1. Characteristics

Polyurethane automotive windshield sealant is a high-performance adhesive product specifically designed for the bonding and sealing of automotive windshields, suitable for both new car assembly lines and windshield replacement scenarios in after-sales maintenance. It operates stably across a wide range of extreme environmental conditions, from the low temperatures of -40℃ in frigid regions to the high temperatures of 120℃ in hot summers, and can resist the erosion of rainwater, automobile exhaust, road salt, and ultraviolet radiation for a long time without losing its sealing and bonding properties. A key advantage of this sealant lies in its excellent elastic recovery and high shear strength: it can effectively absorb and buffer the vibration and impact generated during vehicle operation, preventing the windshield from loosening or cracking due to mechanical stress, while forming a permanent and reliable bond with both the glass and the automotive body (including metal and plastic substrates) to ensure the structural integrity of the windshield. Additionally, it exhibits good chemical compatibility, does not corrode the surface of the windshield or the automotive paint, and complies with strict automotive industry environmental and safety standards, making it an indispensable core material for ensuring driving safety and enhancing the durability of automotive components.

2. Features

Superior Bonding Strength: It has strong adhesion to various substrates such as glass, steel, aluminum alloy, and modified plastics, forming a bond that is even stronger than the glass itself in some cases, effectively avoiding windshield detachment accidents.
Excellent Elasticity and Flexibility: With a high elongation at break (usually more than 300%), it can adapt to the thermal expansion and contraction of the windshield and automotive body caused by temperature changes, maintaining a tight seal at all times.
Outstanding Weather Resistance: It has excellent resistance to UV aging, ozone, and chemical media, and can maintain stable performance for more than 10 years under outdoor exposure, avoiding problems such as hardening, cracking, and water leakage.
Rapid Curing Performance: It adopts a moisture-curing mechanism, which can cure quickly at room temperature. The surface can be tack-free within 1-2 hours, and it can reach the initial bonding strength in 24 hours, greatly improving the efficiency of automobile assembly or maintenance.
Easy Construction: It has a suitable viscosity, can be smoothly extruded through a glue gun, and has good thixotropy, which can prevent sagging during vertical construction and ensure a neat and uniform glue line.

3. Applications

New Energy Vehicle and Traditional Fuel Vehicle Assembly: It is widely used in the bonding and sealing of windshields during the production of passenger cars, commercial vehicles, SUVs, and pickup trucks, providing structural support and sealing protection for the entire vehicle.
Automotive Windshield After-sales Replacement: It is the core material for professional maintenance institutions to replace damaged windshields, ensuring that the replaced windshield has the same bonding strength and sealing performance as the original factory.
Sealing of Automotive Glass Accessories: It can be used for the bonding and sealing of small glass parts such as automotive side windows, rear windows, and sunroofs, especially for scenarios requiring high sealing performance (such as waterproof and sound insulation).
Special Vehicle Modification: It is applied in the glass installation and sealing of modified vehicles (such as off-road vehicles, racing cars) and special-purpose vehicles (such as ambulances, police cars), adapting to the special use environment and performance requirements of modified vehicles.
Automotive Body Sealing Auxiliary: In addition to glass bonding, it can also be used for the sealing of gaps between automotive body panels and glass, enhancing the overall waterproof, dustproof, and sound insulation effects of the vehicle.
