Mixing

What is the most suitable mixing method?

If a 2C material is selected, the next step is to choose a mixing method.

Static

In static mixing, the two components are brought together and mixed homogeneously in a plastic tube containing several mixing helixes, each rotated by 90°. The two components are optimally mixed thanks to the helical surfaces arranged one behind the other. Due to this simple process and the low maintenance requirements, static mixing is an efficient and cost-effective solution.

AdvantagesDisadvantages
Cost-effectiveNot recyclable
Easy to usePoor for mixing ratios
Low process relevancePoor for large viscosity differences
No maintenance requiredPoor for short pot life


Dynamic

Dynamic mixing involves feeding the two components into a chamber with a given mixing ratio, where they are mixed by a rotating agitator. There is no mixing and thus no reaction before the components meet in the mixing chamber. This method allows a very effective and homogeneous mixing of both educts.

AdvantagesDisadvantages
Suitable for unbalanced mixing ratiosCleaning necessary during breaks/downtimes
Suitable for very small quantitiesExpensive
Suitable for short pot livesComplex handling / process complexity
