Concentrated liquid, fluoride and chromium free deoxidizer and desmutter for aluminum and aluminum alloys. Dynaprep AD #2 is also an excellent acidic, mild etch for aluminum, aluminum alloys, and magnesium alloys prior to electroplating, anodizing, welding or chemical conversion coating. The absence of residual, slimy aluminum or magnesium salts insures a clean surface for subsequent finishing operations.
Liquid, acidic etch formulated for a wide range of aluminium alloys, steel, brass, copper and zinc. It provides a mild, uniform etch that can be controlled by adjusting the solution concentration and temperature. It is also suitable to clean, steel, copper, brass and zinc parts.
Liquid, acidic etch formulated to provide a fine matte satin finish on aluminium and aluminium alloys prior to anodizing. Dynaprep AE 738 will produce a very matte finish with significantly less aluminum removal than typical etch solutions
DYNAPREP AE ADDITIVE #1 is an aluminum etch additive formulated to prevent sludge and scale while significantly extending the etch bath life. DYNAPREP AE ADDITIVE #1 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 DYNAPREP AE ADDITIVE #1 is very cost effective as it is designed to be used with plain caustic soda.
DYNAPREP AE-G2 is a concentrated powdered, alkaline etch for aluminium and aluminium alloys. This product is formulated with an inhibitive grain-refining agent for controlled etching, and chelating agents to prevent the formation of aluminum oxide sludge. This reduces the necessity of dumping or decanting the tank and, in turn, reduces waste treatment costs versus straight caustic soda or other proprietary etches.
DYNAPREP AS No.7 is a powdered, fluoride-containing acid salt used in acid treatment and etching of various metals. In many cases, it can be used to replace hydrofluoric acid, and is much safer to use since it is granular.
1 Kg of DYNAPREP AS No.7, when used with a strong acid, will liberate 1.35 Kg (1L) of 52% hydrofluoric acid.
