Epoxy Zinc-Rich Primers for
Civil Works Applications
by
Timothy D. Race
The Corps of Engineers' specification for epoxy zinc-rich primer designates E-303d for application as a primer for topcoats. However, E-303d has a relatively high volatile organic compound (VOC) content, which will likely be limited by a forthcoming U.S. Environ mental Protection Agency (USEPA) national rule for VOC content of architectural and industrial main tenance coatings. A possible alternative to E-303d is an epoxy coating enhanced with a zinc-rich primer. This research evaluated the performance and potential utility of commercially available zinc-rich epoxy primers as replacements for E-303d.
Ten commercially available low-VOC epoxy zinc-rich primers were evaluated using laboratory tests designed to simulate three exposure environments: (1) fresh water immersion, (2) salt water immersion, and (3) atmospheric weathering. Overall, the commercial primers performed nearly as well as E-303d. This study found that multiple low-VOC commercial equivalents to E-303d are available for each exposure environment, and recommended field tests of the most promising primers.
This study was conducted for The Electrical and Mechanical Branch, Engineering Division, Directorate of Civil Works, Headquarters, U.S. Army Corps of Engineers (HQUSACE) under "Civil Works Investigations and Studies" (CWIS) Work Unit 31205, "Developing High Performance Coatings."

1 Introduction
Background
The Corps of Engineers currently uses its own specification for epoxy zinc-rich primer (E-303d), which is applied as a primer for topcoats Mil-P-24441 Paint, Epoxy-Polyamide and SSPC Paint Specification No. 16, Coal Tar Epoxy-Polyamide Black (or Dark Red) Paint (1991). These coating systems are used for a variety of applications including fresh and salt water immersion and atmospheric weathering.
However, E-303d has a relatively high volatile organic compound (VOC) content, typi cally 500-600 grams per liter as applied. The U.S. Environmental Protection Agency (EPA) will propose a national rule for VOC content of architectural and industrial maintenance coatings. The proposed VOC content requirement for industrial main tenance primers will likely be 350 grams per liter. When this national rule is imple mented in 1996, the Corps will no longer be able to apply E-303d. Therefore, an appro priate replacement is needed.
Objective
The objective of this research was to evaluate the performance and potential utility of commercially available epoxy zinc-rich primers as replacements for E-303d.
Approach
Ten commercially available low-VOC epoxy zinc-rich primer coatings were applied to steel test plates and topcoated with MIL-P-24441 and SSPC Paint 16. The test coatings were evaluated using laboratory tests designed to simulate three exposure environments, fresh and salt water immersion and atmospheric weathering. Test panels were evaluated periodically for degree of rusting, blistering, and rust under cutting. Standard Corps of Engineers epoxy systems were used as experimental controls.
Scope
This study was limited to a laboratory evaluation. Laboratory test exposures can be used to measure the relative performance levels of different coatings. However, care should be taken not to extrapolate the results of laboratory experiments to actual field performance. Field tests should be conducted to fully validate the utility of any coating technology. The results contained in this report do not represent an endorsement of specific products or manufacturers.
Mode of Technology Transfer
It is recommended that the information contained in this report be used as a basis for further study to determine, on a preliminary basis, the suitability of low-VOC commer cial epoxy zinc-rich primers as replacements for Corps of Engineers specification E-303d.
Test Coating Application
Ten commercial epoxy zinc-rich primers were mixed and applied in accordance with the manufacturers recommendations. Each primer was topcoated with MIL-P-24441 (Formula 152, Type IV) and SSPC Paint 16 per the requirements of coating systems 21-A-Z and 6-A-Z respectively. Corps of Engineers Paint Systems Number 6-A-Z and 21-A-Z were used as experimental controls. System 6-A-Z consists of two coats of E-303d primer and two coats of SSPC Paint 16, coal tar epoxy coating. System 21-A-Z consists of two coats of E-303d primer and two coats of MIL-P-24441, epoxy-polyamide topcoat. Coatings were spray applied to SP 1 and SP 5 cleaned hot rolled commercial grade carbon steel test panels measuring 3 x 6 x 0.125 in.* Table 1 lists the test coatings.

The dry film coating thickness of the test and control coatings were measured in accordance to ASTM D 1186, Standard Test Methods for, Nondestructive Measurement of Dry Film Thickness of Nonmagnetic Coatings Applied to Ferrous Base (1987). The average dry film thicknesses for each coating system are listed in Table 2.
Selection of Test Methods
Laboratory test methods were selected that simulate the expected service environ ments for epoxy zinc-rich coated steel, including fresh and salt water immersion and atmospheric weathering. Fresh and salt water immersion are readily replicated in the laboratory using aerated tap water and synthetic sea water. Atmospheric exposure may be simulated using an accelerated test method that cycles the test panels through alternating ultraviolet radiation and salt fog exposures.

Salt Water Immersion
Six test panels of each of the control and experimental systems were immersed in synthetic sea water prepared in accordance with section 7, Salt Solution, of ASTM B 117 Standard Test Method of Salt Spray (Fog) Testing (1990) for a period of 120 days. All test panels were scribed prior to immersion exposing an area approximately one-eighth by 2 in. Test panels were evaluated after 7, 60, and 120 days for degree of rusting and blistering in accordance with ASTM D 610 Standard Method for Evaluating Degree of Rusting on Painted Surfaces (1989) and ASTM D 714 Standard Test Method for Evaluating Degree of Blistering of Paints (1987). Degree of undercutting was measured after 120 days in accordance with ASTM D 1654 Standard Method for Evaluation of Painted or Coated Specimens Subjected to Corrosive Environments (1992).
Fresh Water Immersion
The same tests were performed for panels immersed in fresh tap water as for salt water immersion.
Cyclic Corrosion Weathering
Six scribed test panels of each control and test system were subjected to 16 weeks of cyclic corrosion testing. The test cycle consisted of 1 week in an ultraviolet condensa tion cabinet per ASTM G 53 Standard Practice for Operating Light- and Water-Exposure Apparatus (Fluorescent UV-Condensation Type) for Exposure of Nonmetallic Materials (1991) using UV-A bulbs (4 hours UV at 60 °C, 4 hours condensation at 50 °C) followed by 1 week of alternating salt spray at 30 °C (4.0 g/L ammonium sulfate, 0.5 g/L sodium chloride) for 1 hour followed by 1 hour of forced air drying at 40 °C (modified ASTM G 85 Annex A5.). The test panels were evaluated for degree of rusting and blistering after 1, 2, 4, 8, 12, and 16 weeks. Degree of undercutting was measured after 16 weeks.
Salt Water Immersion
Degree of blistering adjacent to the scribe and rusting were determined for the test and control coatings after 7, 60, and 120 days in salt water immersion. Rust under cutting at the scribe was measured after 120 days. The results are summarized in Table 3. The rust undercutting data has been converted to integer values from zero to 10, as described in ASTM D 1654, with the exception that the maximum rather than the mean scribe creepage is used. The blistering data is similarly converted by taking the average of the sum of the blister size and the converted blister density. The converted blister density is an integer value from zero to 10 with very dense blistering equal to zero and no blistering equal to 10. Rust, blister, and undercut values are the averages of six test specimens for each coating system. The composite score, shown in the last column, is the sum of numerical rust, blister, and undercut ratings, at 120 days. A composite score of 30 corresponds to no coating degradation. The raw data for the salt water immersion tests are presented in the Appendix to this report.
Early blistering adjacent to the scribe is a good indicator of poor long-term perfor mance for salt water immersion applications. In general, the commercial epoxy zinc-rich primer systems show good resistance to blistering in salt water immersion. Coat ing film defects resulting from damage during handling and erection are inevitable. Degree of rust undercutting measured in conjunction with coating film defects is an important measure of long-term coating performance. None of the coating systems evaluated exhibited undercutting at the scribe.
Both of the control systems showed no degradation after 120 days and had perfect com posite scores of 30. Of the 20 test systems (10 primers each with two different top coats), 16 had perfect composite scores. Four of the commercial primers topcoated with MIL-P-24441exhibited blistering adjacent to the scribe. All of the primers topcoated with SSPC Paint No. 16 had perfect scores. In a previous study, SSPC Paint No. 16 without a zinc-rich primer, had a perfect composite score of 30 after 112 days of salt water immersion (Race and Boy 1995). This result indicates that SSPC Paint No. 16 provides excellent corrosion resistance based on its barrier properties alone.

Table 3. 120-day salt water immersion test results.Not surprisingly then, all of the zinc-rich primed test systems evaluated in this study have excellent corrosion resistance. Paint System 21 (MIL-P-24441 Formulas 150 and 152) was also evaluated in the previous study. This system showed both blistering (4.0) and undercutting (8.5) at the scribe with a composite score of just 22.5 after 112-days in salt water immersion. All of the commercial primers with the MIL-P-24441 topcoat performed better in this study than MIL-P-24441 without the zinc-rich primer in the previous study. Each primer prevented undercutting at the scribe whereas unprimed MIL-P-24441 did exhibit undercutting at the scribe. Not surprisingly, zinc-rich primed systems with MIL-P-24441 topcoat, do not perform as well as zinc primed systems topcoated with SSPC Paint No. 16.
Fresh Water Immersion
Degree of rusting and blistering were determined for the test and control coatings after 7, 60, and 120 days in fresh water immersion. Rust undercutting was measured after 120 days. The results are shown in Table 4. The raw data is presented in the Appendix to this report. The composite score for each test panel is presented in the last column of the table.

Table 4. 120-day fresh water immersion results.
In general the commercial primer systems perform well in fresh water immersion. None of the test coatings or controls exhibited rust undercutting at the scribe at the completion of the 120-day test period. One primer showed blistering adjacent to the scribe when topcoated with both the standard coatings. Notably this primer topcoated with MIL-P-24441 also blistered in salt water immersion.
Cyclic Corrosion Weathering
Test coatings and controls were evaluated for 16 weeks in a cyclic salt fog/UVCON corrosion cycle designed to simulate the long-term effects of atmospheric weathering. Test panels were evaluated for rusting and blistering after 1, 2, 4, 8, 12, and 16 weeks. Rust undercutting at the scribe was measured at the completion of the 16 week test. The results are summarized in Table 5. The Appendix to this report lists the raw data for the cyclic corrosion testing.

Table 5. 112-day cyclic corrosion weathering.
Cyclic corrosion testing was used to predict the relative performance of the control and test coatings in atmospheric weathering. All of the test panels had perfect blister and rust ratings at the completion of the cyclic corrosion test. The two controls and 10 of the commercial systems did not exhibit undercutting at the scribe and had perfect composite scores. Of the 10 commercial systems with perfect composite scores, seven were topcoated with MIL-P-24441 and three with SSPC Paint No. 16. All the primers evaluated have equal or better performance when topcoated with MIL-P-24441 compared to the same primer topcoated with SSPC Paint No. 16. The average com posite scores for commercial primers topcoated with MIL-P-24441 and SSPC Paint No. 16 are 29.8 and 28.4 respectively.
Cyclic corrosion resistance of paint System 21 (MIL-P-24441 Formulas 150 and 152) and SSPC Paint No. 16 were evaluated in a previous study. SSPC Paint No. 16 exhibited blistering (9.3) and undercutting (5.8) adjacent to the scribe after 14 weeks of testing. System 21 also showed blistering (3.7) and undercutting (4.3). The com posite scores for Paint No. 16 and System 21 were 25.1 and 18.1 respectively. All of the commercial primer systems performed better in this study than the unprimed system analogs in the previous study. The commercial primers eliminate blistering and reduce undercutting at the scribe.
This research evaluated the performance and potential utility of commercially avail able low-VOC epoxy zinc-rich primers as replacements for E-303d, which is used with two different topcoats, MIL-P-24441 and SSPC Paint No. 16. Each commercial primer was topcoated with these materials and exposed in fresh and salt water immersion and cyclic corrosion weathering tests. Performance was measured in terms of rusting, blistering, and undercutting and was compared to the standard coating systems.
For the salt water immersion exposure, commercial primers topcoated with SSPC Paint No. 16 were generally superior to those topcoated with MIL-P-24441. All of the commercial primers topcoated with SSPC Paint No. 16 performed as well as E-303d topcoated with SSPC Paint No. 16. For short term salt water exposures, the commer cial analogs perform as well as E-303d topcoated with SSPC Paint No. 16, and with some exceptions, as well as E-303 topcoated with MIL-P-24441.
In short-term fresh water immersion exposures, all but one of the commercial primers topcoated with SSPC Paint No. 16 and MIL-P-24441 performed as well as E-303d topcoated with these materials.
The E-303d primed systems were slightly superior to most of the commercial primer systems in the cyclic corrosion weathering test. Three of the commercial primers had performance equivalent to the E-303d systems. The commercial systems performed better in this test with topcoat MIL-P-24441 than with SSPC Paint No. 16. Commer cial primer systems performed better than the unprimed system analogs evaluated for cyclic corrosion weathering resistance in a previous study.
Two of the 10 commercial primers performed as well as E-303d in all of the test exposures. Overall the commercial primers performed nearly as well as E-303d. Multiple low-VOC commercial equivalents to E-303d are available for each exposure environment.
Field tests of the most promising primers (Amercoat 68HS, Carboline 858) are recom mended. Tests should include fresh and salt water immersion and atmospheric weath ering. The performance of each of the primers evaluated in this study should be further studied using commercially available epoxy topcoats from the respective manu facturers of each primer, instead of MIL-P-24441. The use of MIL-P-24441 and othermilitary specification paints has been restricted by the Corps of Engineers in response to recent procurement reform initiatives. For this reason, a commercial equivalent to MIL-P-24441 is needed. The Corps should specify a coating system comprised of epoxy zinc-rich primer and epoxy topcoat with a defined level of performance. The results of this study and future laboratory and field tests could provide a basis for specifying the performance of this system.
