Application

Techniques

Bond strength is dependent upon the amount of adhesive-to-surface contact developed.

Firm application pressure and moderate heat, from 100°F (38°C) to 130°F (54°C), will

assist the adhesive in developing intimate contact with the bonding surface.

To obtain optimum adhesion, the bonding surfaces must be clean, dry and well

unified. Some typical surface cleaning solvents are isopropyl alcohol or heptane.*

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.

*Carefully read and follow the manufacturer’s precautions and directions for use

when working with solvents. These cleaning recommendations may not be

compliant with the rules of certain Air Quality Management Districts in California;

consult applicable rules before use.

Environmental

Performance

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.

Application Ideas

• Foam to powder coated painted surfaces.

• Low surface energy plastic adhesion.

Application Equipment

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).
