EnduraGuard™ is the latest breakthrough from Pioneer Metal Finishing that works particularly well on
die castings and wrought alloys. Ask about EnduraGuard™ for extreme corrosion protection needs. EnduraGuard™ has great performance properties like:
• Endures 1000+ hours of salt spray with a crosshatch test*
• Guards against Acid and Alkaline attacks
• Fights filiform corrosion
• Improves appearance and has a non-aging finish
• Unmatched color consistency
*Results may vary depending upon alloy constituents of casting and actual conditions
COMPARATIVE TESTING OF CONVENTIONAL E-COAT VS ENDURAGUARD™
Test 1: Acid Test
One
E-coated part and one EnduraGuard™ treated part was placed in an acidic
solution consisting of 13% Sulfuric Acid by volume. The parts were left
in the solution for a total of 80 hours at room temperature. After
exposure, the parts were rinsed and dried for inspection. The following
photos illustrate that the
E-coat part had large areas of peeling as well as severe areas of corrosion, particularly on the inside of
the part.
Test 2: Corrosion Resistance Test (Salt spray test with a crosshatch)
The
salt spray test was done according to ASTM B117. The E-Coated part
shows severe corrosion, particularly on the inside of the part. The
crosshatched area shows creeping of the cross, indicating corrosion. The
part with the EnduraGuard™ treatment shows small areas of corrosion
where the part was racked during coating. The rest of the part showed no
signs of corrosion. The crosshatched area shows minor corrosion, but no
creeping of the cross, indicating no spreading of the corroded area.
Test 3: Time lapse from 200 hours to over 3200 hours
In a different application, EnduraGuard™ held up over 3200 hours of salt spray with a crosshatch test.
The photos above illustrate how EnduraGuard™ resisted corrosion.
SUMMARY
The tests performed show the following results:
Coating Hardenss: EnduraGuard™ gives significant improvement compared to conventional E-coating.
Acid Resistance: EnduraGuard™ showed significant improvement compared to conventional E-coating.
Corrosion Resistance: EnduraGuard™ gives a significant improvement in corrosion resistance
compared to conventional E-coating. Samples processed in the laboratory
indicate corrosion resistance in excess of 1,000 hours of salt spray.
