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.

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).

AN280L

Aluminum
Acid Etch

AN280L is a highly efficient acid solution used for removing oxides and etching aluminum to a smooth matte finish prior to anodizing or plating. The material is non-fuming and does not contain nitric or hydroflouric acid or other dangerous acids typically associated with this process.
