Understanding the Parylene Coating Process

Deciding on the ideal coating for business applications is important. As a manufacturer, you are expected to assess and determine the mechanical and component compatibility.

Options like Parylene AF4 Polymer and similar Parylene alternatives offer superior barriers against moisture and corrosion without actually impacting the function of the same. The final coatings are uniform and thin in application.

Having the best Parylene Coating Manufacturers for your product can deliver significant advantages especially in terms of reliability and accuracy of the product. Further sensitive equipment can be coated using the method to attain effective results at all times. This results in better customer satisfaction and brand loyalty.

Parylene Coating Process

One of the major advantages of choosing Parylene or Nano Ceramic Coatings is that these are easy to apply. The vapor of Parylene can go under the crevices which makes it easy to coat semi-sealed areas.

Since the entire Parylene Coating Process is conformal, there is lower wastage and dripping. It is easy to get a uniform coating on uneven products.

Also, the entire Parylene Coating Process adopts vapour based deposition that makes it a desirable choice despite its high expense. Further the coating is applied at ambient temperatures using specialised equipment. The entire process takes place at molecular level through –A dimer which is a solid and granular raw material is heated up. The entire process is completed in vacuum to attain the gaseous.

Then pyrolysis is done to cleave the dimer into a monomeric form

At the room temperature, the gas deposits on all surfaces as a transparent film Since the entire process is undertaken in a gaseous phase, the coating deposits evenly on multi-layered equipment to get uniform encapsulation

Optimal thickness of these is determined on the basis of applications and desired outcomes. The same can range from angstrom to mils.

Variables influencing the Parylene Coating Process

 Choosing the right Parylene Coating Process increases its performance and durability. However the following factors can influence the final outcomes –

 Substrate materials



The optimal adhesion of Parylene is ideal for use across metals, plastics, glass, paper, etc. For best results, A-174 silane is used.



Substrate cleanliness

 To attain adequate outcomes, Parylene adhesion must be cleaned. Particulates, oils, etc. can contaminate the surface which ultimately impacts the coating performance, adhesion and outcomes.

penetration

One of the prime benefits of coating across surfaces is that the same is able to coat across multilayer and crevices with ease.

Coating Process  Using a highly trained staff and industrial applications, it is easy to get the best results. Hence having the right manufacturers to back your manufacturing processes is important.
