Etch & Etch Extenders

AN200

Aluminum
Etch

AN200 is a proprietary powdered aluminum etch that provides a consistent, even, matte finish. AN200 prevents the sludge and scale buildup normally associated with caustic etching.

AN210L

Aluminum Etch-Liquid

AN210L is a proprietary liquid aluminum etch, designed for ease of use.  Easily added to the bath by tank-side additions or metering, AN210L eliminates the dusting often associated with powdered etch.  AN210L is formulated to give a very smooth, even, matte finish while eliminating the build-up of sludge and scale in the bath.

AN250L is an aluminum etch additive formulated to prevent sludge and scale while significantly extending the etch bath life. AN250L provides better bath control and allows the operation of the etch bath at higher levels of dissolved aluminum. This reduces the necessity of dumping or decanting the tank. This, in turn, reduces waste treatment costs versus straight caustic soda or other proprietary etches. Additionally AN250L saves money as it is designed to be operated most cost effectively when used with plain caustic soda (AN250L can also be used with proprietary etches such as AN200 or AN210L).
