In Malaysia on wet surfaces after water-jetting Large SBM in tropical marine conditions requiring complete refurbishment used Alocit primer and second coat with PU topcoat above waterline Water jetting with garnet was used to prepare surfaces – with painters following immediately after – Shell engineers estimated 30% cost saving using Alocit A full testing regime was carried out. Pull off showed 1200 p. s. i. adhesion after w/jetting

In Alabama and New York Harbour on sheet piles Chosen by contractors because Alocit 28. 15 adheres so strongly and is surface tolerant, with no need to worry about oil or water contamination Alocit coatings have been in use by the Port Authority of New York and New Jersey for many years – on tunnels, airports and sheet piles in the harbour The video shows a short extract from underwater footage taken by a contractor And in the United States …

US Army Corps of Engineers Alocit is one of only three coatings listed by USACE as meeting its criteria for application on wet areas – and it the only one of the three that can be applied underwater! Dupont Used for encapsulating PCBs and other harmful contaminants in concrete. Tested by United Power Services using EPA protocols, following coating with Alocit, PCB levels at the surface were below detectable limits Shell in Texas on sweating pipes Competitive testing by Shell to find the most suitable coating for application on to cold pipes (34°F), streaming with water in the warm Gulf climate, found Alocit 28. 15 to be the most suitable coating for such situations. Following testing, Alocit was given global approval by Shell

National Oceanic and Atmospheric Administration On the Oregon ll in Louisiana, on ballast tank, bilge areas and the machinery room deck. Preparation was by machine tools and blasting followed by coating with 28. 15 gray, white and red Alocit coatings have zero VOCs and paint inspectors commented on the odor-free atmosphere during coating works on the Oregon

USS Detroit Full scale test application in the Port Shaft Alley Bilge completed in 2000 as part of the NAVSEA approval process. Follow up inspection by CES for NAVSEA in 2001 found the Alocit 28. 15 coating to be ‘performing flawlessly in severe service’ The finished Port Shaft Alley bilge area

Bilge Preservation – ALOCIT 28. 15 Surface preparation: SSPC SP-11 Power Tool Cleaning to bare metal. Coating Application: (All material is ALOCIT 28. 15 in 3 colors) Bilge area: Prime coat Stripe coat Finish coat White Gray Terracotta 5 -7 mils WFT/DFT Prime coat Stripe coat Finish coat Gray White 5 -7 mils WFT/DFT Above Bilge: The subcontractor, UCC, was tasked to provide the in-process OA. Since the CES representative was on hand throughout the process, the OA became a joint effort that produced very satisfying results with no surprises. SUPSHIP attended all checkpoints and validated the results. The test application was successfully completed with the Shaft Alley turned over to Ship's Force in April 2000. The shaft alley was surveyed May 2001 while USS Detroit was at home port at NWS Earle, NJ. The Alocit Aquacoating system is in immaculate condition with no deterioration of any kind noted There is standing salt water in the sump area and some mold and mildew growing (the ventilation in this space is poor). There was no corrosion of any type noted. Much of the steel in this space (bilge) is heavily pitted and without this re-preservation would be holed through (some steel replacement was accomplished in conjunction with the re-preservation in 2000).

What make Alocit so great? You can apply it on the wettest of surfaces As you can see from these flange bolts, from an application to pipework running at 38°F on an industrial cooling system, underground at KLCC in Malaysia It gives fantastic adhesion Tests on the Detroit showed adhesion beyond the ability of the testing equipment they were using (above 1000 p. s. i. ) Use it straight after water-jetting Independent comparative testing, using coatings on surfaces exclusively prepared using ultra-high pressure water-jetting, showed Alocit to be have nearly twice the adhesion of its nearest rival. NAVSEA PPIs allow Alocit 28. 15 to be used without drying surfaces

What make Alocit so great? It can be used on oily surfaces Oil-soaked bund areas, which might otherwise have to be rebuilt, can be coated with Alocit, preventing escape into the environment. On the right is the floor of a railroad maintenance tunnel in Switzerland, covered in oil before being coated with Alocit. The video shows Alocit being applied to oily concrete – underwater! It is very hard wearing and long-lasting The Dutch Navy use Alocit because it last so well in its tanks – even where constant high pressure flows would abrade lesser coatings. In Germany, on water treatment plants, case histories show more than 30 years constant use in aggressive waste water without deterioration

Testing For use with Cathodic Protection By DNV on test plates in Norway and Zinga in Korea on round steel piles. Alocit has been used in conjunction with CP systems for many years with no reported failures Long-term immersion following underwater coating By German State testing agency on samples in the North Sea, coatings performed underwater on steel panels at two year intervals. Inspection after 6 years immersion showed no deterioration, despite the need to chip off extensive marine growth Testing for use in tropical marine conditions On test plates coated underwater for Brazilian National Oil Company (Petro. Bras) : 480 hour salt fog (ASTM B 117 -73): No corrosion - no penetration of corrosion from scribe Exposure to environment with an air humidity 85% (underwater and in the range air/water) for 1000 hours (NBR 7351): no corrosion 40°C salt water immersion (ASTM D 1308): 360 hrs - no corrosion, 1000 hrs - no corrosion

Testing LPM Swiss Testing Many tests have been performed by LPM for Alocit over the years, those shown are a summary of standard tests

Testing Alocit primer based system on fresh pre-cast concrete Undertaken by the contractor for the Singapore MRT in order to show that, using an Alocit primer, steam-cured concrete casting sections for the MRT tunnel could be coated within minutes, without waiting for the concrete to dry. It would normally be necessary to wait for the moisture content of the concrete to fall below recommended levels in order to coat. Removing the waiting and consequent storage and extra handling brought major cost savings.

Practical matters The Alocit System Alocit 28. 15 is a two-component epoxy coating. 100% solids and VOC free, it can be applied using brush, roller or spray (airless or using dual-component pump) It is supplied as standard in 1. 2 kg and 3 kg packs, supplied as kits with hardener and base pre-measured for mixing Standard White, Black and Gray are available from stock plus Fed Std 595 Green, Gray, White, Red, Light Gray & Black RAL and other international standards to order A high standard of quality control, monitoring color consistency and application quality, is at the heart of Alocit’s ability to outperform its rivals. Uniquely engineered to adhere on the most challenging substrates, while at the same time maintaining a level of usability without sacrificing environmental standards QUALITYCONSISTENCY COLOR APPLICATION CONTROL QUALITY

Application General guidelines Above water, Alocit 28. 15 can be applied using brush, roller or spray equipment. Spraying can be either by airless sprayer (Graco King) or dual-component pump (Hydracat) Below water a brush must be used but powered brush systems are available for covering large areas, these can be either single or dual-component units Wet substrates Particular attention must be given to providing a suitable profile during preparation for wet surface application with a minimum 2 mil profile. Brush strokes, preferably using a round short-bristled brush, should be firm, using a circular motion. The material will cure underwater at the same speed as it does above – the main criterion being temperature. The video show NZ Navy divers applying Alocit to a damaged prop shaft

Application Contaminated substrates – oil & salt As with all coating systems, Alocit requires that the substrate be sound and free from poorly adherent coatings or loose material. The same general principles apply to coating on oily or salty substrates. Residual oil is acceptable, but if you try to coat over pools of oil you will not succeed – a wash to remove these is just common sense. The same applies to salt contamination, surfaces that have been in contact with salt water, even for long periods will not be too salty to coat with Alocit, providing they meet other normal preparation standards – profile etc. Salt crystals and other loose solids should be removed in the normal way – in most cases normal preparation will reduce salt to perfectly acceptable levels without any special consideration being given for their reduction before coating with Alocit. Conclusion No coating can be all things to all men, but, if you want a hard-wearing coating with outstanding adhesion, low odor and exceptional surface tolerance – then Alocit 28. 15 fits the bill perfectly. 100% solids, with zero VOCs, it meets the highest environmental standards without compromising on performance or usability.
