Factory-Produced Elastic Polyurethane Automotive Front And Rear Windshield Sealant Black Waterproof Fast-Drying

1. Characteristics

2. Features

• Superior Bonding Performance: Establishes strong and reliable adhesion with various substrates, meeting the strict load-bearing requirements of automotive windshields.
• Excellent Elastic Recovery: Possesses high elongation at break and good elastic recovery rate, adapting to the thermal expansion and contraction of windshield and body materials caused by temperature changes.
• Strong Environmental Resistance: Resists UV radiation, ozone, chemical corrosion, and extreme temperature fluctuations, without losing sealing and bonding properties.
• Fast Curing and Easy Construction: Features a reasonable curing speed, allowing for efficient assembly operations; it can be applied by manual extrusion or mechanical dispensing, with good fluidity and moldability to fill irregular gaps.
• Environmental Friendliness and Safety: Complies with international automotive environmental standards, containing no harmful volatile organic compounds (VOCs) and heavy metals, ensuring safety for operators and the environment.

3. Applications

• New Car Windshield Assembly: Used as the core bonding and sealing material in the production process of passenger cars, commercial vehicles, and new energy vehicles, realizing the integrated connection between windshield and body frame.
• Windshield Maintenance and Replacement: Applied in the after-sales market for windshield repair and replacement, such as re-sealing after windshield damage or replacing aging sealant to restore the sealing and safety performance.
• Secondary Sealing of Windshield Accessories: Used for the sealing of windshield wiper bases, rearview mirror installation positions, and glass heating wire joints to prevent water seepage and ensure the normal operation of accessories.
• Special Vehicle Windshield Sealing: Suitable for the sealing needs of special vehicles such as off-road vehicles, construction vehicles, and agricultural vehicles, which have higher requirements for sealant's impact resistance and harsh environment adaptability.
