The coating was applied to the substrate sample bybrush by Ship-2-Shore representatives, Zoran Culin and Erik Bergvinson, who thenwitnessed the samples’ placement inside the Q-fog chamber before commencing the saltfog test.TEST SOLUTION PREPARATION:The test solution was prepared using 5 1 parts by mass of sodium chloride (NaCl) and95 parts of water. Impurity content in the sodium chloride was confirmed to be below thelimits given in ASTM B117, Section 8. Adjustment to solution pH was made using analyticalgrade sodium hydroxide and/or analytical grade hydrochloric acid.This report shall not be reproduced, except in full, without the written approval of Powertech Labs, Inc.Page 1 of 12TR02785.01-05R0

Collected solution pH remained near-neutral, but particulardaily measurements were marginally below the specified pH range (minimum values of6.0-6.3 versus 6.5-7.2). As per ASTM B117, reservoir pH adjustments were made tocompensate when the collected solution pH was found to be out of specified range.TEST RESULTS:Test results relate only to the item tested. No acceptance criteria were provided by theclient. Photographs of the specimens before and during testing are provided below inFigures 2.The specimens did not sustain corrosion, pitting, or metal loss after exposures of up to336 hours. Evidence of corrosion was observed on the Float Coat V.1 specimen (Figure 2D) after exposures of approximately 500 hours and longer.This report shall not be reproduced, except in full, without the written approval of Powertech Labs, Inc.Page 4 of 12TR02785.01-05R0
