• It is specifically designed for good adhesion to high, medium and lower surface energy plastics and paints, metals and glass
• Applications for this tape include bonding and sealing polycarbonate lens over LCD, signage and windows to post-painted control panels
• Damps vibration and reduces noise. Distributes stress
• Resists solvents and salt water. Seals and bonds even in extreme environments
• Can compensate for thermal expansion and contraction of bonded parts
• Excellent for thin materials

• Although laboratory tests have shown no degradation after 10 years submersion in salt water, VHB Tapes are not recommended for applications involving continuous submersion
• When stored in the original cartons in cool dry conditions (ideal 20°C, 50% relative humidity) the shelf life is 24 months from date of manufacture
• The elastic properties are maintained between -40°C and 90°C

• An example of VHB Tape durability has been generated on the Bendix Automotive Proving Ground in Indiana, USA.

A full size semi-truck with a sleeper cab was constructed with all exterior panels and doors taped to an underlying frame with 4950 VHB Tape. After approximately 500,000km on the harsh durability track the VHB Tape bonds remained completely intact.

This is particularly impressive as some of the mechanically joined and welded parts failed and required repairs during the test program. Testing has revealed no apparent degradation of any VHB Tape when exposed to splash testing of most common solvents, including water, petrol, white spirits, motor oil, ammonia cleaner, acetone, methyl ethyl ketone (MEK) and isopropyl alcohol. 3M VHB Tape acts as a seal against moisture and helps to prevent galvanic corrosion between dissimilar metals.

• Prevents corrosion by separating dissimilar metals
• Resists solvents and salt water. Seals and bonds even in extreme environments
•  The performance of VHB Tapes is not significantly affected by exposure to sunlight and harsh environments
• Outdoor weathering decks in Florida (hot and moist, high UV), and Arizona (hot with high UV) and other locations around the world are used to collect data on the long term performance of these tapes. These harsh tests typically show 100% bond strength retention after 2-5 years
