Product Description:

3M™ VHB™ Tape 4910 is a 0.040 inch (1.0 mm) thick clear double coated acrylic foam tape with PE film liner. The general purpose acrylic adhesive on both sides bonds to a broad range of high surface energy substrates including metals, glass and easier to bond paints and plastics. The clear tape is good for bonding transparent or translucent materials or for applications where colorless is a benefit. 3M™ VHB™ Tape 4910 is part of the 4910 tape family. Each product in this family has general purpose acrylic adhesive and firm foam but varies in thickness.

Features:

• Fast and easy-to-use permanent bonding method provides high strength and long-term durability
• Virtually invisible fastening keeps surfaces smooth
• Can replace mechanical fasteners (rivets, welds, screws) or liquid adhesives for transparent applications
• Clear, 0.040 in (1.0 mm), general purpose adhesive and clear acrylic core
• Eliminate drilling, grinding, refinishing, screwing, welding and associated clean-up
• Creates a permanent seal against water, moisture and more
• Pressure sensitive adhesive bonds on contact to provide immediate handling strength
• Allows the use of thinner, lighter weight and dissimilar materials

Handling/Application Information:

Surface Preparation

Clean

Most substrates should be cleaned with a 70/30 mixture of (IPA*)/Water prior to applying 3M™ VHB™ Tape. Exceptions that may require additional surface preparation include:

• Abrasion: Abrading a surface, followed by cleaning with IPA/water, can remove heavy dirt or oxidation and can increase surface area to improve adhesion.
• Heavy Oils: A degreaser or solvent-based cleaner may be required to remove heavy oil or grease from a surface and should be followed by cleaning with IPA/water.
• Adhesion Promoters: Priming a surface can significantly improve initial and ultimate adhesion to many materials such as plastics and paints.
• • Porous surfaces: Most porous and fibered materials such as wood, particleboard, concrete, etc. need to be sealed to provide a unified surface.
• Unique Materials: Special surface preparation may be needed for glass and glass-like materials, copper and copper containing metals, and plastics or rubber that contain components that migrate (e.g. plasticizers)

Tape Usage:

Before application, the surface must be free from oil, dust and any solvent. For the best performance, apply the tapes at room temperature between 15°C and 35°C.

Use the right amount of VHB™ Tape to handle the expected stresses. Because 3M™ VHB™ Tapes are viscoelastic by nature, their strength and stiffness is a function of the rate at which they are stressed. They behave stronger when experiencing a higher rate of stress load (dynamic stresses) and will tend to show creep behavior with stress loads that act over a long period of time (static stresses). As a general rule, for static loads, approximately four square inches of tape should be used for each pound (57 cm² of tape per kg) of weight to be supported in order to prevent excessive
