Faced with The "recall Controversy", Volvo Used A Tube of Glue To "stick" The Car's Safety Conscience.

Recently, Daqing Volvo Car Manufacturing Co., Ltd. announced a recall of some domestically produced S60 and S90 models produced between September and December 2024, involving a total of 12465 vehicles. The reason for the recall directly refers to the insufficient adhesion of the vehicle's glass adhesive due to material issues, which may pose a safety hazard of glass and body loosening.

Although this incident exposed the negligence in the production process, it further demonstrated Volvo's corporate attitude of "respecting life and being responsible to consumers" - from proactively identifying problems to quickly initiating recalls, and then to a commitment to free repairs, Volvo has demonstrated the brand value of "safety first" through action.

And this recall controversy has once again drawn public attention to a often overlooked "invisible component" in automotive manufacturing - glass glue.

PART-01

The "guardian" of automobile safety In automobile manufacturing, glass glue is not a simple adhesive, but a core component that carries the structural strength and passive safety of the vehicle body.

1. The "mechanical backbone" of structural strength. Modern cars adopt a load-bearing body design, with components such as the windshield and sunroof rigidly connected to the body through glass glue, forming an overall load-bearing structure. If the glass adhesive fails, the A-pillar and roof of the vehicle may deform due to uneven force, resulting in compression of the passenger compartment space.

2. Passive safety "life barrier" According to the IIHS (Insurance Institute for Highway Safety) testing standards, the tensile strength of car glass adhesive needs to reach 6 MPa or more (equivalent to bearing 60 kilograms of tension per square centimeter) to prevent passengers from being thrown out or suffering secondary injuries from glass splashes. The models recalled by Volvo this time are at risk of loosening precisely because the glass adhesive does not meet this standard.

PART-02

Volvo's "safety philosophy" in the face of glass glue issues, Volvo's response can be regarded as an industry model:

1. Proactively recall and face the problem. According to the "Regulations on the Management of Defective Automotive Product Recalls", Volvo immediately filed a recall plan with the State Administration for Market Regulation after discovering the problem, and promised to provide free inspection and re bonding of glass for the recalled vehicles. This measure not only reflects the importance attached to consumer safety, but also demonstrates the courage of enterprises to face problems directly.

2. Technical traceability and system repair: Volvo authorized dealers will use professional equipment to test the bonding quality between the glass and the body, and use factory certified glass adhesive for repair. Ensure that the repaired vehicle meets safety performance standards.

3. Transparent communication and trust building. Volvo notifies car owners through various channels such as registered mail and customer service hotline, and arranges for dealers to proactively contact for recall matters. This transparent communication method effectively alleviates consumers' concerns and maintains brand reputation.

PART-03

From a technical perspective, the "safety essence" of glass glue may be small, but it is related to all aspects of automotive safety:

1. Adhesive strength: 6MPa is the life line standard, which originates from the calculation of the impact force that glass needs to withstand in collision testing. If the tensile strength of the glass adhesive is insufficient, it may cause the glass to separate from the body, causing the passenger's head to directly hit the body frame.

2. Weather resistance: The "guardians" of extreme environments require cars to adapt to global extreme weather conditions. Volvo's original glass adhesive is made of silicone material, which can maintain stable performance within the range of -50 ℃ to 150 ℃.

3. Construction technology: Millimeter level accuracy determines success or failure. The bonding effect of glass adhesive depends on millimeter level accuracy

Adhesive layer thickness: The standard is 1.5-2.5mm. If it is too thin, it may lead to insufficient bonding, while if it is too thick, it may result in uneven curing.  

• Curing time: 24 hours for surface curing, 72 hours for complete curing. If not fully cured, driving on the road may cause glass vibration or even detachment.

PART-04

The recall incident of Volvo is not only a warning to the production process, but also an interpretation of brand responsibility. Although glass glue is small, it carries the heavy responsibility of vehicle structural safety and passenger life protection with a width of millimeters.

From the impact resistance of car windshields to the wind and earthquake resistance of building curtain walls, the performance of glass adhesives directly affects the firmness of safety defenses. Genesis takes "safety without compromise" as its research and development core, integrating safety genes into every gel tube. Whether it is precision coating on high-rise buildings or edge sealing and waterproofing in home decoration, only by integrating safety awareness throughout the entire chain of research and development, production, and use can glass glue, as an "invisible guardian", build a great wall that protects life with the toughness of millimeters.
