PU1731 GERNERAL PURPOSE AUTO WINDSHIELD GLASS PU ADHESIVE SEALANT GLUE
PU1731 GERNERAL PURPOSE AUTO WINDSHIELD GLASS PU ADHESIVE SEALANT GLUE
● General-purpose polyurethane (PU) auto glass adhesives are single-component, moisture-curing sealants designed to bond windshields, rear windows, and side glass to vehicle frames. They provide a highly elastic, vibration-absorbing, and watertight seal that is essential for preventing leaks and withstanding road stress.
Multipurpose Auto Glass Polyurethane Sealant is the industry standard adhesive for installing, bonding, and sealing automotive windshields, backlights, and side glass. It serves as a structural component of the vehicle, ensuring cabin integrity and passenger safety during a collision or rollover.
Key Performance Benefits
Weather & Temperature Resistance: Maintains a strong grip in extreme heat, freezing cold, and provides high resistance to UV rays.
Vibration Dampening: Flexes with the vehicle to absorb shocks and vibrations, preventing cracks and glass displacement.
Primerless Adhesion: Many modern general-purpose formulas adhere cleanly to glass, metal, fiberglass, and painted surfaces without needing a separate primer.
PU 6030 Light yellow translucent Polyurethane potting compound
PU 6030 is a two-component solvent-free polyurethane material at room temperature or heat curing. It is light yellow and transparent after curing. It is used for two-component sealing, filling, flame and other fields. The raw material does not contain heavy metals, green environmental protection, wide process operability, high physical properties of the finished product, and good adhesion to the substrate. Room temperature and heating curing can be, can be deep curing, curing less heat, low shrinkage rate; Excellent
flexibility after curing, with good flame retardant effect.
l Excellent low temperature characteristics, excellent weather resistance
l Excellent flame retardancy, 94 V-0
l Excellent electrical insulation, stability
Typical application
