7 Ways To Protect Your Plated Parts from the Effects of Summer Humidity

When zinc plating is exposed to a combination of heat, humidity, and moisture- changes in color or corrosion can begin to occur. This is very common during the summer months when temperatures and humidity levels are high and constantly changing.

To protect the surface from red rust, Zinc Plating does what it was meant to do by sacrificing itself first, which shows as white flaking or powder on the surface of a part. This is the result of Zinc reacting to water and air in the environment and is the first indication that the protective finish is beginning to break down.

There are several things you can do to help ensure seasonal weather changes won’t compromise the plating on the surface of your parts.

For Best Results in Preserving Your Zinc Plated Finish:

1.)    Do not leave parts sealed up in crates or containers for long periods of time.

This increases the risk of long-term exposure to humidity and moisture that will degrade the finish. Adequate airflow is key to preventing corrosion during the summer months.

2.)    Minimize the amount of direct contact the finish has with foreign materials.

Paper, plastic, wood, cardboard, etc. can trap moisture leading to color change and corrosion.

3.)    Use Vapor Corrosion Inhibitor (VCI) packaging materials.

Materials such as VCI bags or VCI paper can help block moisture from a part’s surface.

4.)    Wear clean gloves when handling.

Avoid touching the plated finish with bare hands to prevent moisture and sweat from transferring onto your parts. 

5.)    Store finished product to allow adequate airflow around each part.

This will enable parts to dry if they are exposed to moisture. Leaving parts tightly packed and sealed in containers increases the risk of long-term exposure to humidity and moisture which degrades the plating.

6.)    Avoid storing products in an environment with large temperature variation.

Constant heating and cooling may cause condensation. Store parts in a temperature-controlled environment if possible. Utilizing a dehumidifier to control humidity levels can also help eliminate excess moisture from the air.

7.)     Don’t store parts near open doors, windows or louvres.

This can help minimize further exposure to humid air.
