1.
Will Chem-Tape� give a liquid tight
seal?
No, Chem-Tape� will reduce gross liquid
flow, but it is not a substitute for glove rings, attached
boots, sock booties or sealed seams. The performance
of Chem-Tape� is dictated by the care taken when applying
the product. Users should avoid wrinkles and folds when
applying the tape. Chem-Tape� utilizes a pressure-sensitive
adhesive, the optimum seal will be obtained with a high
degree of pressure during application.
2. Will using Chem-Tape� make suit gas-tight?
No, Chem-Tape� should not be used in attempt to make a gas-protective
suit from as non-gas-protective suits.
3. How should Chem-Tape� be properly applied? On what areas
of the suit should it be used?
Chem-Tape� was designed to create and improve
the liquid resistance of interfaces and closures found on protective
garments and ensembles. Chem-Tape� can be used to minimize liquid
penetration through the following interfaces; glove/sleeve, boot/boot
flap, zipper/storm flap, around respirator face pieces, etc.
Chem-Tape� should be applied by hand with a high degree of pressure.
A sufficient length of Chem-Tape� should be wound off the roll
and either cut with a knife/scissors or tornby hand by pulling
firmly and rapidly across the tape a right angle. A single continuous
length of tape should be used whenever possible. Several wraps
or lengths of tape may be necessary to obtain the desired level
of coverage and performance based on the specific scenario.
4. Is it possible to reuse Chem-Tape�?
No, Chem-Tape� is a single-use, disposable item. If you attempt
to reuse Chem-Tape� you will get limited adhesion and could compromise your protection.
5. Does removing Chem-Tape� have an effect on the chemical
resistance of the suit material?
Chem-Tape� has a very aggressive adhesive system
to maximize the bond to the fabric. Some lightweight protective
fabrics can be damaged when Chem-Tape� is removed. Temperature,
exposure scenario, and the length of time the tape has been on
a fabric will all affect the release characteristic. It is the
user�s responsibility to inspect and determine if any item of
personal protective equipment is suitable for re-use. A damage
garment should not be re-used.
6. Will chemicals affect or attack the adhesive on Chem-Tape�?
Chem-Tape� includes a polyisoprene (i.e., natural rubber) based
adhesive system that can be affected by certain chemicals. Proper application
(i.e., avoidance of wrinkles and gaps) in the tape will help to minimize degradation
of the adhesive since a flat edge minimizes the actual amount of adhesive that
is available for chemical exposure.
7. Is Chem-Tape� available in other roll sizes? What about
in other colors?
No, Chem-Tape� is available in individually shrink-wrapped rolls (2-inches wide
by 60 yards long, 5cm wide by 54 meters long). Chem-Tape� is yellow imprinted
with a black logo.
8. What is the difference between Chem-Tape� and standard
duct tape?
Standard duct tape is designed to minimize the gross leakage of air in and around
seams and joints in heating, air-conditioning, and ventilation equipment (HVAC).
Chem-Tape� is a conformable, hand-tearable, high chemical barrier closure and
attachment tape system designed to minimize the influx of hazardous particles
and liquids into the interfaces in chemical protective clothing ensembles. Chem-Tape� utilizes
the same fundamental barrier technology found in limited-use chemical protective
fabrics such as System CPF� 1-4, Tychem� and Responder�.
9. Will Chem-Tape� removal affect the chemical resistance
of gloves?
Unlikely. Most chemically resistant gloves such
as PVC, Butyl, Viton� and Neoprene are either "cured" or "vulcanized" making
them essentially unaffected by rubber-based pressure sensitive
adhesives. Film -based gloves such as the SilverShield� may be
physically affected if Chem-Tape� is removed from the glove.
In either case, the user should fully inspect the glove for signs
of physical and/or chemical deterioration/degradation and discard
if damaged.
10. Is it possible to use Chem-Tape� over serged or bound
seams to enhance holdout?
Yes, Chem-Tape� can be used to improve the performance
of seams, closures, and other interfaces present on a protective
garment or ensemble. The ultimate performance of Chem-Tape� is
dictated by how it is applied.
