GIT-ZIMAX is a carrier brightener to provide the basic brightness and ductility to the deposit, and also acts synergistically with the main brightener GIT-H700 to maintain maximum, brightness and levelling.
It also insures proper chrome receptivity.
A high concentration has no harmful effect on performance, unless it is extremely high, in which case, and extra addition of GIT-H700 brightener is required to produce high quality bright deposits.
