ThreeBond 7782
Instant Adhesive Gold Label Series
(Ultra Rapid Curing Type)
June 2006
Product Description:
hs
il.c
o.u
k
ThreeBond 7782 is an ultra-rapid curing type instant adhesive whose main component is ethyl-αcyanoacrylate. When a thin layer of the TB 7782 is applied to one of the substrates and the substrates
are laminated, the adhesive causes a chemical reaction in several seconds to a few minutes with the aid
of a trace amount of water on the bonded surfaces and becomes a rigid cured substance. It can bond
various materials remarkably quickly.
Product Benefits
• The adhesive exhibits high adhesion instantaneously (within 2 seconds to 3 minutes)
• It is a one-part adhesive, which can be used readily.
• It is a renewed product that excels in quick-curing properties and bonds various materials (porous
and acid materials) in a short time.
• It is useful in reducing the working hours and improving the working efficiency.
• It firmly bonds a wide range of materials.
Main Applications:
•
•
•
General parts that must be bonded quickly.
Bonding requiring permeability.
Temporary fixing for bonding with adhesives, such as epoxy resins and acrylic adhesives, that
require time or fixing jig to cure.

Adhesion to Various Substrates
For the test of tensile shear bond strength, the metallic test pieces were sandblasted. The test pieces of
other materials were used without treatment. The test pieces were bonded with the adhesive in an
environment with a relative humidity of 50% at 25°C , and the adhesive was cured for 24 hours in the
same environment. The adhesion was measured at room temperature.

Test Method: Tensile shear bond strength (3TS-301-11)
Adhesion Under Various Humidity Conditions
Test pieces were bonded with the adhesive under various
humidity conditions at a constant temperature (25°C ), and
the adhesive was cured in the same environment for the
predetermined time. Then, the tensile shear bond strength
was measured at room temperature.

Steel sheet test pieces were bonded with the adhesive in
an environment with 50%RH at 25°C, and the adhesive
was cured for 24 hours in the same environment. After
aging at various temperatures for predetermined time, the
test pieces were cooled to room temperature and the
tensile shear bond strength was measured (3TS-301-11).
Aluminium test pieces were bonded with the adhesive in
an environment with 50%RH at 25°C, and the adhesive

room temperature, and the tensile shear bond strength
was measured (3TS-301-11).
