- System Preparation
Mix the two component with a meter-mix dispensing equipment or manually as follows:
Weigh the desired amount of resin into a mixing container, add the corresponding amount of hardener to the resin. Mix thoroughly by means of mechanical mixer or manually. Be sure to scrape the sides and walls of the mixing container during mixing. Check for uniform color as a sign of complete mixing. A minimum of one minute mixing time is being suggested - three to five minutes mixing time is optimal.
For potting or encapsulating applications, dispense or pour directly into the area to be filled. To minimize air bubbles, de-gas under vacuum prior to potting and pour the material into the area to be filled (preferably at the lowest point). Do not move the stream of liquid back and forth as this may entrap air. Allow the material to slowly flow around and through the subcomponents to be encapsulated. Keep the stream of material thin and continuous to assist in breaking any bubbles which may be present and to prevent the introduction of additional air.
