What type of primer is Zinc Molybdate classified as?

Zinc Molybdate is classified as an anti-corrosive primer due to its specific properties and intended use in preventing corrosion on metal surfaces. This type of primer contains zinc, which acts as a sacrificial anode, offering protection by electrolytically facilitating the oxidation process away from the underlying metal. The addition of molybdate enhances its effectiveness against corrosion, particularly when exposed to harsh environments.

The formulation of Zinc Molybdate not only helps in preventing rust and corrosion on ferrous surfaces but also provides an additional level of durability and resistance, making it suitable for marine and industrial applications. Its primary purpose is to protect the base material from moisture and corrosive agents, which is essential for maintaining the longevity and structural integrity of coated surfaces.

In contrast, non-skid primers are designed to provide traction, water-based primers are typically formulated for easier application and cleanup with water as a solvent, and high-temperature primers are specifically created to withstand elevated temperatures. Thus, the designation of Zinc Molybdate as an anti-corrosive primer aligns precisely with its functional attributes and application scenarios in protective coatings.
