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.
