Typical Environmental Performance

Chemical and Environmental Exposure

The 3M™ High Temperature Acrylic Adhesive 100 is well known in industry for environmental and chemical resistance. For many applications, any one of the products

in this grouping will perform satisfactorily when exposed to di erent chemicals or temperatures. Jet fuels, however, are a challenge for pressure sensitive products.

More speci cally, the Aviation Turbine Fuel, Grade JP-4 (MIL H-T-5624), will attack many of the best adhesives within 72 hours. In response to the demands of this

market and the corresponding military speci cation MIL-T- 9906C, 3M™ Adhesive Transfer Tape 965 was developed as it di ers slightly in chemistry from the rest of

the 3M adhesive 100 family to provide the extra chemical resistance.

In addition to the added fuel resistance, 3M tape 965 retains all of the notable features of the adhesive 100: excellent adhesion to metals, good adhesion to high

surface energy plastics, low outgassing, and excellent static shear values for room temperature and heated conditions. The chart below shows adhesion values (to

stainless steel) of 3M™ Adhesive Transfer Tapes 965 and 966, with an emphasis on fuel and oil exposure.
