Special Type Auto Glass Polyurethane Adhesive
PU8610
∎Product Description
PU8610 is one component polyurethane adhesive with high tensile strength and elasticity.
∎Key Features
1.Bond very well with surface of variety material such as all kinds of metal, lumber, glass, polyurethane, epoxy, resin, and coating material, etc. Good cohesive force and durable elastic sealing performance
2.One component adhesive with fabulous thixotropy, it’s convenient to apply with rapid curing speed
3.Excellent water, weather and aging resistance
4.Excellent wear-resisting property, high tear strength
5.Paintable and polishable
6.No sag or flow phenomena within 30mm perpends
7.Primer required
∎Typical Applications
1.Specially used for windshield and side glass of bus, car, railway vehicle (metro, high-speed rail), ship, spaceflight, engineering machinery vehicle, carriage and special vehicle
2.For glass steel and plastic accessories (car roof, side body and car front)
3.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
