Application
Efka® FA 4644 is compatible with all coating systems (solvent-free or not). The pot-life of two-pack systems is not affected. Advantages offered by using Efka® FA 4644 when dispersing organically treated bentonites are:
● shorter dispersing time
●
easier handling of the bentonite gel
●
improved storage stability
