3M acrylic foam tape 4229P, dark gray, Mounting Tape, High Temperature Resistant Foam Tape, for Car, Motorcycle, Logo, Signs, Home, Outdoor

The double-sided 3M-Tape-4229P impresses with its enormous adhesion on painted surfaces, metal, glass, and many plastic surfaces. 3M 4229P is a gray, closed-cell acrylic foam tape engineered specifically for automotive attachment applications. It combines a viscoelastic acrylic foam core with high-performance pressure-sensitive adhesives to create strong and durable bonds between a variety of substrates. It is suitable for both indoor and outdoor use and can therefore be used in almost all areas.This tape is designed to replace screws, rivets, clips, and liquid adhesives in many automotive assembly operations, providing clean and efficient bonding while maintaining design flexibility.

Features:

• dark gray
• 33 meters in length
• 0.76mm thick
  Viscoelastic Core: Absorbs vibration, fills gaps on curved surfaces, and handles thermal expansion between metal and plastic parts.
  Dual Adhesives: Features different specialized adhesives on each side for optimal bonding to automotive paint clearcoats and plastic trim.
  Weather Resistant: Waterproof and durable against environmental elements.

For the attachment of e.g.:

• metal
• glass
• tiles
• external wooden parts
• decorative strips
• side moldings
• reflectors
• Mirror
• various plastics

High Bond Strength
The advanced acrylic adhesive system provides excellent adhesion to:
• Automotive painted surfaces
• Metals
• Plastics
• Composite materials
• Powder-coated substrates
The tape delivers long-lasting performance even when exposed to demanding environmental conditions.
Excellent Conformability
The acrylic foam core adapts to irregular surfaces and helps compensate for dimensional variations between bonded parts.
Benefits include:
• Improved surface contact
• Enhanced bonding performance
• Better stress distribution
• Reduced assembly tolerances
Vibration and Impact Resistance
Automotive components are continuously exposed to vibration, shock, and dynamic loads.
The viscoelastic foam core absorbs stress and dissipates energy, helping maintain bond integrity over the vehicle’s lifetime.
Weather and Environmental Durability
3M 4229P offers outstanding resistance to:
• UV exposure
• Humidity
• Rain
• Temperature cycling
• Automotive fluids
This makes it suitable for both interior and exterior automotive applications.
Simplified Assembly Process
Compared with mechanical fasteners, acrylic foam tape helps manufacturers:
• Reduce assembly time
• Eliminate drilling operations
• Improve appearance
• Reduce weight
• Lower manufacturing costs
Automotive Applications of 3M 4229P
Exterior Trim Attachment
3M 4229P is commonly used for bonding:
• Side moldings
• Body side trim
• Decorative trim strips
• Rocker panel moldings
Emblems and Nameplates
The tape provides strong and reliable attachment for:
• Automotive logos
• Brand badges
• Identification plates
• Decorative emblems
Plastic Component Bonding
Suitable for lightweight plastic components including:
• ABS parts
• PC components
• Polycarbonate trim
• Composite decorative parts
Interior Automotive Assembly
Applications include:
• Dashboard trim
• Interior decorative panels
• Control panel components
• Display bezels

3M Acrylic Foam Tape 4229P is an automotive attachment tape that brings robust performance and shear strength to attaching trim and components to clearcoat systems on automotive applications. With its dark gray, closed-cell .76 mm acrylic foam core, this tape provides stress relaxation under high load, helping ensure long-lasting durability, and maintains bond line aesthetic under normal load.

Featuring two different adhesives, one on each side, 3M™ Acrylic Foam Tape 4229P is made for effective bonding on automotive surfaces. The liner-side adhesive offers high initial and final adhesion to rigid clearcoat systems and paint. The non-liner-side adhesive works well with adhesion promoter on plastics and other common automotive trim materials. The viscoelastic foam core conforms well even to complex geometries. This automotive trim adhesive exhibits excellent plasticizer resistance. Use with 3M™ Automotive Adhesion Promoter for tape-to-part adhesion on all parts, especially plastics such as RIM, TPO, PPO, PP and PC.
