Laminating Adhesive 9472LE

Properties and

Performance

(Not for specification purposes)

Bond Build Up

The bond strength of #300LSE “Hi-Strength” Acrylic

Adhesive increases as a function of time and temperature,

and has very high initial adhesion.

Humidity Resistance

High humidity has minimal effect on adhesive performance.

No significant reduction in bond strength is observed after

exposure for 7 days at 32°C and 90% relative humidity.

U.V. 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 70ºC

4 hours at -29ºC

16 hours at 22ºC

Chemical Resistance

When properly applied, nameplate and decorative trim

parts will hold securely after exposure to numerous

chemicals including oil, mild acids and alkalis.

Temperature Resistance

The #300LSE “Hi-Strength” adhesive is usable for short

periods (minutes, hours) at room temperatures up to

148ºC, and for intermittent longer periods of time (days,

weeks) up to 93ºC.

Low Service Temperature

- 40ºC

Processing

Slitting & Die-Cutting:

This adhesive is very aggressive and may be difficult to die cut. Chilling the adhesive to

between 2

°C and 10º C will improve the processability. In addition, dies can be

lubricated with Laminoleum evaporative stamping oil

Roll Laminating:

A combination of metal and rubber rollers with moderate pressure is recommended.

Note: Please refer to the 3M Slitting/Die-Cutting Technical Bulletin for further details.
