Understanding the Parylene Coating Process

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.

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