Main features

  • Aggressive Acid-Stripping Protection
  • Visible Blue Gel Placement
  • OMat and ISO Evaluation Scope

Product Description

Dymax SpeedMask 734-BT Maskant is a blue UV/visible-light-curable gel maskant for temporary protection during aggressive chemical processing. It is stated for acid stripping with hydrochloric, nitric, and hydrofluoric acids, as well as plating, anodizing, and aggressive grit blasting. The gel format supports localized placement before light cure, while the cured barrier remains within a controlled removable-mask role. Product-specific documentation also identifies Rolls-Royce OMat 2/241 and ISO 10993-5 cytotoxicity evaluation scope; those references must remain tied to the exact stated conditions.

Key features

  • Acid-stripping protection: The cured mask is documented for hydrochloric, nitric, and hydrofluoric acid stripping processes.
  • Blue gel placement: The gel form supports visible, localized coverage before light cure.
  • Controlled qualification scope: OMat 2/241 and ISO 10993-5 references apply only within the exact product documentation.

Applications / Suitable for

  • Acid stripping
  • Plating and anodizing
  • Aggressive grit blasting and orthopedic implant process protection

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.
