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
temperature of about 300°F for a duration of 1 hour or
until it is cured out (not holding its adhesive)
3) Storage time
- 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
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). This tape is non-staining under
normal use as described above.
Applications for High-Temp Masking Tape
• Silk screening applications
• Masking application in spray and brush painting, nonstaining
• Protective purposes in manufacturing processes, strips
clean
• For securing polyethylene sheeting to walls during
painting
• For OEM repair shops
• Use in applications masking PCBs gold features for wave
soldering or soldering under 302°F (150°C)
• Thick conductive adhesive excellent for conformability to
protect critical PCB features
• Ideal for masking gold leads and other components on
boards populated with sensitive integrated circuits
• Easily handles high temperatures of wave soldering
without leaving a residue
• Handles temperatures found in test and burn-in ovens

Tape Dispenser
2 inch wide Tape Dispenser Item #81281
• Use with Wescorp antistatic tapes
• For tapes with 3" Cores
• For tapes up to 2" wide

Proper Storage of Tape Rolls
For best results, tape inventory should be continually
replenished. It is recommended that rolls of tape be stored
flat and rotated (flipped over to the other side) 6 to 8 weeks.
Tapes should be stored in a dry, well ventilated room with a
reasonably consistent temperature of 68° F (20° C) and be
protected from exposure to direct sunlight. Tape should not
be stored while exposed to ultraviolet sunlight, moisture, or
heat. Tape over one year old should be evaluated by the
user to determine acceptability for the user's application.
Master packs are date coded.
Desco's Wescorp™ ESD Tape line, if stored under proper
conditions (see Note above) should retain its ESD technical
properties as described by each corresponding Technical
