3M™ Adhesive Transfer Tapes with Specialty

Acrylic Adhesive

9379, 9380

Technical Data Sheet

Product Description

chemicals like jet fuel or hydraulic fluid and to have a wide operating temperature range.

The product comes in rolled tape format of varying width.

Environmental Performance

The properties defined are based on the attachment of impervious materials (such as aluminum) to an aluminum test

surface.

Bond Build-up: The bond strength of 3M™ 9379/9380 adhesive increases as a function of time and temperature.

Humidity Resistance: High humidity has a minimal effect on adhesive performance. Bond strengths are generally higher

after exposure for 7 days at 90°F (32°C) and 90% relative humidity.

U.V. Resistance: When properly applied, the adhesive bond between impervious parts is not adversely affected by

outdoor exposure.

(70°C) followed by 4 hours at -20°F (-29°C) followed by 16 hours at 72°F (23°C).

Chemical Resistance: When properly applied, the adhesive bond between impervious parts will hold securely after

periods up to 300°F (149°C). Low Temperature Service: -40°F (-40°C). Bonded substrates should be evaluated for

continuous low temperature exposure service.
