Benefits of Parylene Coating

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 doesn’t 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.
