DYMAX 758-H

Main features

  • Light Cure with Heat Backup
  • Aggressive Acid-Process Protection
  • Peel or Incineration Removal

Product Description

Dymax SpeedMask 758-H Maskant is a red opaque gel maskant for acid stripping, plating-bath exposure, and aggressive grit blasting on titanium and nickel alloys. The material cures with LED or UV/visible light and includes secondary heat cure for internal passages or other shadowed areas that are difficult to expose directly. Its application behavior supports spraying and trimming before or during process preparation. After the protected operation, the mask can be removed by peeling or incineration within the stated chemical, geometry, and cure conditions.

Key features

  • Light cure with heat backup: LED or UV/visible exposure provides primary cure, with secondary heat cure for internal passages.
  • Acid-process resistance: The cured mask is documented for acid stripping and plating-bath protection.
  • Adaptable removal: The temporary barrier supports peel or incineration removal after processing.

Applications / Suitable for

  • Acid stripping
  • Plating-bath protection
  • Aggressive grit blasting on titanium and nickel 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

Thermal Properties
Glass Transition Temperature (Tg)
The glass transition temperature for organic adhesives is a temperature region where the polymers change from glassy and brittle to soft and rubbery. Increasing the temperature further continues the softening process as the viscosity drops too. Temperatures between the glass transition temperature and below the decomposition point of the adhesive are the best region for bonding. The glass-transition temperature Tg of a material characterizes the range of temperatures over which this glass transition occurs.
