Information
Bond strength is dependent upon the amount of adhesive-to-surface contact developed.
Firm application pressure develops better adhesive contact and thus improves bond
strength.
To obtain optimum adhesion, the bonding surfaces must be clean, dry and well unified.
Typical surface cleaning solvents are isopropyl alcohol/water mixture (rubbing alcohol) or
heptane. Use proper safety precautions for handling solvents.
It may be necessary to seal or prime some substrates prior to bonding.
a. Most porous or fibred materials (e.g. wood) will require sealing to provide a unified
surface.
b. Some materials (e.g. copper, brass, plasticised vinyl) will require priming or
coating to
prevent interaction between adhesive and substrates.
VHB Joining Systems are suited for use in many interior and exterior industrial
applications. In many situations, they can replace rivets, spot welds, liquid adhesives and
other permanent fasteners.
Each product in the VHB family has specific strengths. These can include high tensile,
shear and peel adhesion and resistance to solvents, moisture and plasticiser migration.
All VHB tapes should be thoroughly evaluated by the user under actual use conditions
with intended substrates, especially if expected use involves extreme environmental
conditions.
VHB Joining Systems are suita ble for bonding a variety of substrates, including sealed
wood, many plastics, composites and metals. Plastics which can be a problem are
polyethylene, polypropylene, PTFE, silicones and other low surface energy materials.
Plasticised vinyl bonding is dependent on the types and concentrations of plasticisers
which can migrate into the adhesives causing a reduction in bond strength; 4941 and
4945 are most resistant to plasticiser migration.
To prevent corrosion on copper and brass, only lacquer coated material should be used
within VHB Joining Systems.
Thorough evaluations are recommended when bonding is required to any questionable
surface.
