Windshield Sealant 30 minutes – 1st KLASS (310ml)

This 30-minute windshield sealant is engineered for maximum safety and efficiency.
Its ultra-rapid curing ensures a Drive Away Time (DAT) of just 30 minutes, meeting FMVSS 208/212 safety standards, making it ideal for vehicles with driver and passenger airbags.

It features low electrical conductivity, making it suitable for vehicles with integrated antennas and aluminum bodies, preventing galvanic corrosion.
The sealant provides strong elastic-structural bonding between materials exposed to thermal expansion and vibration, including painted metal, glass, GRP and reinforced plastics.

What it’s for:

• Direct glazing installations
• Replacement bonding of front, rear and side automotive glass
• Bonding composite panels (GRP roofs, panels, fairings)
• Structural elastic bonding exposed to heavy vibration or torsion

Features

• One-component polyurethane
• Solvent-free, odorless
• Very fast curing
• High Modulus (improves NVH and body rigidity)
• Non-conductive (safe for aluminum bodies and antennas)
• High-viscosity, non-sag thixotropic paste
• Withstands high dynamic stress
• Suitable for cold and hot application
