Usage Instructions
  • Mix well at room temperature, the contents of the adhesive container before removing material.
  • For optimum mixing and mix ratio accuracy, we recommend that batch sizes be not smaller than 25 grams and that the weighing tolerances be within ±5%.
  • Add the designated activator to the preweighed adhesive and mix thoroughly.
  • In some applications, warming the substrate to 120°F will aid the flow during application. Cure as indicated.
