HARDMAN® Water-Clear Epoxy
DOUBLE/BUBBLE® Green Package #04004
PRODUCT DESCRIPTION
HARDMAN Water-Clear Epoxy is a two–component, room
temperature cure epoxy system. It offers a unique feature of
being a water–clear and transparent adhesive. This system
contains no solvents and can also be used as a coating. With
its solventless feature, it can be applied over old coatings
without raising them. It is self–leveling and blush–free so that
it will cover and fill scratches.
HARDMAN Water-Clear Epoxy is recommended for the
following substrates:
Metal
Plastic
Other
Stainless Steel
Epoxy Glass
Aluminum Phenolic
China
TYPICAL USES
HARDMAN Water-Clear Epoxy is designed to repair printed
circuit boards (it does not electrically corrode copper), optical
fibers, lenses and other optical equipment, jewelry, art objects
and other applications where a clear bond is desired.
PACKAGING
The DOUBLE/BUBBLE package is a handy, dual-pouch, one-
shot, job-size packaging concept. It reduces the waste
typically associated with the use of larger quantities of two-
component adhesives. This unique packaging ensures that
DOUBLE/BUBBLE adhesives are always factory fresh and
accurately portioned for optimum adhesive performance.
HARDMAN Water-Clear Epoxy is also available in poly bottles,
1-gallon cans, 5-gallon pails and 55-gallon drums.
HOW TO USE
Surface must be clean and dry before application. Remove all
chemicals, dirt wax and oil.
