1. CharacteristicPolyurethane 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 aftermarket windshield replacement scenarios. It exhibits
exceptional adhesion to various automotive substrates such as
glass, painted metal, and plastic, forming a durable and elastic
bonding interface that effectively resists the stresses caused by
vehicle vibration, temperature fluctuations, and road bumps during
driving. Compared with traditional sealants, it boasts excellent
weather resistance, capable of withstanding extreme environmental
conditions including high temperatures (up to 150℃ in short-term),
low temperatures (down to -40℃), heavy rain, ultraviolet radiation,
and chemical erosion from fuels and detergents. Additionally, it
features rapid curing properties that meet the efficient production
needs of automotive factories, while its good fluidity ensures easy
application and full filling of gaps, preventing water leakage, air
infiltration, and noise transmission, thereby enhancing the overall
safety, comfort, and durability of the vehicle. 2. Features- Superior Elasticity: Maintains excellent elasticity even after long-term use, with an
elongation at break of over 300%, which can effectively absorb and
buffer the dynamic stress between the windshield and the car body,
avoiding glass cracking or seal failure.
- Strong Adhesion: Achieves firm bonding without the need for additional primers on
most automotive substrates, with a shear strength of more than
2.5MPa, ensuring the windshield remains securely attached to the
body even in emergency situations such as collisions.
- Excellent Environmental Resistance: Passes strict weathering tests, with no obvious degradation,
cracking, or discoloration after long-term exposure to sunlight,
rain, and ozone, maintaining stable performance for more than 10
years under normal use conditions.
- Efficient Curing: Under normal temperature conditions, it can form an initial
strength within 2-4 hours and fully cure within 24 hours,
significantly shortening the production cycle of new cars and the
maintenance time of after-sales windshield replacement.
- Environmental Friendliness: Complies with international environmental standards such as EU
REACH and RoHS, free of harmful substances such as formaldehyde and
heavy metals, and does not cause pollution to the environment
during production and use.
3. Application- New Energy Vehicle Assembly: Used for bonding and sealing windshields of pure electric
vehicles, hybrid vehicles, etc., while also providing auxiliary
insulation and noise reduction effects to adapt to the high-demand
driving environment of new energy vehicles.
- Traditional Fuel Vehicle Production: A core sealant product in the assembly process of passenger cars,
commercial vehicles, and trucks, ensuring the sealing performance
of windshields and improving the vehicle's airtightness and sound
insulation.
- Automotive Aftermarket Maintenance: It is widely used in the replacement and repair of damaged
windshields in 4S stores, auto repair shops, etc. Its easy-to-use
characteristics and reliable performance make it the first choice
for aftermarket sealant.
- Special Vehicle Modification: Applied to the windshield installation of modified vehicles,
off-road vehicles, and special operation vehicles (such as
emergency rescue vehicles, engineering vehicles), adapting to the
harsh working environment of special vehicles and ensuring driving
safety.
- Auxiliary Sealing of Vehicle Windows: In addition to windshields, it can also be used for the auxiliary
sealing of side windows and rear windows of some vehicles,
enhancing the overall sealing effect of the vehicle and preventing
water leakage and wind noise.
