Benefits
OEM-Qualified Performance
Developed specifically for permanent bonding of automotive exterior and interior trim components.
Superior Gap Filling
The 1.2 mm acrylic foam core effectively compensates for uneven surfaces and manufacturing tolerances.
Excellent Stress Relaxation
The viscoelastic foam absorbs vibration, impact, and thermal movement between different materials, reducing stress on bonded joints.
Strong Long-Term Adhesion
Provides excellent initial tack and develops very high final adhesion to automotive paints, metals, plastics, and glass.
Outstanding Outdoor Durability
Resists UV exposure, moisture, road salt, solvents, and temperature cycling throughout the vehicle’s service life.
Improved Manufacturing Efficiency
Eliminates the need for screws, rivets, and clips while simplifying assembly and improving product appearance.

FAQ
What is 3M™ GT7112 used for?
GT7112 is designed for permanently bonding automotive exterior trim, including claddings, rocker panels, spoilers, wheel arch extensions, pillars, and decorative moldings.
How thick is GT7112?
The nominal thickness is 1.2 mm (0.047 inch).
Is GT7112 suitable for outdoor automotive applications?
Yes. It provides excellent resistance to UV exposure, weathering, moisture, solvents, and temperature cycling, making it suitable for long-term exterior use.
Can GT7112 replace mechanical fasteners?
Yes. GT7112 is widely used to replace screws, rivets, and clips while reducing vehicle weight and improving appearance.
Can GT7112 be die-cut?
Yes. Guangdong Yousan offers precision die-cutting, slitting, laminating, rewinding, and custom converting services.
What is the difference between GT7110, GT7112, and GT7116?
- GT7110: 1.0 mm
- GT7112: 1.2 mm
- GT7116: 1.6 mm
GT7112 provides greater gap-filling capability and vibration damping than GT7110 while maintaining excellent conformability and long-term durability.
