Application Techniques
• Bond strength is dependent upon the amount of adhesive-to-surface contact
developed. Firm application pressure helps develop better adhesive contact and
improve bond strength.
• To obtain optimum adhesion, the bonding surfaces must be clean, dry and well
unified. Typical surface cleaning solvents are isopropyl alcohol and water (rubbing
alcohol) or heptane.
Note:
Be sure to follow manufacturer’s precautions and
directions for use when using solvents.
• Ideal tape application temperature range is 70°F to 100°F (21°C to 38°C). Initial
tape application to surfaces at temperatures below 50°F (10°C) is not recommended
because the adhesive becomes too firm to adhere readily. However, once properly
applied, low temperature holding is generally satisfactory.
Application Ideas
• These products are designed for general purpose mounting and joining, and may
offer one piece removal in some applications. Surfaces and conditions for removal
should be tested by the user to determine fitness for the user’s particular purpose.
The high degree of conformability of these tapes make them ideal for joining many
rough irregular surfaces, and the closed-cell foam can make good water and air
seals in certain applications.
