Benefits of Parylene Coatings for Your Industry 

Industrial coatings are special layers of substances that when added to the surface provide better protection and enhance the overall appearance of the surface.

The primary function of choosing industrial products like Parylene Coatings is that it helps to protect the surfaces against elements and other forms of damage.

Similarly, conventional coatings are applied to a wide range of surfaces – 

  • Rubber
  • Concrete
  • Coatings on plastic 
  • Timber
  • Leather 
  • Glass
  • Mortar
  • Metal 
  • Asbestos, etc.

There are endless options available in the case of metal protection coatings,etc. and each offers a unique characteristic over the other. This type of environment and the nature of the surface can be coated effectively to determine the best solution for your requirements. 

Top coating suppliers offer suitable consultation and guidance to ensure that you make the right selection for your needs. This is especially useful for electronics coatings.

Reasons for choosing such Coatings

The purpose of choosing industrial coatings is to deliver protection to the product in its operating environment. Aesthetics are also important to ensure the overall appeal of equipment and supplies.

Similarly, these coatings are designed to improve the resistance of selected materials to fire and other hazards. These are also designed to offer specific protection and corrosion resistance.

The top considerations for choosing these coatings are –  

  • Substrate surface preparation 

To ensure effective results, the substrate or base materials must be clean. Most of these coatings use physical or mechanical bonds to stick tightly to the surface.

Chemical bonds with the surface can offer an impenetrable layer of protection. If the treatment surface is not clean then the desired results will not be achieved.

Hence, the surface must be cleaned of dirt, moisture and other contaminants. For this, techniques like heating, blasting, and chemical cleaners can be used.

This helps to ensure that the surfaces are free from fisheye, blisters, bubbles and adhesive failures.

  • Selecting the right coating system

Priming is important for coatings and sealant adhesion. This helps the products to adhere to the surface for long-lasting results.

When there are incompatible materials and coatings then primers help them to work together. This is also important to improve the overall appearance of the same by removing imperfections.

  • Coated joints 

Using primers helps to prepare the surface for the coating process. Each type of coating process and method has its advantages. These methods are crucial to coat the surface yet aspects like size and complexity of the surface, etc. are other vital factors that impact the final choice of coatings.

  • Curing and drying process

The performance of industrial coatings is influenced by the curing and drying processes. 

If the curing and drying procedures are inadequate then your product may not be able to perform effectively. 

Thus, consulting with the coatings providers helps to provide detailed information about the right drying method, curing process and procedures that help to deliver optimal results.

These coatings require the curing process to be done at optimal temperatures for a specific time. The temperature and specifications apply to the substrate and this results in variable timings for parts.

  • Parts inspection

Once the coating process is complete, the parts must be inspected to ensure that the coating is according to the desired parameters. Each coating delivers a specific thickness to the product and must adhere to the overall standards for the best results.

When choosing these coatings, the equipment, materials, etc. must be considered. With an optimal industry coating process, you will need pump seals, clean filters, etc.

Why choose parylene coatings for my product?

Parylene coatings have a wide range of applications yet these are more suited for those with sensitive circuits, applications, etc. These are hence designed for use in equipment for the aerospace industry, electronics, medical equipment, etc.

  • The application process 

The entire process involves applying vapour deposition of the coatings to attain a thin coating. This barrier protects the assembly from chemical contamination and moisture-associated damage.

  • Attaining adhesion 

To ensure an appropriate adhesion, the surface must be micro-cleaned using techniques like plasma surface modification. Once done, the coating is applied in thin layers using spray or flow techniques. 

  • Compliance standards 

Parylene can be applied to meet stringent FDA standards for medical devices. 

It also offers low friction and abrasion-free coating for magnets, seals, etc.

Types of parylene applications 

  1. Parylene C has the following applications –
  2. Provides a combination of physical properties.
  3. It has low moisture permeability.
  4. It offers resistance to chemicals and gases.
  5. Good electrical conductivity.
  • Parylene N has the following applications –
  • Apart from the comparable characteristics with Parylene C, it also offers results in extreme temperatures minus oxygen.
  • High dielectric constant.
  • A highly preferable dimer structure.
  • Parylene D has the following applications –
  • Additional chlorine atoms bring better thermal conductivity.
  • The dimer has the lowest conformal structure.
  • Parylene HT has the following applications –
  • Lowest coefficient of friction among all parylene types.
  • Uses alpha hydrogen atoms and fluorine.
  • Low dielectric constant.

Can conform to any surface due to low molecular size.
