Benefits
Strong Structural Bonding
Replaces mechanical fasteners and liquid adhesives while providing a clean, smooth appearance.
Excellent Conformability
The acrylic foam adapts to uneven surfaces and helps compensate for thermal expansion between dissimilar materials.
Bonds Multiple Substrates
Provides excellent adhesion to aluminum, stainless steel, galvanized steel, glass, acrylic, polycarbonate, ABS, and painted metals.
Outstanding Outdoor Durability
Maintains bond strength under UV exposure, moisture, humidity, and temperature cycling.
Waterproof Sealing
The closed-cell acrylic foam helps seal against water, dust, and environmental contaminants.
Designed for Plasticized PVC
Its adhesive formulation resists plasticizer migration, making it suitable for bonding flexible vinyl and plasticized PVC materials.

Frequently Asked Questions (FAQ)
What is 3M™ VHB™ 4926 used for?
It is widely used for panel-to-frame bonding, stiffener attachment, decorative trim, electronic displays, signage, appliance manufacturing, and transportation applications.
How thick is 3M™ VHB™ 4926?
The nominal thickness is 0.40 mm (15 mil).
What materials can 4926 bond?
It bonds aluminum, stainless steel, galvanized steel, glass, ABS, acrylic, polycarbonate, painted metals, sealed wood, and plasticized PVC.
Can 4926 replace rivets and screws?
Yes. It is designed to replace many mechanical fasteners while providing a cleaner appearance and reducing assembly time.
Is it suitable for outdoor use?
Yes. It provides excellent resistance to UV radiation, weathering, moisture, and temperature cycling.
What makes 4926 different from 4936?
Both belong to the 4941 Family and use the same multi-purpose acrylic adhesive.
- 4926: 0.40 mm (15 mil)
- 4936: 0.60 mm (25 mil)
4926 is preferred for thinner bond lines, while 4936 offers greater gap-filling capability.
Can 4926 be die-cut?
Yes. The densified kraft paper liner provides excellent dimensional stability for precision die-cutting, kiss-cutting, and automated converting. Guangdong Yousan also offers custom converting services.
