Zinc Flake Coating and Geomet500: An Ultimate Guide
Zinc flake coatings are considered a combination of flakes of zinc and aluminium. This combination of flakes is suspended in a binder or resin matrix. The flakes form a layered structure on the surface that creates a barrier shielding the metal from environmental factors. Environmental factors include moisture, salt spray, and chemicals.
Use of the Zinc flake coatings:
Generally, zinc flake coatings are applied using a spray or dip process and are cured through heat or air drying. These can also be used as standalone coatings or as a part of a multilayer coating system that serves as the base layer for additional paint or powder coatings.
Geomet is a coating film that has a silver-metallic look. The layers of metal flakes are connected through the special inorganic binder. This film is extremely thin and is only about 8um-it, which will not negatively affect the optimal fit between bolts and nuts. There are three types of Geomet, namely Geomet 720, Geomet 321, Geomet 500, and Zincrokote. You can count on our expertise to meet all your coating requirements with our quality service.
Geomet720:
Geoment720 combines with a wide range of topcoats that pass through mostly the severe cyclic tests. This helps protect the parts from getting rust even after the mechanical damage. Mechanical damage might include stone chipping, but the Geomet 720's self-heating property has it all.
This also ensures bimetallic compatibility with the aluminium alloys. We have come up with effective coating solutions. Try out our service.
Some of the other features of the Geomet coatings are as follows:
Temperature resistance: The temperature resistance property is maintained up to 350 degrees Celsius.
Static friction: Static friction coefficient is larger than 0.20.
Electrical properties and characteristics: Electrical properties include the conductive feature, which offers perfect galvanic properties. This helps in avoiding bimetallic corrosion in most industrial assemblies. The materials include cast iron, carbon steel, and aluminium alloys.
Tolerability: Provides an excellent surface solution for paints or additional coatings.
No hydrogen embrittlement: This process is implemented via non-electrolytic application processes. This helps avoid the hydrogen embrittlement phenomenon that causes metals to crack.

The process of coating:
Several steps are included in the coating process that are as follows:
Degreasing or drying- The removal of soil from the parts of materials that may have some oils while processing is necessary.
Shot blasting- The purpose of blasting is to expose fresh metal surfaces of femora that are inorganic, such as rust and scale, from the surface of the part by mechanical force. To ensure enough sacrificial protection, it is necessary to make good contact between the zinc and steel surfaces; for example, the scale could interfere with the flow of the electric current.
Coating process- The purpose of this process is to apply enough zinc and aluminium flake paint uniformly on the parts' surface.
The processes are largely classified into the following types: Spray method and Dip spin method.
Curing process- Geomet's curing process consists of two stages. Vaporising water and organic solvent and following film form reaction.
Final inspection- In this stage, 100% inspection takes place for coating defects. The approved material is packaged and dispatched.
Testing facilities- Salt spray testing is a laboratory simulation of a corrosive saline environment. This is an accelerated form of testing that can withstand atmospheric corrosion. Also known as salt fog testing.
Zintek, which is a deep black zinc flake surface base, has a deep black appearance and provides corrosion protection and delayed white corrosion formation.
Zinc flake coatings are made of a mixture of zinc and aluminium flakes that are bonded together by an inorganic matrix.
They are applied non-electrolytically and provide cathodic protection, where the zinc corrodes itself to protect the underlying metal.
This type of coating can be used on a variety of base materials, including steel, aluminium alloys, stainless steel, and die-cast zinc.
It's also ideal for components that need to fit accurately, like screws with metric threads.
Conclusion:
The zinc flake coating thickness is about 12-15 microns. Discover and explore a wide range of services with Aum Dacro Coatings.
