Dymax 9452-FC from Intertronics is an electronics conformal coating formulated with a revolutionary new technology as an alternative to thin, solvent-based conformal coatings. Whilst it has a very low viscosity – 20 cP – it still provides good electrical insulation and protection against humidity, as well as, very good thermal shock and corrosion resistance. It offers an instant UV and visible light cure with secondary heat cure for shadow areas within electronic assemblies, to ensure that no area is left unprotected. It also fluoresces blue, which enables fast, easy inspection. It is believed to be the first light cure conformal coating to successfully provide these high performance characteristics in one easy to use product.
This coating can be precision sprayed. It is environmentally friendly compared to solvent-based alternatives, being 100 % solids. It is curable using UV LED-based curing systems, in addition to conventional broad spectrum lamps, with the associated production and cost benefits.
In-house analysis shows the coating‘s exceptional performance through reliability tests such as heat and humidity resistance (500 hours at 85 ° C / 85 % relative humidity) and corrosion resistance (sulphur and salt spray resistance).
