OEMA CUPAS 806
OEMA CUPAS 806 is a concentrated ferrous sulphate solution designed for the passivation and film maintenance of seawater cooling systems. OEMA CUPAS 806 provides the passive oxide layer or patina layer formed on all copper-based alloys. This layer provides the metal with a level of protection when exposed to harsh environmental conditions and is essential for the prevention of localised erosion and corrosion. OEMA CUPAS 806 provides a non-toxic alternative to previously used Azole or SDD chemicals. OEMA CUPAS 806 can be used as a passivation chemical prior to being commissioned or after acid cleaning and can also be used as film maintenance.
