Benefits
Automotive OEM Performance
Specifically engineered for permanent attachment of automotive exterior and interior trim while meeting demanding OEM requirements.
Excellent Gap Filling
The 1.6 mm acrylic foam core compensates for larger surface irregularities and manufacturing tolerances, creating a clean and durable bond line.
Superior Stress Relaxation
The viscoelastic foam absorbs vibration, thermal expansion, and mechanical stress, helping maintain long-term bond reliability.
Strong Adhesion
Provides high initial tack and exceptional final adhesion to automotive paints, metals, glass, and engineering plastics.
Outstanding Environmental Resistance
Offers excellent resistance to UV exposure, moisture, weathering, solvents, and temperature cycling for long-term outdoor performance.
Improved Assembly Efficiency
Replaces mechanical fasteners such as screws, rivets, and clips while reducing weight and improving product appearance.

FAQ
What is 3M™ GT7116 used for?
GT7116 is designed for permanently bonding automotive exterior and interior trim such as claddings, rocker panels, spoilers, wheel arch extensions, sensor brackets, and decorative moldings.
How thick is GT7116?
The nominal thickness is 1.6 mm (0.064 inch).
Is GT7116 suitable for outdoor applications?
Yes. It provides excellent resistance to UV exposure, weathering, moisture, solvents, and temperature cycling, making it ideal for long-term automotive exterior applications.
Can GT7116 replace mechanical fasteners?
Yes. GT7116 is widely used to replace screws, rivets, and clips while improving appearance and reducing assembly complexity.
Can GT7116 be die-cut?
Yes. Guangdong Yousan offers precision die-cutting, slitting, laminating, rewinding, and custom converting services.
What is the difference between GT7112, GT7116, and GT7120?
- GT7112: 1.2 mm
- GT7116: 1.6 mm
- GT7120: 2.0 mm
GT7116 provides greater gap-filling capability and vibration damping than GT7112 while remaining highly conformable for complex automotive trim applications.
