Specialty Coating Systems (SCS) elaborates on the significance of conformal coatingsas essential moisture barriers for electronic devices, detailing various types, advantages, and applications.
In our modern, tech-centric society, moisture exposure remains a primary threat to the functionality of electronic devices.
When moisture infiltrates the circuitry of electronic devices, it can lead to short circuits and subsequent failures. Environments characterized by condensation within enclosures, corrosive humidity typical of coastal areas, rainfall, and direct water exposure present notable challenges for safeguarding electronic applications.
To combat these issues, engineers often aim for ingress protection ratings ranging from IPX4 to IPX8. Conformal coatings are widely recognized for their ability to serve as effective moisture barriers, helping products achieve these critical IPX ratings. Various types of coatings, including acrylic, epoxy, polyurethane, silicone, Parylene, and plasma coatings, offer diverse moisture protection properties for electronic and electrical components.
when evaluating conformal coatings,it is essential to consider the required level of protection,design factors,and the long-term operational environment. Parylene coatings, as an example, are especially effective against moisture ingress and play a vital role in attaining IPX7 and IPX8 ratings. Additionally, the innovative SCS PlasmaGuard coatings have been rigorously tested to meet the demands of IPX7 and IPX8 specifications. Liquid silicone coatings also provide robust moisture barrier capabilities,making them suitable for applications like refrigeration units where condensation is a concern.
No matter the intended use of an electronic device, moisture is a common factor in many operational settings. Conformal coatings are specifically engineered to guard against varying levels of moisture, making them a crucial element in achieving desired IPX ratings.
