One Component High Bonding 6 Mpa Auto Glass Polyurethane Adhesive   PU1611


PU1611 is one-component polyurethane adhesive with very good tensile strength and elasticity, primerless, can be used for Automotive and bus industry.


∎Key Features

High Viscosity




 Excellent thixotropy, non-sag properties

 Fast adhesion to substrates

 Paintable and polishable

 Excellent wear-resisting property

 Automotive OEM quality

 No oil permeated


∎Areas of Application

Specially used for the windshield and side glass of bus, car, railway vehicle (metro, high-speed rail), ship, spaceflight, engineering machinery vehicle, carriage and special vehicle

For glass steel and plastic accessories (car roof, side body and car front)

For bonding different material (such as metal, plastic, and glass) which requires high tensile strength and elasticity, the bonding can bear high mechanical deformation force


Curing DegreeGraph

PU1611 cures by reaction with atmospheric moisture. The curing speed lower at lower humidity or lower temperature.


Chemical Resistance

PU1611 is excellent resistant to fresh water, saltwater, sewage water and acids.

Temporarily resistant to fuels, mineral oils, vegetable and animal fats and oils.

Not resistant to organic acids and caustic solutions or solvents.
