High Strength Double Coated Tape
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:
Chemical Resistance: When properly applied, nameplate and decorative trim parts
will hold securely after exposure to numerous chemicals including oil, mild acids
and alkalis.
• Foam to powder coated painted surfaces.
• Low surface energy plastic adhesion.
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).
