Does the circuit board conformal coating smell big?

Conformal coating, also known as circuit board conformal coating, three anti-glue, insulating paint, coating glue, coating glue, moisture-proof oil, generic film coating, coating coating, electronic coating materials, etc., is an English name of conformal coating.Conformal coating is a single component of room temperature curing, heating curing, UV curing transparent or translucent adhesives, with low viscosity, high transparency, excellent insulation performance, high and low temperature resistance, easy to use and so on.Conformation coating is mainly used in the assembly of all kinds of electronic circuit boards, PCB circuit board surface coating, coating role, to provide protection for the circuit board, so that the circuit board to moisture-proof, anti-fouling, anti-salt spray, insulation and other protection, in order to improve the performance of the product, stability, safety and service life.


The smell of the conformal coating mainly comes from the inside of the conformal coating solvent and body material, the smell of solvent has accounted for the proportion of larger, conformal coating need all volatile solvent in the drying process, no volatile solvent paint film is not dry enough, but the conformal coating is fully cured without smell, so in the use of anti-corrosion paint required under the environment of ventilation,The solvent evaporates and promotes the curing of the conformal coating.In the purchase of conformal coating if you need a smaller smell of conformal coating to choose less solvent content or solvent free conformal coating, such a conformal coating smell will be smaller, absolutely tasteless conformal coating is not.The above is the analysis of the odor of the conformal coating made by Yao Neng Company. I hope to give you some help when choosing and using the conformal coating.
