Handling

TACKWHITE AP 79 is ready to coat by Mayer bar or air knife coating systems; higher viscosity versions can be supplied on request for rotating blade or direct knife coating systems.
If necessary, it can be diluted with water.
The product can be cured with a small amount of Curing Agent X7 (0,5-1%), this crosslinker works better at high pH, so, if necessary, we suggest to add ammonia to reach pH = 9.

Packaging

The product is supplied in iron drums (200 kg); IBC containers (1000 kg).

Storing

TACKWHITE AP 79 must be stored at temperatures between +5°C and +40°C.
Keep containers well sealed, in order to avoid surface skin formation.

Use within 6 months from production date (unopened and in the original packaging).
