What are the characteristics of LED display potting glue? LCF leads everyone to learn together:


The LED display is a display carrier composed of a display of small lamp beads. It is often used in outdoor advertising displays, and is especially used in underwater or relatively humid environments.


LED displays have been exposed to harsh and harsh environments for a long time, and they must have good environmental adaptability. Therefore, it is necessary to use potting glue to provide sealing protection, insulation and waterproofing, so as to avoid long-term exposure of printed circuit boards and LED pins inside the LED display to harsh environments, so as to protect them from rain and ultraviolet rays. Environmental impacts of erosion, back to the city, wind and snow, etc. Another function of the LED potting glue is to fix the LED lamp beads, which greatly improves the resistance to external shocks and vibrations, and effectively prevents the LED lamps from skewing and causing defects in the quality of the display screen.

After understanding the characteristics of LED display potting glue, what should be paid attention to when purchasing?




1. The properties of elasticity, toughness, tensile force and adhesive force after curing of colloid


After the LED potting glue is potted, the potted product must be able to withstand various outdoor environmental tests. After a long-term test, it can maintain a very stable performance, and the shrinkage rate of the glue will not shrink with time. .




2. Weather resistance


The potting glue must withstand the long-term test of high and low temperature zones, wind and snow, rain, ultraviolet rays, etc., then its high and low temperature resistance range and radiation resistance should also be well selected.




3. Manufacturers


The performance of the potting compound is related to the selection of raw materials. Due to vicious competition in the market, some manufacturers use inferior and low-priced raw materials, coupled with immature technology, there may be potential quality and safety hazards after long-term use, such as: falling off, tortoise cracks, oil seepage, etc.
