Epoxy Zinc Rich Primer

Zinc Rich Epoxy (EZPTM code) is a two-component enriched epoxy primer that protects corrosion of the substrate and steel surface both during maintenance and during the new construction phase. As a high-performance anti-corrosion primer, zinc-rich epoxy or zinc-enriched epoxy primer provides the highest protection as part of the coating system for corrosive environments including offshore structures, petrochemical equipment, bridges and power station on steel surfaces. It also has anti-corrosion coating of reinforcements and rebars.


PRODUCT DESCRIPTION

What is Zinc Rich Epoxy and why is it called that?

Zinc Rich Epoxy is a type of protective primer for steel surfaces. Applying Zinc Rich Epoxy paint on steel surfaces creates a protective coating against rust as well as corrosion. Zinc Rich Epoxy Anti-Corrosion Product is a type of two-component zinc Rich Epoxy Primer. Zinc Rich Two-component epoxy paint has polyamide hardeners. In addition, zinc-rich epoxy primer is enriched with zinc metal. Because of these compounds, it is also known as Zinc Rich Epoxy Polyamide Primer.

What is the performance of Zinc Rich Epoxy in the structure?

Unlike conventional paints or epoxies, which resist corrosion by forming an impermeable layer between metal and air, zinc-rich epoxy primers provide corrosion protection by the electrolyte process. But what is the mechanism of Zinc Rich Epoxy Primer against corrosion? Instead of corroding the steel surface, at the end of the product, the corrosion process of zinc oxide will be in the form of a powder that remains from the zinc coating and acts as a protective coating for the steel; This greatly increases the service life of steel surfaces.

Why is it so important to maintain surfaces against moisture and corrosion?

If companies can invest in high quality coatings, they can save and reduce between 25 – 30 percent of their annual corrosion costs. Without proper coating, corrosion can have devastating effects on valves, motors, clamps, pumps, switches, belts, and other mechanical equipment.

The annual direct cost of infrastructure is about $ 22.6 billion. Corrosion costs a total of $ 47.9 billion annually for facilities such as water, electricity and gas.

  • Applying existing corrosion protection knowledge such as coatings can prevent and reduce up to 25% of corrosion costs.
  • Reduction of accidents: The risk of accident will be significantly reduced if the structures are free of corrosion. Work-related accidents cost $ 250 billion annually, many of which result from defective work equipment.
  • Save time: When the equipment does not function properly due to corrosion, it is a waste of time because after stopping the operation, delay in the production process will mean a loss.

How to use Zinc Rich Epoxy Primer

Surfaces to be primed should be cleaned and sandblasted. Surface defects must be carefully noted and corrected. The primer should be mixed in two containers according to the instructions in the technical data sheet of the coating and a uniform content should be obtained.

This coating can be applied with a brush, airless spray or air spray. For airless spray, the fluid pressure at the spray tip must be maintained in accordance with the coating manufacturer’s specifications. In the case of brush use, the recommended membrane thickness should be maintained (typical figures are 50- 75 microns per layer). The thickness of the selected membrane should correspond to the technical specifications of the surface.

Tips on Zinc Rich Epoxy

It is interesting to know that zinc-rich epoxy primer contains 90% zinc metal in dry state. Zinc-rich polyamide epoxy primer can be used both in construction and in maintenance of structures. Zinc Rich or zinc-rich epoxy paint is mostly used in structures that are exposed to corrosion and rust, such as marine structures, petrochemical equipment, bridges, power plants, etc. Zinc Rich Epoxies have a wide variety of colors. Zinc Rich Epoxy Primer can be white, blue, yellow, gray, orange, and so on. In addition to protecting steel surfaces, this product also gives decorative effects to surfaces due to their color. For this purpose, Zinc Rich Epoxy is also known in the market as Zinc Rich Paint.

Types of Zinc Rich Epoxy

Organic Zinc Rich Epoxy

 In this category of zinc-rich epoxies, organic zinc metal is used for enrichment. In this type of zinc-based paints and coatings, resins such as epoxy, butyl and urethane are used. This type of coating is easier to apply than non-organic coatings. They also provide good coverage. These coatings are usually designed to contain 75% or more of zinc in the dry state. Hardeners in this type of coating surround zinc more than inorganic coatings. For this reason, the protection of organic coatings against corrosion is less than non-organic coatings. These types of coatings are often used to repair (non-organic) mineral coatings. Organic coatings are less resistant to heat and abrasion than inorganic coatings.

Inorganic Zinc Rich Epoxy

 In this category, mineral zinc is used for mineral enrichment. In this type of coatings, silicate adhesives are used. Inorganic coatings offer better corrosion protection than organic coatings. These types of coatings require very clean surfaces to apply. Good mechanical properties, high impact resistance and high resistance to scratches and abrasion are the characteristics of inorganic zinc-rich coating. Also, this type of coating has a good heat resistance up to a temperature of 400 degrees Celsius.

Epoxy primer protection mechanism

Initially, when the Zinc Rich epoxy primer and its top coat (such as FRP fabrics) are applied as a continuous layer on the substrate, the system will act as a shield against corrosive environments and can be used as a protective coating. The bed cover completely separates from the environment. If the protective function of Zinc Rich Epoxy Primer is to be considered, its mechanism must be fully understood.

As mentioned, the epoxy primer and the coating on it completely insulate and protect the substrate, but if this coating is defective and the substrate is exposed to corrosive environment, the Zinc Rich epoxy primer layer is applied to prevent corrosion, causes reactions (by sacrificial anodes) with corrosive substances to delay the onset of electrochemical reaction (corrosion) of the substrate. The amount of metal protection that is created depends on variables such as the purity of the primer, the presence of moisture, and the electrical conductivity between the substrate and the zinc particles. In fact, in an anode primer, the zinc used in it acts as a cathode on metal surfaces, and when the zinc particles are converted to a zinc oxide reaction, the metal protection is complete.

The price of per kilo of Zinc Rich paint and the average annual growth rate of its investment

The market for corrosion-resistant coatings is projected to increase from $ 6.9 billion in 2020 to $ 8.9 billion by 2025. The average annual investment growth rate of this primer between 2020 and 2025 was 5.3%.

Based on the application of zinc-rich epoxy paint and its type, it is expected that their consumer market will be different. Epoxy primer is widely used in corrosion protection coatings. This is due to its excellent adhesion, corrosion protection and chemical resistance properties of epoxy primer. The strength properties of epoxy based coatings can be enhanced by the appropriate addition of additives and modifiers to meet the required specifications.

Zinc Rich Epoxy Primer is suitable for industrial, coastal, marine and freshwater environments. Commonly used for offshore platforms, stairs, refineries, steel tanks and petrochemicals and power plants, railways and other applications (pulp and paper mills, etc.). One of the key factors in the growth and development of this market is the expansion of the oil and gas market. Accordingly, the increasing use of epoxy primer as a protective coating is also expected to meet the demand created in the steel tank industry.

We hope that the global primer market will see a high growth in the production of epoxy primers and its increasing supply will lead to a reduction in the price of epoxy primers and improvements in the useful life of equipment.

The global market for Zinc Rich Organic Epoxy Primer was valued at $ 1 million in 2020 and is expected to reach $ 1 million by the end of 2027 and grow with CAGR (average annual investment growth rate) by 2021-2027.

Does the primer stop rusting?

The term rust inhibitor is commonly used to describe primers that contain zinc or zinc phosphate. Forms a rich primer on a sacrificial layer on a metal substrate. Zinc is more reactive than iron and in the presence of moisture, zinc oxide forms a sacrifice and prevents moisture and air from reaching the metal below.
