Dirko™ HT oxime (grey / beige / black)

Dirko™ HT oxime (neutral curing) is a highquality, high temperature resistant single component silicone-based sealing compound that exhibits permanently resilient properties. It provides excellent adhesion on all standard metals, cast iron, plastics (except for PE, PP and PTFE) and glass. Due to a reaction with humidity in the air Dirko™ HT oxime cures to form silicone. The product can be used for a very wide range of applications.

2.2 Media resistence

To demonstrate the media resistance of the sealing compound, the test specimens are stored in the relevant medium for the specified duration. The tensile shear strength is then determined (ISO 4587). The following table shows the percentage variation in the tensile shear strength from the initial value without the influence of the medium.

2.3 Curing rate

The curing rate depends on the temperature and humidity. The higher the temperature and the humidity, the faster DirkoTM HT oxime cures to form silicone. The lower diagram shows the progression of the curing rate over time in a standard climate (23°C/50% relative humidity).
 

2.4 Surface adhesion

The adhesion of Dirko™ HT oxime on different surfaces plays a crucial role in its use as a surface seal. The following figures show the measured tensile shear strength for a sealing gap of 1 mm (ISO 4587).

3. General information

3.1 Usage and processing instructions:

  • Remove sealant residues and clean the sealing surfaces with solvent
  • Sealing surfaces must be clean, dry, and free of oil or grease before applying the sealing compound in order to ensure reliable sealing and adhesion
  • Processing temperature (ambient / adhesion surface temperature): +5 to +35°C
  • Apply the sealing compound evenly across the entire surface
  • Immediately remove any excess sealing compound applied, as there is a risk that it could drip into the interior
  • Depending on the application, the parts can be fitted immediately after application, after skin formation or after complete curing
  • Fit the components in line with the manufacturer’s specifications
  • The sealing function is immediate
  • After use, reseal the sealing compound securely
  • Safety and technical data sheet at www.elring.com

3.2 Storage

  • Optimum storage conditions: Cool (+5°C to +25°C) and dry location
  • Minimum shelf life: 12 months in unopened containers
    Seal opened containers securely and use up as soon as possible
  • The batch number has the following structure: YYWWCCCCC (filling date)
