What is the most suitable mixing method?
If a 2C material is selected, the next step is to choose a mixing method.
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.
|Easy to use||Poor for mixing ratios|
|Low process relevance||Poor for large viscosity differences|
|No maintenance required||Poor for short pot life|
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.
|Suitable for unbalanced mixing ratios||Cleaning necessary during breaks/downtimes|
|Suitable for very small quantities||Expensive|
|Suitable for short pot lives||Complex handling / process complexity|
