Product description: High-value LED light components need excellent waterproof and breathable effects, so as to protect sensitive electronic components, prevent water and dirt from entering, and avoid car owners from complaining about "fog" or "dusting" on the headlights. LED lights are very susceptible to these problems, as the electronic components at the rear of them generate heat, which creates a cold spot in front of the lens. As long as a little moisture penetrates the case-even a few drops-it will condense at this cold spot, shielding the inside of the lens. The sharpness of the lenses of the current precision LED headlights makes the condensation and the particles they carry extremely obvious. Adhesive automotive waterproof and breathable products can solve this problem. Its proprietary microporous membrane allows air and gas to pass freely, so moisture can diffuse away before condensation problems can occur. Because the pores of this breathable membrane are 20,000 times smaller than water droplets, it prevents liquids and fine dust and particles from entering. Adhesive waterproof and breathable products have been put into use on global automotive platforms because they have the following advantages: No matter whether the car is driving or parking, it can quickly and continuously balance pressure and adapt to environmental changes. Effectively diffuses water and solves the problem of lens condensation. Effectively blocks dust, dirt, road debris, splashes and sprayed water, preventing them from entering the enclosure. With multiple performance options to choose from, the versatile solution is suitable for all lamp types (LED, Xenon and Halogen), as well as transparent and colored lenses. It can be safely and permanently bonded to common metal and plastic shell materials.
