The Selection of Windshield Adhesive Must Not Be Careless!

For a long time, in the understanding of private owners and auto repair industry, windshield adhesive is only a "supporting role" positioning, owners will pay attention to the brand of windshield and the proficiency of the installation technician when replacing the windshield, but rarely pay attention to the bonding strength and service life of automotive glass adhesive. Resulting in low-quality adhesives and common building sealants flooded in the windshield repair market, causing great safety hazards to the repaired vehicles.

In the automotive assembly industry, windshield bonding adhesive, as a connection material for automotive glass and body, will not only stay on the car permanently, but also play an important safety role. On the one hand, it is used to strengthen the strength of the entire body, and on the other hand, it is mainly displayed in the passive safety protection of the vehicle.

Often the maintenance master asked,they will be the construction of glass sealant car glass for many years have no owner complaints.In fact,the window glass is not leaking,but the strength of the vehicle has decreased,which may cause the body to leak;As a passive safety protection,the safety to windshield pu adhesive plays a role in extreme  circumstances, like an airbag. Few people have experienced the effects of airbags, but they protect tens of thousands of lives in fatal traffic accidents around the world each year. (In all potentially fatal crashes, the survival rate is about 60% when seat belts and airbags are used correctly and in combination.) In traffic accidents, windshields fly out and people fly out. High strength, high quality glass glue as much as possible to avoid these should not happen tragedy.

The bonding and sealing of the automobile windshield is a very important process in the automobile assembly process, and the use of adhesive is strict, requiring the sealant to have high strength, tear resistance, excellent sealant performance, and good weather resistance and durability. In the process of use, the construction process of the sealant is simple, and the moving time is short. The windshield pu sealant should provide the overall rigidity of the car after curing, increasing the retention rate when the glass breaks.

What should be noted after the replacement of car glass?

At present, the front windshield of most models is laminated glass, laminated glass is safety glass, if it encounters external forces or stone strikes, the glass will only crack, it will not break. The rear windshield and side window glass are mostly tempered glass. Once the tempered glass receives a strong external force, it will break and form a fine particle, which can reduce the injury to the person. The front and back windshield glass are fixed to the car body by professional glass glue. Usually, this windshield glass sealant according to different quality and seasonal factors, generally completely dry cycle is 1 to 3 days, so in this period of time is not completely dry, need to pay attention to the following points:

1. In order to prevent air leakage and water leakage, do not wash the car for three days, and then tear down the tape fixing the windshield position after three days.

2. To drive smoothly, avoid emergency braking and rapid acceleration.

3. Try to avoid driving too much bumpy road sections to prevent the windshield glass from shifting.

4. Control the maximum speed within 80 kilometers per hour and avoid running at high speeds.

5. After replacing the rear windshield, the window cannot be opened during the first three days to prevent the rear windshield from shifting due to joyriding.

6. Do not insert the parking card into the gap between the front windshield and the center console.
