Polysulfide Sealant For Auto Windscreen Glass Polyurethane PU Sealant
Polysulfide sealants and polyurethane (PU) sealants are two different types of sealants commonly used for auto windscreen glass installation. Here are some features specific to polysulfide sealants for auto windscreen glass:
1. Excellent Chemical Resistance: Polysulfide sealants have strong resistance to a wide range of chemicals, including fuels, oils, and solvents. This makes them suitable for automotive applications where exposure to such substances is common.
2. Elasticity and Flexibility: Polysulfide sealants possess high elasticity and flexibility, allowing them to accommodate movement and vibrations without losing their adhesive properties. This helps to prevent cracks and leaks over time due to vehicle and environmental stresses.
3. Wide Temperature Range: Polysulfide sealants can withstand extreme temperature variations without losing their physical properties. They remain effective and reliable in both high and low temperature environments, ensuring long-term performance.
4. Resistance to UV Radiation: Polysulfide sealants have good resistance to UV radiation, protecting them from degradation and color change when exposed to sunlight. This feature contributes to their durability and longevity.
5. Good Adhesion to Various Substrates: Polysulfide sealants exhibit strong adhesion to a variety of substrates, including glass, metal, and painted surfaces. This versatility allows for secure bonding between the windscreen glass and the vehicle frame.
6. Thixotropic Nature: Polysulfide sealants typically have a thixotropic nature, meaning they have a higher viscosity at rest but become less viscous under shear or pressure. This characteristic makes them easy to apply and shape during the installation process.
7. Resilience to Aging and Weathering: Polysulfide sealants have good resistance to aging and weathering effects, such as exposure to moisture, ozone, and environmental pollutants. This contributes to their long-lasting performance and reliability.
Basic Uses
1. Excellent adhesion to automotive body;
2. Sealing and bonding auto glass, windshield.
