Windshield Sealant 2 hours – 1st KLASS (310ml)

This 2-hour windshield sealant provides high-modulus structural bonding for modern vehicles, including those equipped with airbags.
It is formulated for quick curing while maintaining excellent mechanical properties, torsional rigidity, and vibration resistance.

The product is non-conductive and prevents galvanic corrosion on aluminum body panels. Its strong adhesive capability allows it to bond glass, painted surfaces, GRP panels, metal sheets and reinforced plastics.
