Versacor TF uses a 1.5-mil Urethane top coat and Versacor HF uses a 3.0-mil-thick top coat. Reverse Side Protection 1.5 or 3.0 mil nominal Arctic Ice Urethane* *Other combinations of Interior Top Coat Finish for increased reverse side protection are available. On CENTRIA Profile Series panels, with a Versacor Ultra coating system, an optional 3-mil-thick Versacor Barrier Coat may be applied to the interior liner of the metal substrate. A wash coat, Urethane top coat (Arctic Ice standard) or a Polyester top coat (Arctic Ice standard) are applied over the barrier coat. As more exterior walls are designed with open rainscreen wall systems, this additional coating protects against corrosion from the interior and at lap conditions. 3
Why Perform Accelerated Paint Coating Testing? Accelerated weathering simulates damaging effects of long-term outdoor exposure of coatings by exposing test samples to varying conditions under laboratory control. Numerous tests explore the performance of coatings in conditions of extreme ultraviolet radiation, moisture, heat, cleaning and corrosive conditions. No direct correlation can be made between accelerated testing and actual outdoor exposure. However, insight into the long-term performance capabilities of coatings are gained by performance comparisons under the controlled conditions of accelerated testing compared to documented results of a coating s long-term outdoor exposure. CENTRIA utilizes Third-Party Verification of paint coating testing to assure quality performance of all available coatings. These tests include: Accelerated Weathering Salt Spray Testing Cyclic Corrosion Testing Humidity Testing Kesternich Testing QUICkER RESULTS Actual outdoor exposure is the best method to test the performance of coated metal products. However, real-time testing does not permit immediate examination of innovative or improved coating system formulas. Accelerated testing under laboratory conditions are an accepted alternative to actual exposure testing and are utilized to simulate long-term performance under a variety of conditions. Most coatings undergo outdoor exposure testing after they pass the accelerated tests. 4
Cyclic Corrosion Testing Purpose: To observe the performance of coatings subject to accelerated conditions of the cyclic corrosion/uv exposure: Salt Spray, duration 72 hrs Drying in air, duration 16 hrs UV A-340 nm, duration 80 hrs 12 cycles at 168 hrs/cycle Evaluation: Evaluation is performed every 336 hours or multiples thereof and after completion of testing. This evaluation must be done after the completion of the two-step (UV exposure and Salt Fog/Dry Exposure) cycles only. Methods used for specimen coating corrosion evaluation may include ASTM Test Methods D-610, D-714, and D-1654. ASTM D-4587 may also be used and references a number of other standards for evaluating the appearance change of the specimens. Many corrosion specifications today often call for exposing test specimens to a cyclic corrosion test procedure. Current research indicates that these tests give more realistic results than conventional salt spray because the relative corrosion rate, structure and morphology are similar to those seen in actual atmospheric exposures. These procedures typically consist of repetitive cycles of salt fog, high humidity and dry off at elevated temperature.

Abrasion Resistance Purpose: To assess, quantitatively, the abrasion resistance of the coatings. Evaluation: The amount of abrasive required to penetrate one mil of coating to the substrate is measured in liters to determine resistance per mil. The ability of an organic coating to resist abrasion is often tested by the Abrasion Resistance of Organic Coatings by Falling Sand Abrasive ASTM D-968-93. In this test, an abrasive material (silica sand or silicon carbide) is permitted to fall through a guide tube set at a specified height above a coated panel. The test results shown here are the total liters required to penetrate the entire coating thickness to the substrate. COMPARATIVE RESULTS Liters of Falling Sand Good Best Coating Type 100 200 300 400 500 600 700 800 PVDF Duragard Plus 6
Salt Spray Testing Purpose: To study the creepage resistance of flawed coatings under accelerated conditions of the corrosive environment. Evaluation: After 2000 hours, coating defects are assessed per ASTM D-1654, Procedure A at Scribe, ASTM D-610 and ASTM D-714 for the field of the sample panel. Salt Spray Testing provides a controlled accelerated corrosive environment to evaluate the relative corrosion resistance of the coating or part itself. Sample panels are placed inside a chamber and exposed continually for a specified period then evaluated for resistance to rust in accordance with ASTM B-117-85. COMPARATIVE RESULTS Scribe Protected Edge Blistering After 2000 Hours Coating Type Very Few Few Medium Med. Dense Dense PVDF Duragard Plus No Blistering No Blistering 7
Humidity Testing Purpose: To evaluate the relative corrosion resistance of the coating in a controlled environment. Evaluation: Performance is evaluated by a pass or fail method. The coating passes if there is no evidence of water-related failure during the time period required. Humidity Testing per ASTM D-2247-97 provides a controlled accelerated corrosive environment to evaluate the relative corrosion resistance of the coating. Understanding how well a coating resists water is important because moisture is often a cause of coating degradation. Humidity Testing is performed in a closed chamber environment at 100 F (38 C) at 100% relative humidity. Sample panels are placed inside the chamber and exposed continually for a specified period then evaluated for resistance to rust. Time length of the test is not specified by ASTM.

kesternich Testing Purpose: The Kesternich test simulates the detrimental effects of acid rain on a coating. Evaluation: After 30 cycles, samples must exhibit no significant blistering, color change or loss of adhesion to pass. The test calls for dissolving sulfuric dioxide in distilled water, creating sulfuric acid. The chamber is heated for 8 hours at 100% relative humidity. After 8 hours, the chamber is vented of excess sulfuric dioxide and returns to room temperature. The cycle is repeated every day for 30 cycles.

Accelerated Weathering Purpose: To demonstrate the effect of light on a coating, The Accelerated Weathering test utilizes different light bulb types to simulate sunlight. Evaluation: After 2000 hours, paint specimens are rated for chalk and fade. In this test, paint samples are placed in a QUV Accelerated Weatherometer with either an A-Bulb or B-Bulb, in accordance with ASTM D-4587 and G-154, for 2000 Hours. Tested samples are compared to the control sample to rate chalk and fade.
