  1. Need To Know About Parylene Coatings – Uses and Benefits of Parylene Coating

  2. Gone are the days of using liquid conformal coatings for electronic, medical, military, aerospace, and automotive components. Parylene, a green polymer that does not need any initiator or chemicals to terminate the chain for its polymerization, is the new way of coating on plastic and other components. Also, many sectors worldwide use parylene coatings that are easy to apply with no solvent, even at near room temperature. Paryleneis the generic name for many members with different chemical structures and degrees of dielectric strength, low permeability biocompatibility, and moisture resistance of unique polymer series. This article will discuss all parylene coating, its uses, and benefits in many sectors to save a lot of costs, effort, time, and even lives coating medical components like stents and others.

  3. What is parylene coating? Before knowing what parylene coating is, it is essential to know what parylene is. It is the common name for many polymers with the backbone of para-benzenediol rings, of which functional groups replace some hydrogen atoms. Parylene coatings are the best alternative to chemical conformal coatings for protecting finished products from environmental hazards. The products may range from buttons to electric circuit boards to medical catheters to life-saving stents. The coating is difficult to find as the parylene condenses to form ultra-thin lightweight film less than 1 µm. It penetrates the product’s microporosity to provide pinhole-free protection and also lubricity. Parylene coating is better than liquid conformal coatings with little surface tension to avoid runoff or puddling. It provides many benefits for products used in many sectors worldwide for protecting products from many natural and artificial hazards.

  4. What are the types of parylene coating? • Depending on the parylene hydrogen atom replacement by functional groups, there are variations in parylene coatings. For commercial, these variations get denoted by letter and number codes registered as a trademark in many countries. A few of the types include. • ParyleneN has a linear structured crystalline material with each of its molecules having a carbon-hydrogen combination with high dielectric strength, low dissipation factor, and high aperture penetrating ability only next to Parylene HT. • ParyleneC has a chlorine atom replacing one hydrogen atom with each molecule to be high moisture and corrosive resistant • ParyleneD replaces two hydrogen atoms with two chlorine atoms to withstand temperatures up to 125 degrees Celsius

  5. ParyleneHT replaces the primary hydrogen atom with a fluorine atom to withstand temperatures up to 350 degrees Celsius and, with its small molecule size, gives the strongest parylene coating to be UV stable as it reaches all the nooks and corners of the product surface. • What are the uses and benefits of parylene coating? • There are many benefits of parylene coating, like being pinhole-free, offering uniform thickness, salt spray resistance, thin film dielectric, and a superior moisture barrier that is conformal truly. It helps the coated components from many harmful environmental factors like dust, chemicals, salt, moisture, chemicals, mechanical abrasion, corroding, and mechanical abrasion. For the past four decades, it has been protecting and lubricating metals, plastics, electronics, and elastomers. It helps to ruggedize many electronic, medical, military, aerospace, and automotive products. The ultra-thin coating is ideal for all crevices, shapes, and edges and with any effect of the conventional coating methods. • The above facts, types, and uses will convince anyone to use parylene coating from equipment made by the best and most experienced manufacturer for availing of all its benefits.

  6. It is important to have a budget for your product and its coating. Good industrial coatings can be expensive and capping on your maximum spending can lower your costs. • Research on your available choices; seek help from professional organisations, consultants, etc. to determine the best coating for your product. • Always opt for certified suppliers. Similarly, look for the offerings from the same to determine new advancements and alternatives that suit your business. • An eco-friendly supplier ensures that their coating is compliant with the latest norms and suitable for use minus any hazards.
