castings

It serves as an individually adjustable polymer system for dipping, brushing, injecting, or spraying. Pinpoint application for maximum leak-tightness with minimum investment costs, without vacuum, without pressure.
