Car lights are essential components of automobiles, playing an important role in night lighting, driving signals, fog anti-collision, steering signs, and other aspects, and providing an important guarantee for safe driving of automobiles. In the production of automotive lamps, in order to seal the lens and lamp housing, sealant must be used for bonding.

In the application of lamp adhesive, first of all, the lamp sealant must be affected by the heat emitted by the bulb. Under corresponding high-temperature environments, it must be ensured that its adhesive and sealing properties do not change, and at the same time, it cannot release organic gases, produce atomization, and do not turn yellow, affecting the appearance.

Secondly, when the vehicle lamp sealant is exposed to ultraviolet radiation in the sun, it will not undergo aging phenomena such as cracking of the adhesive layer, which requires that the vehicle lamp sealant should have good ultraviolet aging resistance; Finally, the lamp sealant will also be subject to long-term erosion by water vapor and rain, so it is necessary to ensure that its sealing performance will not be affected by this.

Due to its unique molecular structure, excellent adhesion, high and low temperature resistance, excellent weather resistance, good hydrophobicity, excellent electrical performance, and chemical corrosion resistance, silicone sealant products are widely used in vehicle lamp sealing.
