Handling
It is necessary to crosslink the product with Curing Agent X7 (0.5-1.5%).
After addition of crosslinker, pot-life decreases, depending on temperature and pH.
If necessary, the product can be diluted with water. Before adding Curing Agent X7, check pH value and, eventually, correct it with ammonia till pH=9.
Then add the crosslinker. Curing Agent X7 must be added slowly and under stirring, in order to obtain a good dispersion of the curing agent in the adhesive.

Storing
TACKWHITE AP 17 must be stored at temperature between +5°C and +40°C.
