What causes residue problems (excessive stickiness) for
masking tape?
1) Direct sunlight [ultra-violet radiation]
2) Usage shelf life is the combination of time and heat a
3) Storage time
Applications for High-Temp Masking Tape
• Silk screening applications
• Masking application in spray and brush painting, non-
• Protective purposes in manufacturing processes, strips
• For securing polyethylene sheeting to walls during
• For OEM repair shops
• Use in applications masking PCBs gold features for wave
• Thick conductive adhesive excellent for conformability to
• Ideal for masking gold leads and other components on
• Easily handles high temperatures of wave soldering
• Handles temperatures found in test and burn-in ovens
Normal use of our High Temperature Low Charging tape is
for masking or protective applications on printed circuit
boards not exceeding temperatures of 150°C (302°F) at a
duration under 60 minutes. If the tape is used for masking
operations or temporary protection, it should not be left on
the product for more than 24 hours. For best results, the
tape should not be exposed to ultraviolet rays or high
temperature for prolonged periods of time (beyond
manufacturer's specs).
normal use as described above.
temperature of about 300°F for a duration of 1 hour or
until it is cured out (not holding its adhesive)
- if stored flat (72°F) and rotated every 6-8 weeks, the
product should be evaluated every 12 months
- if stored in a hot environment (>70°F) then the tape
should be evaluated every 6 months or less
