It is impossible to find one product on the market that will protect your metal parts in every situation. The science behind what causes the metal to corrode is the same information that will help you find the perfect way to protect.
Type of Metal and Existing State
The chemical composition of the metal used determines the susceptibility of the material to corrosion. In other words, some materials are weaker than others when exposed to basic elements. Water, acid, salts, and UV exposure can all lead to corrosion at different rates. The state of the metal also plays a role in the rate of corrosion. Metals that are treated will fend off corrosion for longer periods of time.
Environmental Factors and Corrosion
The environment that metals will be exposed to plays an important role in making the right decision for corrosion protection. Electrochemical processes cause the most breakdown and corrosion of metals in industry. The use of lead-free and chrome free anti corrosion liquid provides excellent protection from most environmental factors.
Pigment Solubility and Barrier Layer Protection
How well a liquid protective material covers the metal with pigment and the solubility levels determine the overall protective quality. Providing a strong barrier of protection will reduce incidences of corrosion wear.
How pH Levels and Environment Clash
The pH of the pigment used to protect against corrosion can have a great effect on the environment it is placed inside. High pH can impact an acid environment in a negative way. Low pH can negatively affect a waterborne environment. It is one element to keep in mind when making the perfect choice in corrosion protection pigment.
It would be nice to come up with a pigment that allowed for the complete protection of all metals in all circumstances. Unfortunately, this is not the case. You can find products that offer long-term protection for your exact needs for each individual circumstance.
