Normal use of our High Temperature Masking Tape is for
masking or protective applications on printed circuit boards
not exceeding temperatures of 150°C (302°F) at a duration
under 45 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,
non-staining
• Protective purposes in manufac uring processes, strips
t
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)
• For best results, apply to band using a rubber roller.
• Thick conductive adhesive excellent for conformability to
protect critical PCB features
• Easily handles high temperatures of wave soldering
without leaving significant residue
• Handles temperatures found in test and burn-in ovens

SECTION II - PHYSICAL/CHEMICAL CHARACTERISTICS
Polyimide Film
Electrically conductive particles embedded in a layer of polysiloxane adhesive
SECTION III - HAZARDOUS INGREDIENTS
No hazardous materials present
(1) According to Commission Directive 88/379/EEC (Article 3 6aa).
SECTION IV - FIRST AID MEASURES
4.1. Skin: No irritation is expected from handling the tape, however ensure good industrial hygiene and wash exposed areas with soap
and Water.
4.2. Eyes: Rinse opened eye for several minutes under running water.
4.3. Inhalation: Not a probable route of exposure for adhesive tape. Exposure to the encapsulated electrically conductive articles in the
adhesive layer is not likely.
4.4. Ingestion: Not a probable route of exposure for adhesive for adhesive tape. Treat symptomatically.
4.5. Other first aid information: Not known
SECTION V - FIRE EXTINGUISHING MEASURES
5.1. Extinguishing media: Carbon dioxide, foam, dry powder, or fine water spray.
5.2. Unsuitable extinguishing media: None known
5.3. Unusual firefighting hazards: None known
5.4. Special firefighting procedures: Self-contained respirator should be worn.
5.5. Other recommendations: None known
5.6. Combustion products: Polyimide film chars but does not burn in air, however it will burn in an atmosphere of 100% oxygen. The major
off-gases are carbon dioxide and carbon monoxide. The silicone adhesive layer also tends to char leaving residues of silica and off-gases
containing carbon dioxide, traces of incompletely burned carbon products and formaldehyde.
SECTION VI - ACCIDENTAL RELEASE MEASURE
6.1. Personal protection: Avoid contact with eyes.
6.2. Precautions to protect the environment: None established
6.3. Clean up procedure: Pick up to prevent floor
SECTION VII - HANDLING AND STORAGE
7.1. Handling precautions: Avoid contact with eyes. Ensure good industrial hygiene and wash skin with soap and water after contact.
7.2. Storage: No special measures are required.
7.3. Unsuitable packaging materials : None known.
7.4. Incompatibilities: None known.
7.5. Other information: None known.
SECTION VIII - EXPOSURE CONTROLS AND PERSONAL PROTECTION
8.1 Exposure controls: Safe handling/usage of Wescorp ESD Hi Temp Polymide Tape at high temperatures (above 200°C/392°F) requires
adequate ventilation. Using small quantities normal air circulation may be adequate otherwise further ventilation measures are recommended.
8.2. Exposure controls for hazardous components: No hazardous materials present
8.3. Personal protective equipment:
Respiratory: Not required for normal handling.
Protective gloves: Not required for normal handling, if tape is hot gloves are recommended as good industrial practice.
Eye/Face: Safety glasses are recommended as good industrial practice.
Industrial Hygiene: Wash after handling, especially before eating, drinking or smoking. Exercise good industrial hygiene practice.
