DE-OXIDIZING/DE-SMUTTING


Product Variants:

DYNAPREP AD

Concentrated liquid, chromium free deoxidizer and desmutter for aluminum and aluminum alloys. It is ideal for removing smuts and oxides that form in alkaline etching solutions and the resulting aluminium surface is highly active for subsequent processing. This is a non-foaming product and can used in conjunction with Dynaprep AD Booster to increase deoxidizing rate, reduce required concentration and increase bath longevity.

DYNAPREP AD #2

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. 


DYNAPREP AD #2D

Concentrated liquid, fluoride and chromium free deoxidizer and desmutter for aluminum and aluminum alloys.  Dynaprep AD #2D 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. 


DYNAPREP AD #3

Liquid, chromium free de-oxidizer and de-smutter for aluminum and aluminum alloys.  Dynaprep AD #3 is dissolved in water to provide an excellent cleaning of aluminum and aluminum alloys prior to plating, chemical conversion coating and welding. The absence of residual, slimy aluminum or magnesium salts insures a clean surface for subsequent finishing operations. 


DYNAPREP AD #3G

Powdered, chromium free de-oxidizer and de-smutter for aluminum and aluminum alloys.  Dynaprep AD#3G is dissolved in water to provide an excellent cleaning of aluminum and aluminum alloys prior to plating, chemical conversion coating and welding. The absence of residual, slimy aluminum or magnesium salts insures a clean surface for subsequent finishing operations. 


DYNAPREP AD #6

Dynaprep AD #6 is a non-chromated, easy to handle deoxidizer that quickly removes oxides, smut, mill scale and heat treating discolouration from aluminum and a wide variety of its alloys. 


DYNAPREP AD #7D

DYNAPREP AD #7D is a phosphoric acid based cleaner, brightener and pre-paint conditioner for aluminum.  DYNAPREP AD #7D should not be used on high copper bearing aluminum alloys or aluminum castings.


DYNAPREP AS No. 2

Acid Salt For Copper and Zincate Surfaces. Is a powdered product that is used with water and sulphuric acid to make a safe, highly stable solution for stripping zincate from aluminum. Can also be used to make a non-chelated, mild etch solution for copper. When used as recommended, this mixture will provide a clean, uniformly micro-etched copper surface that will readily accept electrolytic or electroless copper or nickel in printed circuit board or commercial applications.


DYNAPREP AS No. 5

Two part powdered product that are dissolved in water to produce a non fuming pickling solution for copper, copper alloys, aluminum and other non-ferrous alloys. 


DYNAPREP AS No. 7

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.
