Odorless Adhesive for Enclosed & Premium Spaces
Where passenger comfort, cabin air quality, and technician safety are non-negotiable. PA-145N solves the odor complaints typical of conventional solvent-containing polyurethane adhesives.

Luxury Passenger Cars & 4S Shops
Premium vehicle owners expect pristine cabin environments without harsh chemical smells after windshield replacement. PA-145N eliminates pungent vapors, allowing rapid customer delivery without odor dissatisfaction.

Rail Transit & Subway Train Windows
Rail coaches and metro cars are sealed, high-traffic spaces with strict interior air standards. PA-145N fulfills high elongation (400%) for track vibration absorption while maintaining zero irritating emissions during assembly.

Coach Buses & Specialty Enclosures
Large bus windshields and side glass bonding require high bonding elasticity and zero solvent entrapment in large cabins. PA-145N provides moderate Shore A 55 hardness, facilitating periodic maintenance and secondary glass servicing.
