Information

High quality POLYURETHANE SEALANT FOR WINDSHIELD GLAZING is widely used in the automotive industry. Polyurethane sealant is mainly used forwindshield inlay, caulking / weld sealing, structural sealing, interior bonding, floor bonding and sealing, air conditioning luggage compartment bonding and sealing, and other bonding and sealing.

QUALITY POLYURETHANE SEALANT FOR WINDSHIELD GLAZING is a very important variety in automobile assembly process. It is used for bonding and sealing windshield and side window glass, replacing the traditional assembly process and improving the safety factor of the whole vehicle. According to statistics, at present, polyurethane sealant is used for 100% of the windshield bonding of domestic passenger cars. More and more passenger cars, especially the windshield and side window bonding and sealing of high-end luxury passenger car manufacturers, are also promoting this technology to improve the comprehensive performance of the whole vehicle. The utilization rate of polyurethane sealant in the windshield bonding of the whole automobile industry can reach 95%.

Design requirements for QUALITY POLYURETHANE SEALANT FOR WINDSHIELD GLAZING
Due to safety considerations, ordinary glass cannot be used for automobile glass, so there are generally only two kinds of common automobile glass, tempered glass and laminated glass. According to GB 9656-2003 automobile safety glass, the windshield must have good vision and sufficient strength. In case of vehicle accident, the windshield can protect the drivers and passengers.

The bonding and sealing of windshield is a very important process in the automobile assembly process, and the glue requirements are also very strict. The sealant is required to have high strength, tear resistance and excellent sealing performance, which can improve the overall rigidity of the automobile body, and it is also required to have excellent weather resistance and durability in the process of use.

One component polyurethane sealant for automobile must meet the tensile strength ≥ 6.0MPa, and must be tested for heat resistance, moisture and heat resistance, artificial climate accelerated aging (xenon arc lamp), water resistance and other aging properties.
