Specifications and procedures subject to change without notice
No silicone based material (adhesive, film backing, release material) is used in the
manufacture of our conductive shielding grid tape.
Users shall determine the suitability of the product for its intended use.
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) periodically. 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 in ultraviolet
sunlight, moisture, or heat. Tape over one year old should be evaluated by the
user to determine acceptability for the user’s application. Desco Industries,
Inc. recommends those tracking useful life of product to use shipping/invoice
date as Desco Industries, Inc. expressly warrants that for a period of one (1)
year from the date of purchase, our Wescorp Brand ESD Tape will be free of
defects in material (parts) and workmanship (labor). See details of Limited
Warranty online at
ANSI/ESD S20.20 requires that all nonessential insulators, such as those made of
plastics and paper, must be removed from the workstation. Substituting ESD tape
for regular tape (a very high tribocharging insulator) protects your ESD susceptible
products.
