LITHSOLVENT 620

LITHSOLVENT 620 is a highly effective inhibitor formulation to protect metallic materials during chemical cleaning or pickling with hydrochloric acid or hydrochloric acid/hydrofluoric acid mixtures.

LITHSOLVENT 620 properties:
-LITHSOLVENT 620 is effective at temperatures up to 90°C

-LITHSOLVENT 620 for cast iron the maximum working temperature is 40°C.

-LITHSOLVENT 620 is suitable for hydrochloric acid and hydrochloric acid / hydrofluoric acid mixtures.

-LITHSOLVENT 620 dissolves immediately when added to dilute or concentrated hydrochloric acid.

-LITHSOLVENT 620 is also stable in concentrated hydrochloric acid (25 - 33%). 
This property is of great importance for the production of inhibited acids, which may have to be stored for a long time before being used.

-LITHSOLVENT 620 contains a combination of specific inhibitors and special surfactants with a high wetting effect. 
By reducing the interfacial tension, rapid wetting of the surfaces to be cleaned is guaranteed.

-LITHSOLVENT 620 does not impair the dissolution of deposits as well as mill scale and glow scale.

-LITHSOLVENT 620 is currently Available in pack sizes of 60kg, 200kg and 1,000kg.

Characterisation of LITHSOLVENT 620:
LITHSOLVENT 620 is a blend of alkynol and quaternary ammonium compounds, cationic.

Application area of LITHSOLVENT 620:
LITHSOLVENT 620 is used for acidic cleaning, when using hydrochloric acid (usually 5%) protects steel and copper.


LITHSOLVENT 620 protects the following materials in the temperature range specified above:
-normal steels
-Special steels (e.g. superheater and low-temperature steels)
-copper-based alloys
-Cast iron (only up to max. 40°C)

Aluminum and light metal alloys as well as zinc, tin and hard chrome are not adequately protected.


LITHSOLVENT types are inhibitors which prevent acid attack on the material to be cleaned during acidic cleaning. 
The experience of several decades with various questions regarding the removal of disturbing scales has led to the development of a wide choice of inhibitors. 
Depending on the type of acid, temperature, cleaning time and materials, the most effective inhibitor will be recommended.

Unless known, rates of mass loss with and without inhibitor are measured in the laboratory to record the subsequent protective effect in terms of numbers. 
Many scales are so difficult to dissolve that our customers use our experience with acids and acid mixtures and their effective inhibition.

LITHSOLVENT cleaners are ready-to-use mixtures of acid and inhibitor for customers who do not have the ability to prepare cleaning solutions themselves. 
In general, it is inhibited by formic acid, hydrochloric acid and phosphoric acid formulated for different temperatures and cleaning materials.
