Benefits
Optimized for Modern Paint Systems
The liner-side adhesive is engineered for traditional, medium surface energy (MSE), and scratch-resistant automotive paint systems, while the opposite side bonds securely to automotive trim materials.
Strong, Permanent Bond
Provides durable attachment for exterior automotive components while replacing screws, rivets, clips, and liquid adhesives.
Excellent Stress Relaxation
The viscoelastic acrylic foam absorbs stress caused by vibration, thermal expansion, and vehicle movement, improving long-term bond reliability.
Superior Environmental Durability
Designed to withstand UV exposure, humidity, rain, road salt, and automotive temperature cycling.
Improved Vehicle Appearance
Creates a smooth, invisible bond line without exposed mechanical fasteners.
Increased Manufacturing Efficiency
Pressure-sensitive adhesive allows immediate handling with no curing time.

Frequently Asked Questions (FAQ)
What is 3M™ EX4011 used for?
It is primarily used for permanently attaching automotive exterior trim, rocker panels, wheel arch extensions, claddings, spoilers, and other decorative components.
What is the thickness of EX4011?
The nominal thickness is 1.14 mm (0.045 in).
What makes EX4011 different from EX4008?
EX4011 uses the same Acrylic Plus technology but has a thicker 1.14 mm foam core, providing greater gap-filling capability and improved stress distribution for larger trim components.
Is EX4011 suitable for outdoor automotive use?
Yes. It is designed to resist UV exposure, moisture, weathering, and automotive environmental conditions.
Can it replace screws or clips?
Yes. It is widely used by automotive manufacturers to replace mechanical fasteners, improving appearance and reducing assembly complexity.
Can EX4011 be die-cut?
Yes. Guangdong Yousan provides precision die-cutting, slitting, laminating, rewinding, and custom adhesive converting services.
Does EX4011 require primer?
Many automotive paint systems can be bonded directly. However, adhesion testing is recommended for specific paint formulations and low-surface-energy plastics.
