54 DESIGN007 MAGAZINE I MARCH 2021 a two-part 2K coatings range, which provides more resin-like protection, with the applica- tion ease of a coating. is has been a great success with applications in aerospace and automotive, where protection in harsh envi- ronments is absolutely critical, whilst mini- mising the increase in product weight. I will be exploring coatings vs. resins in a little more detail, using my usual five-point Q&A format. 1. What are the main differences between resins and coatings? e first difference between resins and coat- ings regards the various methods of applica- tion. For instance, there are aerosols, confor- mal coating spray equipment, manual spray guns, and brushing for coatings, compared to mixing and dispensing equipment, and resin is month, I examine some of the key dif- ferences between conformal coatings, encap- sulation resins, and potting compounds to help designers make more informed decisions, and ultimately help increase the performance, reli- ability and lifetime of your electronic circuitry. I also look at issues that some of you may have with mixing resin packs and air bubbles, what can go wrong and why. No one wants a product recall, or worse still, a product failure. erefore, protecting cir- cuitry for its intended purpose and end-use environment is imperative to extend product lifetime and maintain your brand's reputation. Resins are an excellent way of protecting electronic circuitry, however, there are some excellent conformal coating alternatives on the market as well. For instance, we have created The Role of Resins and Conformal Coatings Sensible Design by Phil Kinner, ELECTROLUBE
