ActivPak
Use Zerust®/Excor® ActivPak® for fast acting corrosion protection in aggressive environments such as factories, salt air, waste treatment facilities and power plants. The packets reduce flash rust and corrosion incidents, even on contaminated parts and in challenging environments.
Availabilty:
Zerust ActivPak(LS)-35 is available in many stock and custom options. Contact Harita-NTI account manager for pricing and availability.
Protection Type:
Ferrous and aluminum protection. Protects yellow metals when used as instructed. Do not place in direct contact with copper, brass or zinc and test before use.
Protection Life:
Refer to table. Seal or limit air exchange within the enclosure to maximize the protection life.

Zerust® diffusers are easy-to-use corrosion protection products that contain patented Zerust corrosion inhibiting technology. Zerust diffusers come in different formats to meet your specific protection needs. they all emit powerful corrosion inhibiting molecules into an enclosure that settle on metal surfaces and protect them from corrosion.
Use Zerust diffusers to protect ferrous and non-ferrous metal such as iron, steel, copper, zinc, and solder. Their ferrous metal corrosion protection exceeds test requirements of all relevant standards including NACE TM0208-0208 and MIL-STD 3010A (test method 4031).
How the Zerust protective molecules suppress corrosion
- They passivate the electron flow between the anodic and cathodic areas on the metal surfaces.
- They may also form a hydrophobic layer that prevents water and moisture from direct contact with the metal therefore acting as an electrolyte.
- They may regulate the pH value of the electrolyte.
How to Install
- Remove product from packaging.
- Mark or take note of the installation date. Diffusers are conservatively rated for a wide range of environments to provide a minimum 1 or 2 year life depending on the model.
- Place the diffuser in the most ideal location possible following the principles below.
- Ensure that the airflow to the enclosure is restricted.
NOTE: Upon removal of the Zerust diffuser or opening the enclosure; the Zerust protective molecules will dissipate from the metal surface within hours. Corrosion protection of the metal surface will also cease by this time.
How to correctly place Zerust Diffusers
Center - the ideal location to obtain maximum coverage of protection from the capsule. This position may not be possible if the center is occupied.
Corner - In deeper enclosures two capsules may be required on diagonally opposed corners to fully protect the entire space.
Sides - Is practical for most applications and provides the optimum side mounted protection.
Dual Placement - For longer boxes or divided spaces, place a capsule in opposite corners for complete coverage.
It is essential to restrict airflow to the container. Airflow removes protective vapor barrier from the space faster than it can be released from the diffuser.
