PU1730 High Performance Multipurpose Auto Car glass Polyurethane PU Sealant
PU1730 High Performance Multipurpose Auto Car glass Polyurethane Urethane PU Sealant
● Multipurpose auto glass polyurethane sealants are high-strength, moisture-curing adhesives designed to bond and seal windshields, backlights, and sidelights. They provide a flexible, OEM-quality, and watertight barrier that absorbs road vibrations and withstands extreme temperatures without cracking or shrinking.
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
High Structural Bond: Delivers high tensile strength to withstand driving vibrations, chassis twisting, and aerodynamic pressure.
Non-Sag Formula: Features a heavy, high-viscosity paste consistency that stays in place without slumping when applied to vertical or overhead tracks.
Weatherproof Barrier: Cures into a tough, flexible rubber that seals out water, wind, and road noise while resisting UV radiation and extreme temperatures.
OEM-Level Safety: Keeps the windshield securely attached so passenger-side airbags can deploy properly against it during an impact
Key Features and Capabilities
Superior Bonding: Effectively adheres glass to metal, fiberglass, and painted surfaces.
Application Ease: Packaged in standard 10.5 oz or 310 ml cartridges 400ml/600ml sausage, they load easily into manual or pneumatic caulking guns. The non-sag properties make them ideal for vertical and overhead applications

●No oil permeated
●Paintable, abrasion able
●Convenient to apply
●Good aging resistance and weather resistance
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
