REPORT 0F TEST
November 13, 1991
SUBJECT: Client supplied on pint of paint marked AH2377
on 10/29/91.
AUTHORIZATION: Client's telephone conversation.
PURPOSE: Determine freeze-thaw resistance and pH.
TEST DATES: 10/29/91 to 11/06/91.
PROCEDURE: pH was determined by glass electrode in
accordance with ASTM E-70. Freeze-thaw cycles were run in accordance
with ASTM D-2243.
CUSTOMER: Advanced Protective Products
DATE: November 2, 2011
IMR MSL Report Number 32997
REPORTED AS: XRD EVALUATION OF UNTREATED AND TREATED
AREAS WITH A RED METAL PRIMER
SAMPLES RECEIVED & ANALYSIS REQUESTED:
One (1) quart of “Rust Knockout” red metal primer was received for XRD
evaluation. IMR was asked to apply the primer on a rusted iron coupon
and compare the untreated area and the treated area using XRD technique.
ANALYTICAL PROCEDURE
X-Ray Diffraction Spectroscopy (XRD): This technique generates a
diffraction pattern and matches unique peaks to known standards using a
computer-based library in order to determine present compounds by their
crystalline structure.
RESULTS
The photograph of the iron coupon showing the untreated and treated
areas is attached as Figure 1.
The XRD spectra of the rusted area and painted area are displayed in
Figures 2 and 3. The XRD Diffractograms were generated at 2Th/Th Start:
10.0 – End: 80.0; scan speed: 0.5 at increments of 0.02, generator at 40 kV;
40 mA, using the Bruker AXS D8 Discover X-Ray diffractometer. The
patterns for the rust and painted areas (each phase found) were
determined by the ICDD (Information Center for Diffraction Data) and
Plus Evaluation (EVA) software.
The phases of iron oxide hydroxide [FeO(OH)] were detected on the rusted
area by XRD. After the application of “Rust Knockout” red metal primer,
the iron oxide hydroxide [FeO(OH)] phases were not detected by XRD due
to the action of the water base rust converter primer.
The phases identified for the rusted and painted areas are attached in
TABLE I.

SUBJECT: One paint submitted and identified by the
client as: AH2377 (red)
AUTHORIZATION: Client's letter dated September 14,
1989.
PURPOSE: To determine the freeze thaw resistance of
the paint
PROCEDURE: In accordance: with ASTM D-1211 modified.
Freeze thaw resistance was determined by subjecting
coated steel panels (5) to 15 cycles of 1 hour at -20oF, 1 hour at -5oF
and 1/2 hour at room temperature 70-75oF.
RESULTS: No change after 15 cycles.
