Description
Paste
A preparatory priming paste used to displace
surface moisture, passivates surface oxides and
fills small irregularities in the substrate. Consists
of saturated petroleum based compound and
passivating agents. Marine Paste is a special
primer paste that contains wide spectrum biocides
that resist the growth of microbial organisms.
Mastic
A filler which profiles areas to be wrapped by
easing contours on pipe joints, flanges, valves,
bolts, and other irregular shapes. Consists of
saturated petroleum based compounds, inert
fillers, and reinforcing fibers.
Tape (A, B,
and C):
A non-woven bonded synthetic fabric, fully
impregnated and coated with natural petroleum
based compounds and inert fillers. It is chemically
inert, does not polymerize or oxidize, and retains
water resistance and dielectric properties over an
indefinite period.
Three different tapes are
available depending on the service temperatures
(130°F, 150°F, and 165°F respectively). Marine
Tape is similar to Tape "A" in that it contains a
highly effective anti-bacterial agent to protect the
substrate from microbial corrosion activities. This
tape is designed for application underwater, near
the splash zone, or on substrates in a corrosive
marine environment.
Overwrap
A stabilized, plasticized, PVC film coated with an
anti-corrosive pressure sensitive adhesive used to
wrap over petrolatum tapes to provide colorcoding and additional protective properties. It is
flexible, resists acids, alkalies, and oils.

Mechanism
Primary
Features
A petroleum-based tape wrap system developed
for the protection of metal surfaces in severe
environments and difficult to protect applications.
Products are designed to be applied over hand
or power wire brushed surfaces for above
ground, buried, and underwater applications. The
typical system involves priming the surface with
a paste, profiling around irregular shapes with a
mastic compound, and wrapping with a
petroleum tape. An optional overwrap tape is
used for additional mechanical or electrical
resistance.
Carbowrap Tape Series products are used for
the protection of piping, valves, pumps,
connectors, flanges, bolt heads or any other
difficult to protect object. They are also used in
applications where surface preparation is
minimal or inadequate for coatings; or where the
weather or ambient conditions are such that
other methods are not practical. Petrolatum tape
wrap systems provide excellent protection
against chemical splash or fume attack.
The tape wrap system is a very simple system in
its approach to corrosion control and application
for long term service. These petrolatum-based
products will totally encapsulate an object such
as a pipe or pipe flange and seal it off from
atmospheric moisture and oxygen, thereby
preventing corrosion of the metal substrate. The
petrolatum material is inherently acid and caustic
resistance, and has outstanding moisture
resistance. The system remains flexible
indefinitely and as long as the wrap is not broken
exposing the metal substrate, it will continue to
perform for extended periods of time.

Application
Tape should be spirally wrapped incorporating a 1"
overlap. For buried applications a 55% overlap is
needed to ensure a double layer. When pipe is
vertical, wrapping should commence at the bottom
and proceed upward. All overlaps should be
smoothed by hand. A 2" overlap should be used
when starting a new roll.
