Everyone who´ve ever seen an electric device working for several years outdoor knows, how atmospheric influence can testify on a plated copper board, connection, components, … This also happens on devices, which are seemingly “well protected” by a shelter, or placed in a building, but without heating and often also without a sufficient ventilation. High humidity (often even condensing) and temperature changes between day and night (causing humidity condensing in closed areas) are big enemies of a reliable operation of electronics. From this point of view, the most efficient and at the same time the cheapest solution is to treat PCBs, coils, transformers and other components by a suitable protective treatment.
In our offer 2 types of high-quality protective lacquers - Plastik 70 and Urethan 71 can be found. Plastik 70 was introduced to you in our recent article: With the 1 liter package of Plastik 70 you can protect your PCBs 50 % cheaper. It is suitable for practically all kinds of electronics and provides an advantage of fast drying and a relatively easy resoldering in case of necessity - at servicing and similar.
On the other hand Urethan 71, which we want to introduce to you this time, is chemically different, with properties of thermosets (maintains its strength even at higher temperature) with an excellent combination of hardness, elasticity and strong adhesion. Urethan 71 is highly resistant to moisture and to atmospheric influences, and represents a top choice for protection from humidity and corrosive atmosphere. Urethan 71 also fixates fixates small components as well as leads (for example coils, transformers, motors), that´s why it´s suitable also as a protection from vibrations. Moreover, this material features a low dielectric constant and low losses, thus being suitable also for high-frequency circuits. At latest, you can find in our store except the 200ml spray, also a cost-effective 1-liter package, with a higher yield.
Detailed information will provide you the Urethan 71 datasheet.
