3.3 Pinhole detection

Pinhole detection was performed on the coated test panel before the tank exposure. The detection was carried out by means of an Elcometer 269 Pinhole detector at 90 volts. The results from the pinhole detection are presented in Table 6.

4 EXPOSURE The exposure in the simulated ballast wave, condensation chamber and heating cabinet was carried out according to the IMO Performance Standard for Protective Coatings /1/. The exposure was started 2008-06-15 and terminated 2009-12-11.

5 PRODUCT IDENTIFICATION

The density of each component of the coating system as described in Table 3 was determined by means of an Erichsen Mod. 290/1 pyknometer based on ISO 2811-1 /5/. Furthermore, IR spectra of all components were recorded on a Nicolet Protégé 460 FT-IR spectrometer. The results from the paint identification are listed in Table 5 and Appendix B respectively.

Minimum 6.8 9) Number of test specimen per panel in accordance with IACS Rec. No. 101 /7/ 10) Adhesion tests were carried out with a DeFlesko PosiTest AT adhesion tester. Dollies with 20 mm diameter were used. The coating surface and dollies were softly grinded with FEPA P#320 SiC paper and rinsed with technical alcohol. The dollies were glued to the coated surface with 3M DP410 adhesive. The curing of the adhesive was carried out according to manufacturer’s recommendations. A whole saw was employed to carefully cut through the coating down to bare steel before pulling off the dollies.

12) “Assess loss of adhesion at the artificial holiday by using a sharp knife to make two cuts through the coating to the substrates, intersection at the holiday. With the point of the knife, attempt to lift and peel back the coating from around the holiday. Record whether the adhesion of the coating to the substrate has been reduced and the approximate distance, in millimetres, that the coating can be peeled.” (From ISO 15711:2003 /5/) Additionally IACS interpretation of IMO PSPC: Repeat the cutting and lifting all around the artificial holiday to find the maximum loss of adhesion. Disbonding from artificial holiday can be either loss of adhesion to the steel substrate or between the shop primer and the epoxy coating and shall be less than 8 mm for epoxy based systems to be acceptable (compatibility test). Cohesive adhesion failure in the shop primer is not to be included as part of the loss of adhesion. (From IACS Rec. No. 101 /7/) 13) Exposure time: 119 days submerged in natural seawater during total 180 days of cyclic exposure as defined in /1/ Utilisation factor: 0.8

Consumption rate for Zn-anodes: 11.3 kg/A year

Carefully remove any loose coating using a knife blade held at an angle, positioning the blade at the coating/ substrate interface and lifting the coating away from the substrate.” (From ISO 4628-8:2005, section 5.3.1 /10/) Addionally IACS interpretation: Undercutting from scribe can be either corrosion of the steel substrate or delamination between the shop primer and the epoxy coating (compatibility test). For PSPC maximum width is used (MSC.215(82), Appendix 1, section 2.2.6). The average of three maximum records of three panels with scribe is used for acceptance. Cohesive adhesion failure in the shop primer is not to be included as part of the delamination. (From IACS Rec. No. 101 /7/)
