Transport and Storage
Partial segregation may occur during transport and storage. It is therefore recommended to homogenize the DMT Dust 78|318|EEC before use, which can be achieved by mixing with a laboratory tumbler mixer. Please store in a dry and airtight original container.
Quality ensurance
In order to achieve reproducible quality, the raw materials and production are strictly controlled. The following quality controls are carried out:
Monitoring the particle size distribution of raw materials Monitoring the particle size distribution of the end product
