4.5 Recommendations for problem-free operation
Note: These experiences apply for a wide variety of duel-component media. Always
follow the manufacturer recommendations for your product in addition to these.
• Mixing ratio with very short dosing times
Dual component media usually have different properties (viscosity). They therefore
emerge from the outlets with different pressures. This means that deviations in the
mixing ratio can usually be noted at the start of dosing. Selecting a suitable mixing pipe
is essential to the result.
• Retraction with duel-component media
Retraction ensures a clean break of the thread. If it is set too large, the already mixed
product enters the dispenser, causing them to react with each other.
• Note the pot life
Before breaks in work, rinsing (filling completely) the mixing pipe with one of the two
components prevents the two components from reacting inside the mixing pipe.
As it is not possible to prevent the two components from coming into contact on the
outlets, this measure is not suitable for every break in production.
