Main features

  • High-Temperature Thermal-Spray Masking
  • Aggressive Blast-Media Resilience
  • Flexible Post-Process Removal

Product Description

Dymax SpeedMask 750 Maskant is a pink UV/visible-light-curable gel maskant for temporary protection during high-temperature thermal-spray coating and aggressive grit-blasting operations. The material supports high adhesion and tack-free cure, helping the mask remain in place while exposed to plasma spray, HVOF, wire arc, and related blast-media conditions. Supported substrates include nickel, titanium, and cobalt-chrome alloys. After processing, the cured mask can be removed by incineration or by warm-water and air-assisted methods within the stated process conditions.

Key features

  • Pink gel coverage: The colored gel supports controlled placement on selected alloy surfaces before cure.
  • Thermal-spray resilience: The cured mask is documented for high-temperature spray and aggressive blast-media exposure.
  • Multiple removal routes: Post-process removal can use incineration or warm-water and air-assisted methods.

Applications / Suitable for

  • High-temperature plasma spray and HVOF
  • Wire arc and thermal-spray coating
  • Aggressive grit blasting on nickel, titanium, and cobalt-chrome alloys

Mechanical Properties
Elongation
Elongation is the process of lengthening something. It is a percentage that measures the initial, unstressed, length compared to the length of the material right before it breaks. It is commonly referred to as Ultimate Elongation or Tensile Elongation at break.

Physical Properties
Viscosity
Viscosity is a measurement of a fluid’s resistance to flow. Viscosity is commonly measured in centiPoise (cP). One cP is defined as the viscosity of water and all other viscosities are derived from this base. MPa is another common unit with a 1:1 conversion to cP. A product like honey would have a much higher viscosity -around 10,000 cPs- compared to water. As a result, honey would flow much slower out of a tipped glass than water would. The viscosity of a material can be decreased with an increase in temperature in order to better suit an application
