007 James Bond Tester
Pull Off Adhesion Tester
The James Pull Off
Adhesion/Bond Tester measures the pull force used to pull a 2" or 3"
disc away from the material being tested. This pressure is displayed on
a precision gauge and can be related directly to the strength of the
adhesion to the surface being tested.
The
James Pull Off Adhesion/Bond Tester has been successfully used to
verify the quality of existing materials, determine the adhesion
strength of shotcrete, epoxies, paint and other repair materials or coatings.
Each System comes with 10, 2 inch ( 50mm ), ASTM
Standard and 10, 3 inch (75mm) stainless steel discs
Customers who purchase this also need the T-M-170 Moisture
Master or T-HT-1000 Humitest for substrate moisture testing
Accurate bond strength of repair mortars, epoxy resin, laminates, overlays, and other coatings.
Calibrated gauge with maximum load indicator.
Viscose damping mechanism to protect against sudden load
release.
Adjustable
alignment plate with built in leveling
facility.
Compact design.
Easy to use.
Adequate direct
tensile strength between two layers is important if repairs to concrete
structures or additional overlays on existing concrete are to be
structurally sound. The 007 James Bond Tester involves bonding a
circular steel disc to the surface by means of an epoxy resin adhesive. A
controlled tensile force is then applied to the disc and failure will
occur at the weakest point: either in the host material, or in the bond
between overlay and host material. Knowing the surface area of the disc
and the force applied at failure, the tensile strength of the host
material or bond can be calculated.
The
007 James Bond Test Kit consists of:
Hand operated
Puller.
0--3300 lbs force (15 KN) calibrated gauge with maximum load
indicator and viscose damping to protect against sudden load release.
Adjustable
alignment plate with built in leveling facility.
Pull
bolt with coupling.
10 three inch (75 mm)
diameter steel discs.
10 two inch (50 mm)
diameter steel discs.
Carrying case
Q. Bond disc will not
stick to surface
A. You may have not mixed epoxy fully
and it won't dry.
Q. Disc pops off surface
at a low strength
A. Surface may not have been
cleaned
properly. A good indication of this would be little bits of concrete
stuck to the bottom of the disc. You may also not have a level surface.
Q. When doing a test to
check bonding strength on a roadway, do you have to take the test to
failure?
A. Yes and
no. Make sure you follow the specs for each job you do,
some may want you to take it failure, while others may want you to just
take it to a certain strength.
Q. When I crank the
handle down, the gauge does not move.
A. Chances are you need to fill the
puller with oil.
Q. How much epoxy do I
put on the bond disc?
A. You need just a thin layer, about 3
for 4 sheets of paper.
