2 1. SCOPE: 1.1 Cleaning, Surface Preparation and Painting Requirements for Underwater Hulls to support the application of non-toxic foul-release coating system Intersleek 970 (International Paint) for testing and evaluation purposes. 1.2 RISK STATEMENT: Risk for installation. If proper surface preparation and application procedures are not adhered to, coating system failure can occur within 3-6 months Excessive airborne dust during coating application and post-application drying can result in significant surface contamination, possibly resulting in inter-coat adhesive failure during service Failure to protect areas adjacent to surfaces being coated by the Intersleek system, e.g., through inadequate masking, can result in contamination of surrounding surfaces, resulting in failure of the coatings applied in those areas. This includes areas with exposed bare metal, primer, or intermediate coats that are to be overcoated. Contamination of such surfaces awaiting (re)coating can cause failure or flaws (e.g., fish eyes) in the subsequent coat Compared to many other coatings, Intersleek 900 overspray is light and floats easily in air its behavior in this regard is comparable to commercial polyurethane coating systems This coating system should be applied using the minimum number of zones possible; in order to ensure optimum in-service coating performance, application in one zone is recommended. If it is necessary to apply the coating system using multiple zones, areas adjacent to the work zone (including adjacent zones) shall be carefully masked during application, in order to avoid failure of the coating at the boundaries between zones Maintenance operations conducted on structures coated with Intersleek e.g., cutting into the hull with welding equipment can adversely impact the performance of Intersleek, if the coating is not adequately reapplied and/or repaired. If repair of any part of the Intersleek coating system is required, contact the authorized on-site Navy technical representative for instructions Coating application outside of daylight hours is not encouraged. If it is found to be necessary, sufficient artificial light shall be provided prior to initiation of nighttime work. Inadequate lighting presents considerable risk of insufficient application to areas in shadow Risk for curing. If overcoat window timeframes are not adhered to, coating system failure is possible within the first 3 months of application If the PPI checkpoint criteria are met, the following table provides service life expectancy for the listed coating system: Coating System Life Expectancy: Area Surface Preparation Method Anticorrosive/Foul- Release Coating System Life Expectancy Underwater Hull (keel to top of boottop) Cleanliness Level: SSPC-SP-12 WJ-2/L: ultrahigh pressure waterjet; -or- SSPC-SP-10: abrasive blast International Intersleek 970 hull: BLUE topcoat / boottop: BLACK topcoat 5-7 years 2.

4 7. PAINTING REQUIREMENTS:. REFER TO CORE PPI EXCEPT FOR THE FOLLOWING NOTE: UNDERWATER SUBSTRUCTURES TO RECEIVE THIS COATING SYSTEM SHALL INCLUDE RUDDERS, STRUTS, FAIRWATERS, AND SEACHESTS.* PROPELLERS AND SHAFTS SHALL NOT RECEIVE THIS COATING SYSTEM (i.e., THEY WILL UNDERGO STANDARD PRESERVATION PROCEDURES, AS DETERMINED BY APPROPRIATE NAVY ACTIVITY). DIELECTRIC SHIELDS SHALL ONLY RECEIVE THIS COATING SYSTEM IF NO ADDITIONAL COST WILL BE INCURRED IN PRACTICE, WHAT THAT MEANS IS THAT THESE AREAS AROUND THE ANODE SHALL ONLY BE CONSIDERED FOR RECEIPT OF THIS COATING SYSTEM IF CAPASTIC SHIELD REPLACEMENT WOULD BE SCHEDULED UNDER NORMAL CIRCUMSTANCES. DIELECTRIC SHIELDS DETERMINED TO BE IN ACCEPTABLE CONDITION, AND THUS SCHEDULED FOR LITTLE (TOUCH-UP) OR NO MAINTENANCE UNDER NORMAL CIRCUMSTANCES, SHALL NOT RECEIVE THIS COATING SYSTEM. *FOR RECESSED SURFACES NOT ACCESSIBLE TO IN-SERVICE DIVER INSPECTION OR MAINTENANCE, USE OF TYPE II MIL-PRF COATINGS SHALL BE RETAINED. THESE SPACES SHALL BE SEALED OFF DURING APPLICATION OF INTERSLEEK TO ADJACENT EXTERIOR SURFACES, TO PREVENT CONTAMINATION OF THE ABLATIVE ANTIFOULING COATING BY INTERSLEEK OVERSPRAY. NOTE: FOR PROPULSION SHAFT OUTBOARD BEARING VOIDS; EXISTING TYPE II MIL-PRF COATINGS MAY BE RETAINED/ REPLACED ON INTERNAL SURFACES OF STRUT AND STERN IN WAY OF OUTBOARD BEARINGS. FILL THE BEARING VOIDS WITH CORROSION PREVENTIVE COMPOUND MIL-C CLASS 1 AFTER EACH BEARING SHELL INSTALLATION The coating system to be applied is the International Intersleek 970 system that is specified in Appendix Coating application specialists selected to apply the coating shall be experienced in the application of the Intersleek 970 coating system, or shall receive training, prior to commencement of work. Training information and materials shall be provided by the coating manufacturer, and approved by the on-site Navy representative All spray equipment shall be ascertained to be well cleaned before each use, with no paint residue from previous work. All filters must be thoroughly stripped and washed. It is recommended that a dedicated spray pump be used for application of Intersleek. New spray lines shall be used exclusively for applications of Intersleek 731 and Intersleek 970, and these lines shall then be reserved solely for use with silicone paints. The use of pole guns during application of Intersleek 731 and Intersleek 970 is not permitted on vertical sides; where their use is necessary (e.g., on flat bottoms), the length of the pole must not exceed 40 inches Because of the serious contamination risk posed by airborne dust, any and all spent grit blasting materials should be removed from the dock prior to the Intersleek application. Damping down of the dust-producing materials is an acceptable alternative, as long as continuous monitoring of conditions is maintained in order to prevent condensation of dust on the surface being coated. Full containment of the coating area shall be maintained during Intersleek application, to prevent introduction of airborne contaminants To maintain proper surface conditions after completion of the surface preparation, checkpoint methods such as use of dehumidification equipment, environmental enclosures, and surveillance/monitoring of the prepared surface should be employed. Other than the exception noted in , coating application should start within 4 hours of acceptance of the condition of the cleaned surface. If coating application has not been started within this 4 hour period, the surface preparation checkpoint (with the exception of surface profile) will be repeated When ultra high pressure waterjet blasting is exclusively used for surface preparation, application of the primer coat should start within 6 hours of completion of surface preparation, in accordance with of NAVSEA Standard Instruction (FY-10) If, prior to their (re)coating, surfaces are not protected from airborne contaminants e.g., overspray from coating of the freeboard these surfaces shall be washed with freshwater to remove the contamination prior to commencement of (re)coating Coating application should take place during daylight hours. If this is not possible, adequate artificial lighting shall be provided prior to initiation of nighttime work General: Mix ratios, pot life, overcoat windows, cure times, and overspray control require rigorous attention for foul-release coatings. Carefully follow the requirements in the Manufacturer s ASTM F-718 sheets for UWH T&E of Intersleek 970 PPI 4

5 each coat (ref 2.c). While rigorous attention to all the overcoat windows is critical, it is especially so for overcoat of the second (anticorrosive) coat with the third coat (Intersleek 731 tie coat). NOTE: SOME OF THE COMPONENTS OF THE INTERSLEEK 731 TIE COAT AND INTERSLEEK 970 FINISH ARE WATER-THIN (i.e., OF LOW VISCOSITY), AND SHOULD BE HANDLED CAREFULLY TO AVOID ACCIDENTAL SPILLAGE DURING POURING AND MIXING PROTECTING ADJACENT WORK SPACES: Control and contain overspray using appropriate means and practices (masking, use of tenting or other enclosures, etc.). Contamination of surfaces in work spaces adjacent to the immediate work space with foul-release coating overspray (Intersleek 731 tie coat or Intersleek 970 topcoat) may cause failure of coatings being applied in those nearby spaces During the application of the Intersleek 970 system, areas adjacent to the application shall be protected by masking. The recommended masking material is 3M Polyester Tape # Prior to application of the second coat (Step ) of the Intersleek 970 system, the areas adjacent to the section to be coated with the Intersleek 970 system should be masked off For the boottop, and the adjacent areas above and below it, masking in multiple steps is required: The area above the boottop shall be masked for 6 9 feet, prior to application of the second coat (Step ). This can also act as the antifouling line cut-in After application and drying of the third coat (Step ), the boottop shall be completely masked, prior to application of the fourth coat (Step , Intersleek 970) to the hull After application and drying of the fourth coat on the hull (blue Intersleek 970), the masking shall be removed from the boottop, while ensuring that the freeboard surface remains masked. To protect the dried blue Intersleek 970 finish on the hull, it shall be masked in the same fashion as the boottop (see Step ). Once it is ensured that freeboard and hull are adequately masked, the fourth coating shall be applied to the boottop (Step , Intersleek 970 BLACK) To avoid overspray contamination onto the boottop and/or freeboard areas of the structure, when applying the Intersleek 970 system, paint must not be sprayed in an upwards direction towards the top of the masked area If repair of dried Intersleek is necessary, a special tape should be used to adhere plastic masking sheet to the surrounding dried Intersleek 970 top coat. The following tapes have been shown to be suitable for this purpose: 1) PPI SP-459, manufactured and supplied by PPI Adhesive Products Corp.; or 2) PPI SP-510, manufactured and supplied by PPI Adhesive Products Corp.; or 3) Mold Release Tape, 3M-06363#249 (2 in. x 6 in.), supplied by 3M Co Before application of the second coat of Intergard 264, painting of the topside should be completed. Care should be taken to avoid excessive overlap of the topside system onto the area to be coated with Intersleek, as wrinkling may occur when overcoated with the Intersleek system Prior to application of the second coat of Intergard 264, the adjacent area(s), i.e., boottop and/or freeboard, should be adequately masked in accordance with Step Coating application shall be continuous through completion of the area to be coated For each zone (section) of the ship structure undergoing coating: For each coat in the coating system, application shall be completed in the same workday i.e., application of entire first coat (primer, Intergard 264 red) in one day; application of entire second (Intergard 264 black) and third (Intersleek 731) coats in one and the same day; and except where noted below (Step and Step ), application of the entire fourth/final coat (International 970 blue) in one day The boottop will be coated in the same manner as the hull, except that the top coat will be Intersleek 970 BLACK For application of draft marks, the paint used will be Intersleek 970 WHITE.

6 SUBSTRATE (SURFACE) TEMPERATURE: The minimum acceptable substrate temperature at the time of application of the Intersleek 731 tie coat and the Intersleek 970 foul-release coat is 50 F and must be at least 5 F above the dew point SPECIAL NOTE ON MIXING: Consult the manufacturer s ASTM F-718, but also heed the following: No more than 15 minutes before a fresh fully mixed unit of Intersleek 731 or Intersleek 970 is required should part B be added to the can containing part A, and the two components thoroughly power-mixed For the Intersleek 970 foul-release coat, immediately before the final mix before use, part C should be opened and carefully added (under slow power-mixing) into the part A / part B mix. This component is moisture sensitive and should not be opened until just before it is needed. 7.3 RE-COAT PERIODS: The minimum and maximum re-coat periods for each coat are provided in the relevant ASTM F-718 documents (Ref. 2.c), NSI (maximum self-self recoat window for Intergard 264), and in this Section. Relative humidity (RH) shall be at least 40%; for lower RH, consult with on-site Navy representative before beginning application. These requirements must be adhered to for all parameters of coating surface preparation and application NOTE THAT THE RE-COAT PERIOD BETWEEN APPLICATION OF THE SECOND COAT (INTERGARD 264 BLACK) AND THE THIRD COAT (INTERSLEEK 731 LIGHT PINK) IS PARTICULARLY SHORT, RELATIVE TO THE OTHER RE-COAT APPLICATIONS IN THIS OVERALL COATING SYSTEM APPLICATION The preferred re-coat period for Intergard 264 is 7 days. If this period is exceeded a recoat period of up to 30 days in accordance with NSI may be used without a DFS. If conditions during the period of work require consideration of a re-coat period longer than 30 days, a DFS is required from the cognizant RMC. Because this coating system is being applied as part of a trial evaluation program, the on-site Navy representative will ensure that instructions are provided on how to proceed if the specified re-coat periods cannot be met Although the maximum re-coat time for application of Intersleek 970 over Intersleek 731 is 7 days, every effort should be made to carry out this application within 24 hours of the application of the Intersleek 731 tie coat, in order to minimize risk of in-service inter-coat adhesion failure due to excessive surface contamination at the Intersleek 731 surface. If coating inspection indicates significant surface contamination of Intersleek 731 prior to its re-coating, notify the on-site Navy representative Minimum time to flooding after completion of application of the Intersleek coating system is 24 hours at 70 F, and 36 hours at 60 F, for relative humidity greater than 40%. Under no circumstances should flooding take place less than 16 hours after completion of application. If temperatures lower than 60 F or relative humidity lower than 40% are encountered, notify Navy on-site representative for further instructions COATING OF FIRST COAT (INTERGARD 264 RED) BY SECOND COAT (INTERGARD 264 BLACK): Substrate Temperature: 70 F 80 F 90 F 100 F Intergard 264 (black) Min Max Min Max Min Max Min Max applied over 13 hrs. 7/30 days 10 hrs Intergard 264 (red). 30 days 7 hrs. 25 days 5 hrs. 21 days COATING OF SECOND COAT (INTERGARD 264 BLACK) BY THIRD COAT (INTERSLEEK 731 LIGHT PINK ) NOTE: Re-coat period much shorter for this application than for application of other coats.

Because the appropriate repair procedure is determined based on a number of factors, ensure that all application records are available for review by the Navy on-site representative and individuals designated by the Navy representative, to investigate the damage and/or provide assistance in the repair. 8. PRIMER (FIRST) COAT APPLICATION:... REFER TO CORE PPI and the following. 8.1 The primer coat shall be Intergard 264 (International Paints), and the color shall be RED. Follow the instructions of ASTM F-718 for this coating product (Ref. 2.c) Small runs and sags can be brushed out prior to cure Measure dry film thicknesses ( dft measurements) in accordance with Ref. 2.b of CORE PPI If the appearance of the coated surface indicates the presence of unreacted hardener/converter/curing agent ( amine bloom ), notify the Navy on-site representative immediately and await further instructions. 9. Not Applicable to this PPI 10. INTERMEDIATE COAT APPLICATIONS: REFER TO SECTION 10 OF CORE PPI, and the following For the coating system covered by this PPI, the following two coats are defined as intermediate coats: SECOND COAT: Intergard 264 (International Paints) anticorrosive coat. Follow the instructions of the ASTM F-718 document for this product Small sags and runs can be brushed out prior to application of third coat NOTE: Because of the very short re-coat period between this coat and the following coat (Step ), it will not be possible to obtain valid dry film thickness data, since this coat will not achieve a dry condition before application of the next coat THIRD (TIE) COAT: Intersleek 731 (International Paints) tie coat, color LIGHT PINK. Follow the instruction of the ASTM F-718 document for this product Small runs and sags can be attended to quickly (within 30 minutes of application), through use of a new, unused brush immersed in solvent (International GTA-007), then shaken to remove excess solvent prior to being used to lightly brush out the defects. Once the Intersleek 731 is completely dry, do not attempt to remove runs and sags The maximum allowable dry film thickness of Intersleek 731 tie coat is 6 mils (see Step ) For each section of the vessel coated, the two intermediate coats (as specified in Step and Step ) shall be applied on the same day, in accordance with Step 7.3 and the applicable ASTM F-718 documents (Ref. 2.c), and the section coated in its entirety Dry film thickness (dft) measurements shall be conducted in accordance with Ref. 2.b, but with the following modification, due to the soft nature of the dried Intersleek 731 film: a shim with known thickness shall be used to avoid denting the Intersleek 731, then the thickness of the shim subtracted from the total thickness values to obtain actual dry coating thicknesses. 11.
