Acid Salts and Additives

These products re available in a wide range of formulations to improve the performance of acid pickle operations.  Dry acid salts and dry acid salt additives offer accelerated oxide removal at lower costs.  Acid additives provide improved operations and extended life to acid pickling processes.

Asterion acid salts and additives are easily controlled to offer long life, reduced operating concentrations and lower operating temperatures.  These features combine to ensure economic and efficient operation.

Dry Acid Salts

Dry acid salts promote the activation of brazed and welded areas on steel parts.  Built in wetters assist other components in the formulas to accelerate oxide removal. An additive of a concentrated blend of salts and surfactants in a free flowing granular form is also available to be used with Sodium Bi-sulfate or Sulfuric Acid to prepare an electrolytic acid pickle solution. The built in wetters accelerate oxide removal. This product is less expensive to prepare and maintain than comparable dry acid salts to further reduce operating costs.

Acid Additives

These additives contain a combination of highly effective, acid resistant emulsifiers, wetting agents and dispersants to degrease parts.  These formulations enhance pickling, de-rusting and scale removal while reducing metal loss.  Formulations are non toxic and non flammable.  A new generation of acid inhibitors is available which does not form a continuous film and protects the metal by absorption to specific corrosion sites.  These products are formulated to work effectively with hydrochloric or sulfuric acid pickle operations.

These acid additives extend the acid life and improve heavy scale removal. A combination product is available with fume suppressants and wetting agents to protect the base metal from sulfuric acid, extend the useful life of the pickling solution and reduce fumes and heat loss.  This product effectively eliminates the use of up to two other products.  All Asterion Acid Additives reduce smut while assisting in the removal of dirt rust.  Asterion acid additives are easily controlled to offer long life, reduced operating concentrations and lower operating temperatures.  These features combine to ensure economic and efficient operation. Some formulations will extend the life of the acid pickle tank.

Blackening Processes

Both room temperature and traditional black oxide processes are available from Asterion. All provide the economy and high performance operation expected from Asterion Products.

Black Oxide Coatings -Asterion offers hot black oxide processes for ferrous substrates which provide an adherent, dense black oxide coating. The process produces a uniform deep black finish and provides superior performance over a wide variety of stampings, forgings and castings. Post process, the finish accepts a range of oils for a deep matte to shining gloss finish.

Copper Blackening Process – Asterion offers an outstanding copper blackening process providing a deep black to brown finish. The result may be relieved to produce a bronze appearance. It is economical and efficient to operate and may be applied over a variety of copper alloys, brass or copper electroplate. The mildly adherent finish is perfect for post finish relief with oil, or hard organic top coats.

Steel Blackening -Asterion offers a room temperature blackening process which produces a deep, dark coating for ferrous substrates.  The deposit is very adherent and requires very little maintenance.  Superior bath life, combined with low ambient temperature operation yields high efficiency and great economy.  This process is an excellent choice when a hot black oxide is not required.  The deposit readily accepts oils, top coats and lacquers for a final finish.
