Maxtech PU1611  6Mpa High Bonding PU Bus Windshield Adhesive


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

Suitable for adhesion between windshield/side glass and frame of cars, buses, and special vehicles

A range of one-component polyurethane adhesives, designed for windscreen, side and rear window bonding.

∎Key Features


● High Viscosity

● No DOP

● Primerless

● Odorless

● Excellent thixotropy, non-sag properties

● Fast adhesion to substrates

● Paintable and polishable

● Excellent wear-resisting property

● Automotive OEM quality

● No oil permeated

● High bond strength designed for windshield bonding and stationary glass attachment


∎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

●Suitable for adhesion between windshield/side glass and frame of cars, buses, and special vehicles,to bond and seal vehicle windshields, backlights and sidelights, skylight.
