How to Properly Select Zinc-Rich Coatings

In modern industry, corrosion protection is a critical aspect of ensuring the safety of equipment and structures. Zinc-rich coatings are highly favored for their exceptional anti-corrosion performance.

With a wide variety of zinc-rich coatings available, choosing the right product has become a significant challenge for users.

This article introduces the features, application scopes, and selection methods of Jino Shengcheng's Epoxy Zinc-Rich Paint、Inorganic Zinc-Rich Paint and Cold Spray Zinc Paint to help you make a more informed decision.

一、What Are Zinc-Rich Coatings?

Zinc-rich coatings are a type of anti-corrosion paint containing a high concentration of zinc powder, primarily used for protecting steel structures. The zinc powder in the coating provides cathodic protection, meaning that when the coating is damaged, the zinc particles corrode first, thereby protecting the underlying substrate from corrosion.

二、Introduction to Epoxy Zinc-Rich Primer

Jino Shengcheng's Epoxy Zinc-Rich Primer is a high-performance anti-corrosion coating containing up to 80% zinc powder. It provides robust electrochemical cathodic protection, effectively blocking corrosion.

  Product Features

       - Electrochemical Protection: High zinc content in the film offers strong electrochemical cathodic protection.

       - Excellent Corrosion Resistance: Outstanding resistance to acids, alkalis, salt spray, seawater, and atmospheric conditions.

       - Strong Adhesion: Bonds well to metal substrates, forming a dense coating that resists peeling.

       - Easy Application: Can be applied by brushing, rolling, or spraying. It is environmentally friendly and non-toxic.

  Scope of application

Suitable for corrosion protection in various steel structures, such as bridge engineering, power facilities, petrochemical equipment, shipbuilding industries, steel structure buildings, and pipeline storage.

三、Introduction to Inorganic Zinc-Rich Paint Products

Jino Shengcheng's Inorganic Zinc-Rich Paint uses ethyl silicate as the base material and contains up to 80% zinc. It can withstand high temperatures up to 400°C, making it suitable for high-temperature environments.

  Product Features

       - High-Temperature Resistance: Can endure temperatures up to 400°C.

       - Strong anti-corrosion performance: Provides cathodic protection and is suitable for workshop pre-treatment of steel structures.

       - Excellent Mechanical Properties: The paint film has superior mechanical strength, making it resistant to handling, friction, and impact.

       - Easy Application: Suitable for automated production line spraying.

  Scope of application

 Suitable for corrosion protection in various steel structures, such as bridge engineering, chemical equipment, steel structure buildings, ship docks, oil and gas storage tanks, and workshop pre-coating.

四、Cold Spray Zinc Paint

Jino Shengcheng's Cold Spray Zinc Paint is a single-component, high-zinc-content coating with a zinc content of no less than 96%. It is made from conductive organic resin and high-purity ultra-fine zinc powder.

  Product Features

       - High Zinc Content: Dry film zinc content reaches 96%, providing triple protection: electrochemical anti-corrosion, barrier protection, and corrosion inhibition.

       - Weld Resistance: Welding over the coating does not affect welding quality, and the coating remains undamaged by cutting or welding.

       - Salt Spray Resistance: Can withstand up to 3000 hours of salt spray testing with excellent film performance.

       - Low-Temperature Resistance: Can endure temperatures as low as -60°C.

       - Easy Application: Single-component formulation; simply stir and apply by brushing or spraying.

       - Short Construction Period: As a cold galvanizing heavy-duty anti-corrosion coating, it can be applied in one day and reaches optimal performance within 4 days.

  Scope of application

Suitable for on-site cold zinc spraying as a corrosion-resistant primer for steel components, serving as an alternative to hot-dip galvanizing, thermal spraying, epoxy zinc-rich primer, and inorganic zinc-rich primer. It is also ideal for repairing galvanized or hot-dip galvanized anti-corrosion coatings. Widely used in fields such as bridges and power engineering.
