Humiseal moisture-proof insulation covering glue 1B73 annual hot sale authentic products

Moisture-proof insulating coating glue is the best-selling authentic product of the year
Moisture-proof insulating coating glue Moisture-proof insulating glue is mainly used for coating air on printed circuit boards and components. It is the most common and most cutting-resistant machine board. Excessive moisture will significantly reduce the insulation resistance between conductors, accelerate high-speed decomposition, reduce value and corrode conductors. In such an environment that is unfavorable to the machine board, your machine board needs a piece of clothing to protect it. Reduce the degradation of electronic operating performance to a minimum, extend the service life of the machine board, and achieve the purpose of coating. The purpose of coating the protective film on printed circuit boards and components is to protect them when they may be affected by adverse factors in the operating environment. This can reduce electronic operating performance degradation to a minimum or eliminate it.
No covering glue can completely resist the adverse effects of the surroundings. Most of the adverse effects are cumulative and will eventually render the protective effect of the covering glue ineffective. If the coating glue can maintain its effect for a satisfactory period of time, it can be regarded as having achieved its coating purpose. Moisture is the most common and destructive environmental adverse effect. Excessive moisture will significantly reduce the insulation resistance between conductors, accelerate high-speed decomposition, reduce value, and corrode conductors. Hundreds of contaminants that can be found randomly on printed circuit boards are equally damaging.
They can cause the same results as moisture corrosion, causing electronic decay, corroding conductors and even causing irreparable short circuits. The most common contaminants found in electrical systems may be chemicals left over from the manufacturing process. Examples of these contaminants include fluxes, solvent release agents, metal particles and marking inks.
One major group of contaminants is caused by careless human handling, such as human body oils, fingerprints, cosmetics and food residues. There are also many pollutants in the operating environment, such as salt spray, sand, fuel, acid, and other corrosive vapors and mold.
Although there are countless pollutants, it is comforting to know that in most cases of serious pollution, good covering can effectively prevent them.
Coating is rarely exceeded. This coating can withstand mechanical vibration and swing, thermal shock, and operation at high temperatures. However,
The concept that films can be used to provide mechanical strength or sufficient insulation to individual parts inserted into a printed circuit board is wrong. Components must be mechanically inserted and require their own suitable caulking.
