DCHZ-405 Gold Conversion Coating Process for Aluminum
DCHZ-405 is used to produce the maximum corrosion resistant chromate finishes on all aluminum
alloys, can quickly form a gold color conversion film.
Product Characteristic
1. It is easy to control, long life, low cost.
2. Strong adhesiveness, suitable for passivation treatment prior to powder coating or painting.
3.The conversion film has conductivity.
4. Strong corrosion resistance, offers high salt spray resistance of over 100 hours.

Solution Control
The strength of the solution is maintained by adding the concentrate. Dealing with one ton
aluminum will consume 3-5kg DCHZ-405A and 3-5kg DCHZ-405B. The amount of additions
determined by the consumption.
Caution
DCHZ-405 solutions are strongly acidic. Do not get in eyes, on skin or clothing. While preparing
and working with solutions, wear goggles or face shield, rubber gloves and rubber apron. In case of
contact with skin or eyes, flush freely with water for at least 15 minutes. For eyes, call a physician.
