Description

Designed as a biodegradable liquid, concentrated, medium acid detergent. The pH value of the concentrate is 1,6.

Removes impurities such as

• mineral greases and oils;
• remains of polishing pastes;
• oxide layers;
• rust;
• calcium carbonate.

Safe to use on

Cleaning – stainless steel, light and non-ferrous metals and materials (prochrome, aluminum, copper, brass, glass, plastic, etc.).

Passivation – stainless steel, aluminum, as well as metals containing chromium.

AS-METALPASS-1 dosage

Ultrasonic cleaning: make a solution of 2% (till 5%, it depends on pollution degree) with deionized or demineralized water. The recommended temperature of the working solution is 30 – 80°C. We recommend to test the cleaning concentrate on an inconspicuous spot before use.

Passivation: make a solution of 10-20%. The working temperature is 30 – 80°C. Passivation time – 10-30 min. Passivation is recommended after cleaning the metal from protective layers (mineral grease or oil). For AlSl 316 steel, the required passivation time at the working solution temperature of 70°C is 20 minutes.

The passivation of stainless steels is based on the iron atoms removal from the object’s surface, and thus increasing the concentration of chromium atoms on the surface.

Advantages

• after cleaning, copper and brass are restored to their shine;
• it does not contain phosphates or silicates.
• this detergent is biodegradable and the used working solution can be discharged into the city sewer after neutralization.
