Product characteristics

KORYNT 3160 is an aqueous solution of modified ammonium compounds. 


KORYNT 3160 is a passivating agent for iron, steel and cast iron. It provides a medium term rust protection. Passivation bath is applied by spraying or submersion. The agent can be also used for cleaning brass objects. 

Product Features

KORYNT 3160 is flavescent coloured, moderately viscous liquid that can be mixed with water in any ratio. 

KORYNT 3160 must comply with the following quality characteristics:

Directions for Use

KORYNT 3160 is very soluble in cold water. Recommended concentration of the passivation bath ranges from 0.5 to 1.5 % (from 5 to 15 litres of the agent per 1000 litres of the bath). Recommended temperature for passivation is between 30 to 40 °C. The agent should be allowed to take effect for 3 to 5 minutes.At lower operating temperatures, it is necessary to increase both the agent's concentration and the time for which it is taking effect.The operating bath is "being depleted" during its application - content of the active component of the agent is decreasing. Consequently, it is necessary to monitor the value this content. This monitoring is usually performed by determining alkaline concentration of the bath. 

Packaging & Storage

KORYNT 3160 is delivered in 50 l PE bottles. Alternatively, it can be delivered in different containers that were discussed and agreed on in advance. Store it in a sealed container in places protected from direct climatic influences. Recommended storage temperature is between +5 to +25 °C. Short-term exposure to lower temperatures, e.g. during transport, does not affect product's application properties. 


KORYNT 3160 is transported by covered vehicles in compliance with ADR/RID Regulations. 


Provided the product is transported and stored in accordance with the above written conditions, its warranty is 6 months from the production date.
