Benefits
Designed for Advanced Automotive Paint Systems
EX4008 is specifically developed for traditional and advanced automotive paint finishes, including scratch- and mar-resistant coatings.
Two Different Adhesives
Different adhesive formulations on each side maximize adhesion to both painted vehicle bodies and automotive trim materials.
Excellent Impact Resistance
Maintains reliable bonding performance under vibration and cold-weather impact conditions.
Superior Stress Relaxation
The viscoelastic acrylic foam distributes stress and compensates for thermal expansion between dissimilar materials.
Improved Vehicle Appearance
Eliminates mechanical fasteners while providing a clean, flush bond line.
Manufacturing Efficiency
Pressure-sensitive adhesive enables fast, clean installation without curing time.

Frequently Asked Questions (FAQ)
What is 3M™ EX4008 used for?
It is primarily used for permanent attachment of automotive exterior trim, moldings, wheel arch extensions, emblems, spoilers, and other decorative components.
How thick is EX4008?
The tape has a nominal thickness of 0.76 mm (0.030 in).
What makes EX4008 different from standard acrylic foam tapes?
EX4008 features two different acrylic adhesives, one on each side of the foam core, specifically designed to optimize bonding to automotive paint systems and trim materials.
Is EX4008 suitable for outdoor use?
Yes. It provides excellent resistance to UV exposure, moisture, weathering, and temperature cycling.
Can it withstand cold climates?
Yes. It is engineered to provide excellent impact resistance even under cold-weather conditions.
Can it replace clips or screws?
Yes. In many automotive trim applications, it replaces mechanical fasteners while improving appearance and reducing assembly time.
Can it be die-cut?
Yes. Guangdong Yousan provides precision die-cutting, laminating, slitting, rewinding, and custom adhesive converting services.
Is primer required?
Many automotive paint systems can be bonded directly. However, adhesion testing is recommended for specific paint formulations and low surface energy plastics.
