Moisture Sensitivity

The adhesive must not be exposed to moisture before and during application.
Moisture causes foaming leading to lower mechanical properties.

  • Preparation: For some substrates the use of mechanical pretreatment and/or cleaner or primer is necessary to achieve good adhesion.
  • Processing: Low temperatures can cause a temporary increase in viscosity resulting in reduced extrusion and slower curing rates.
  • Cleaning: Clean tools immediately after use. Once cured, the material can only be removed mechanically.
