Benefits of Parylene Coating
Parylene coating is a form of conformal coating
that is used to improve the capabilities of
leading-edge technology. It is a thin film of
coating that is applied as a vapor and helps to
conform to the shape and design of your products
with ease. As a result, the same provides better
coverage and outcomes that can be indispensable
when it comes to making a waterproof coating on
the circuit boards.

There are numerous benefits of opting for
the Parylene Coating Process for your products
These Offer Excellent Surface Protection A
large number of manufacturers choose to invest in
Parylene Coating in Malaysia as it provides
unmatched performance, especially in terms of
-          Thermal protection -         
Chemical safety -          Moisture resistant - 
        Environment barriers, etc.

This makes it an excellent choice for rugged use
despite its micro-level thinness.         It
is a True Conformal Coating The gaseous nature of
the deposition process makes the surface even
especially if your product has sharp points, deep
cervices, and an irregular shape. Parylene
doesnt pull away from the edges and thus you
attain a pinhole-free application.   Room
Temperature Deposition Parylene can be used on a
range of materials especially the ones with
delicate substrates which makes it a highly
effective option without adding any weight and
mass.

•   It has a Low Dielectric Constant
• Parylene has a low dielectric constant that
  enhances signal processing speeds especially due
  to its moisture barrier characteristics.
• It helps to Achieve a Stress-Free Application
• Parylene polymerization occurs at room
  temperature which protects the circuit boards and
  similar devices from thermal stress. The film
  does not cure in the conventional sense and this
  has no mechanical or temperature stresses on the
  fragile components.
• Dry-Film Lubricity
• Parylene film has a low static and dynamic
  coefficient of friction. This can be a valuable
  coating, especially for applications where there
  is an issue associated with stickiness.

• It offers Amazing Optical Clarity
• The transparency and clarity of the film are
  unmatched. It helps to bring awesome benefits in
  terms of quality management and assurance.  Since
  the same has non-absorption of the visible light,
  this makes it suitable for optical use.
• It has a Superior Electrical Insulation
• Parylene also has superior dialectical properties
  with a strength greater than 5000 volts per mil,
  which makes it perfect for insulating electronics
  and has minimal dimensional change.
• These are applied at an ambient temperature along
  with a specialized vacuum deposition method.  The
  process occurs at a molecular level where films
  grow a molecule at a time

• A granular material called dimer is heated under
  a vacuum and then vaporized into a dimeric gas.
• The gas is then used to cleave dimer into
  monomeric form.
• At room temperature, the monomer gas deposits on
  all surfaces as a thin and transparent polymer
  film.
