No Sag Performance for Vertical & Overhead Glass
Eliminates the risks of bead slumping, glue run-off, and heavy windshield displacement on vertical vehicle pillars and overhead panoramic roof systems.
Vertical Bus & Truck Windscreens
Upright front windscreens in commercial trucks and transit buses impose severe downward shear gravity on uncured adhesive. PA-160N's ultra-high thixotropy holds heavy glass panels firmly without downward drift.
Panoramic Sunroofs & Overhead Glass
Horizontal and overhead roof module installation demands adhesives that never drip or string onto car interiors. PA-160N maintains crisp triangular beads during upside-down application and roof panel placement.
Slanted Side Windows & Specialty Vehicles
Agricultural machinery cabs, construction excavators, and rail locomotive curved side windows present complex bonding angles. PA-160N provides immediate green grab and high shear security across all contours.
High Viscosity + High Initial Tack = Zero Sag Installation
When installing heavy panoramic or commercial vehicle glass, low-viscosity adhesives deform under self-weight. PA-160N balances high shear-thinning extrusion ease with instantaneous recovery of high standing viscosity.
Advanced Thixotropic Polyurethane Matrix
Extrudes smoothly through professional pneumatic guns under shear, then immediately locks into place with zero slump or run-off.
Immediate Green Grab
High initial tack holds the glass in the exact mounted position, drastically reducing reliance on alignment suction cups and exterior tape.
98% High Solid Content
Near-zero solvent shrinkage ensures the bead retains full contact thickness and gap-filling geometry throughout the 24-hour cure cycle.
400% Elastic Shock Absorption
Provides permanent flexibility to absorb extreme chassis twisting, heavy vibration, and thermal expansion cycles from −40°C to +90°C.
