Features

• Flame resistant – meets requirements of F.A.R. 25.853(a).

• 3M™ High Temperature Aluminum Foil Tape 433L can easily be die-cut into

special sizes or shapes.

• Best results obtained when applied to a clean surface above 32°F (0°C), but tape

can be applied from 0°F to 200°F (-18°C to 93°C).

• Performance range from -65°F to over 600°F (-54°C to over 316°C). Adhesive will

gradually thermoset at high temperatures. As it thermosets, the adhesive mass

becomes firm and gradually loses its pressure sensitivity but will continue to hold the

tape in place.
