Other Considerations

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 adhesion, the bonding surfaces must be clean, dry, and smooth. Some typical

surface cleaning solvents are isopropyl alcohol or heptane. Consult manufacturer's

Material Safety Data Sheet for proper handling and storage of solvents.

Ideal tape application temperature range is 70°F (21°C) to 100°F (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.
