Test Methods:
Surface Resistance : Initial Surface resistance of the coupons was taken per CEPS-0002, with a 1in2 co-probe using
2kg of force.
Adhesion: Adhesion testing per ASTM D3359 Method B was taken initially and also after fluid immersion.
Fluid Resistance
The following fluids and dwell conditions were evaluated:
The samples were placed upright in a container and fully submerged in the fluids. The container was sealed and stored
at room temperature for 72 hours.
Following the dwell the sample coupons were removed from the fluid rinsed with de-ionized water and physically dried
using an absorbent cloth. The dried sample coupons were then evaluated for:
Surface Resistance – CEPS-0002
Visual Inspection – Evaluate the presence of any wrinkling, sagging, bubbling, streaking, and solvent popping or
other irregularities.
Solvent Rub Resistance – 50 double wipes with MEK using a two-pound ball-peen hammer without exposing the
substrate.
Adhesion – Cross hatch adhesion was performed per ASTM D3359-2.
Corrosion
The samples were placed in a neutral Salt Fog environment per ASTM B117. They were observed after 96 hrs and 504
hrs. The samples were rinsed with de-ionized water to remove some of the salt The samples were visually inspected for
the presence of any blistering or peeling.
Abrasion Resistance
Samples were subject to Taber Abrasion per ASTM D 4060. The weight of the sample coupons were recorded before
and after 1000 cycles on the taber abrader with 500gm CS-10 wheels.

Conclusions:
Fluid Resistance: All samples of CHO-SHIELD ® 2001, CHO-SHIELD ® 2002 and CHO-SHIELD ® 2003 (including all cure
schedules and regardless of substrate) demonstrated no change in surface resistance following the 72 hour room
temperature dwell in hydraulic fluid and lubrication oil. All samples yielded pre-immersion and post-immersion fluid
immersion surface resistivity’s of <0.1 Ω/Sq. All CHO-SHIELD 2000 series coatings have a post-immersion* surface
resistivity of <0.5 Ω/Sq following 72 hour room temperature dwell in JP-8 fluid.
*JP-8 values measured 6 days post fluid immersion.
Post Exposure Surface Characteristics: All samples of CHO-SHIELD ® 2000 series coatings passed visual
inspection and were free of any wrinkling, sagging, bubbling, streaking, solvent popping or other irregularities post fluid
immersion.
Adhesion: No changes occurred in the adhesion strength of any of the coatings regardless of the substrate. A
rating of 5B (0% area removed) was observed from the cross-hatch adhesion test before and after fluid immersions.
Corrosion: CHO-SHIELD ® 2001 and CHO-SHIELD ® 2003 had no substrate (6061-T6 Al) degradation after 500 hours
in a neutral salt fog environment.
CHO-SHIELD ® 2002 designed for use on composite substrates was evaluated on G10 (fiberglass epoxy) at 500 hours with
no substrate degradation. It was also tested on a 6061-t6 Al substrate at 100 hours with no visible degradation.
See Appendix for pictures of CHO-SHIELD 2001, 2002, and 2003 corrosion plaques.
Abrasion Resistance: CHO-SHIELD ® 2000 series coatings provide high abrasion resistance. At both cure 1 and 2
CHO-SHIELD® 2001 and CHO-SHIELD ® 2002 both yielded weight loss of <60mg. At cure 1 and 2 CHO-SHIELD ® 2003
yielded weight loss of <90mg.
Summary:
The new CHO-SHIELD ® 2000 Series coating formulations with supplier recommended raw material replacements
perform equivalent to the original CHO-SHIELD ® 2000 Series formulations with the original raw materials in Chomerics’
internal qualification and conformance testing.

Salt Fog Corrosion Results
Coupons were placed in a neutral salt fog environment for 500 hours to evaluate the effect of the replacement
raw materials on the corrosion properties. The edge of each coupon was coated with wax to prevent corrosion
from beginning on the edges. Three samples per cure were conditioned; each cure is displayed in their
respective rows ( i.e. cure 1= row 1, cure 2= row 2, cure 3= row 3). Samples are displayed as scratched (1 inch
scratch through coating before conditioning) and non-scratched. The coupons were inspected for blistering or
peeling.
