Choose the Right Automotive Lamp Glue to Ensure Your Driving Safety

As a very important component of a car, automotive lamps (car light) play an important role in day/night lighting, traffic signals, fog light collision avoidance, direction signs, etc., and are an important guarantee for the safe driving of cars.



In order to seal the mirror and the lamp housing, the lamp sealants must be used for lamination. At the same time, it is matched with UV Primer to fill the reflective surface, and Hard Coat is applied to the surface of the shell to increase weather resistance. All the adhesives must effectively resist high and low temperature, having resistance to UV and moisture, not yellow or foggy, also good adhesion to plastic.
 

Automotive Lamp Industry Trend

According to the report, the global automotive lighting market size was valued USD 27 billion in 2020, and is projected to reach USD34.9 billion by 2025, at a Compound Annual Growth Rate of 5.3% during the forecast period. An increase in premium and SUV sales and advancements in lighting technology are some of the major factors driving the growth of the automotive lighting industry.

However, due to the Covid-19 pandemic, there is a chips supply crisis, which also cause an influence on car lighting industry. Fortunately, demand for automobile picked up again at the end of 2020, although chip supply issue will not be resolve in a short period of time, car lamp will always be needed.

Bullet Points for Adhesive Choosing

• High and Low Temperature Circulation Resistance：The light bulb will emit heat when used for a long time. In such a high temperature environment, the car light glue needs to maintain its adhesion and sealing; and when the car is not running, the car light glue temperature will slowly drop. Outdoor temperature, it is necessary to ensure that the colloid will not delaminate or crack at low temperature, and maintain excellent flexibility.
• UV Resistance：Cars parked on the side of the road will be exposed to the sun for a long time. The car lamp glue must have the characteristics of not cracking, not aging and maintaining the sealing effect.
• Moisture Resistance：The car will also be corroded by water vapor and rain for a long time. The headlight glue needs to ensure that its tightness will not allow moisture to enter the interior of the headlight.
• No Yellowing and No Fogging：The car lamp glue cannot release organic gas to cause the fogging of the car lamp. At the same time, make sure that the light glue does not deteriorate or yellow to maintain the appearance of the light.
• Good Adhesion to Plastics：Considering the weight and cost, most of the current car lamp housing materials are composed of ABS, PC, PP and other plastics. Choose an adhesive that has good adhesion to plastics.

Types of Automotive Lamp Adhesives

• Butyl Rubber Based HMA：Good adhesion to general engineering plastic materials and glass, and excellent high temperature resistance, low temperature resistance and heat aging resistance.
• Gel-Like Sealant HMA：No pollution, low molecular weight, no atomization, good high and low temperature resistance. No wire drawing during dispensing, excellent sealing, waterproof, anti-air leakage, light leakage and caulking effect. Removable and separate lamp lens and lampshade, recycling, rework and reuse. 
• PUR Based HMA：The adhesion is high, the response speed is fast, the initial solid force can be quickly generated, and the PUR glue machine is used for a long time with less blockage.
• UV Primer：Good heat resistance and adhesion to plastic substrates. After UV curing, it can effectively fill the uneven surface.
• Hard-Coat：Suitable for PC substrate, excellent thermal shock properties, hardness and adhesion. After UV curing, it can effectively protect the shell from deterioration factors such as light, heat, oxygen, water, etc.
