7. FAQ
What are the unique properties of polyurethane automotive windshield sealant?
Polyurethane sealant has excellent adhesion and can firmly bond the windshield and body frame of the car. It also has good elasticity, can adapt to the vibration and deformation of the car during the driving process, while glass and metal, plastic and other different materials have a good affinity, to ensure that the sealing effect is durable, and has a certain weather resistance, can resist the influence of external factors such as sunlight, rain, temperature changes.
What are the advantages compared to other types of sealants (such as silicone sealants)?
Compared with silicone sealant, polyurethane sealant has a stronger bond to automotive windshield and body materials, especially for some surface treated automotive special materials. Its elasticity and wear resistance are also more suitable for the dynamic use environment of the car, and it performs better in terms of tear resistance and impact resistance. In addition, the hardness of polyurethane sealant after curing is relatively more suitable for the sealing requirements of automotive windshield, which can avoid excessive rigidity caused by glass damage while ensuring the sealing.
What is the temperature range of this sealant?
General polyurethane automotive windshield sealing repair adhesive has a wide temperature range and can maintain stable performance between -40 ° C and 120 ° C. It will not become brittle and fracture at low temperatures, and will not soften and deform at high temperatures, thus ensuring the sealing effect of car windshields under various climatic conditions.
Is it water resistant?
Yes, polyurethane sealant has excellent water resistance. It can form a continuous, dense sealing layer, prevent rain, car wash water and other moisture into the windshield and the body of the gap, prevent moisture caused by corrosion or damage to the internal structure of the car, and can maintain the sealing performance in a wet environment for a long time.
What is the significance of the color choice of this sealant?
Common colors are black. The color selection is mainly to match the overall appearance of the windshield and body of the car, black is a more common color, which will not be obtrusive in most cars, and can play a beautiful role to a certain extent, and also facilitate the construction personnel to identify the location of the sealant.
What is the density of sealant and how does it affect the weight?
The density of polyurethane automotive windshield sealant is generally between 1.1-1.3g /cm³. Due to its relatively small amount, in automotive windshield sealing applications, the impact on the overall weight of the vehicle is very small, almost negligible, and will not have a noticeable impact on the fuel economy or handling of the vehicle.
What role does it play in windscreen installation in the automotive manufacturing process?
In automobile manufacturing, polyurethane automotive windshield sealant is the key material for windshield installation. It can not only play a sealing role to prevent rain, dust and noise from entering the car, but also firmly bond the windshield to the body frame, which is an important part of ensuring the overall structural integrity and safety of the car. At the same time, it can also cushion the external force of the windshield to a certain extent, such as stone impact.
Can it be used to reseal old windshields?
Agreed. For older windshields, if the original sealant is found to be aging, cracking, or poorly sealed, you can use polyurethane automotive windscreen sealing repair adhesive to reseal. However, before construction, it is necessary to thoroughly remove the old sealant to ensure that the new sealant is well bonded to the windshield and the body.
