`
`Adhesive is resistant to oxidation and ozone when exposed to air or ultraviolet light.
`

`Performance
`
`Application
`Equipment
`
`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. Some typical surface cleaning solvents are isopropyl
`alcohol or heptane.*
`*Note: Carefully read and follow the 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.
`
`Humidity Resistance: High humidity has minimal effect on adhesive performance.
`No significant reduction in bond strength is observed after exposure for 7 days at 90°F
`(32°C) and 90% relative humidity.
`UV Resistance: When properly applied, nameplates and decorative trim parts are not
`adversely affected by exposure.
`Water Resistance: Immersion in water has no appreciable effect on the bond strength.
`After 100 hours at room temperature, the high bond strength is maintained.
`Temperature Cycling Resistance: High bond strength is maintained after cycling four
`times through:
`4 hours at 158°F (70°C)
`4 hours at -20°F (-29°C)
`4 hours at 73°F (22°C)
`Chemical Resistance: When properly applied, nameplate and decorative trim parts
`will hold securely after exposure to numerous chemicals including oil, mild acids, and
`alkalis.
`
`To apply adhesives in a wide web format, lamination equipment is required to ensure
`acceptable quality. To learn more about working with pressure-sensitive adhesives
`please refer to technical bulletin, Lamination Techniques for Converters of Laminating
`Adhesives (70-0704-1430-8).
