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.

Application Ideas
• Moisture barrier around doors and windows to help prevent fogging of glass.
• Seal for automotive air bag inflators.
• To hold insulation on hot air ducts in industry.
• Cover resistance wire heating elements to distribute the heat.
• Splice jumbo rolls of aluminum foil or holding the last lap of narrow width rolls in
preparation to annealing the rolls.
• Ideal as a heat reflective wrap along or over insulations, applied to tubes, engine
support structures, missile ground handling equipment, or as a protector from other
heat source areas such as hot areas in steel mills.
• Good holding, splicing, patching or general protecting tape on many applications
involving high temperatures.
