1 Solutions for Coal processing Protecting the value of your assets

2 Coatings for all your coal processing demands... We protect the high value assets required for processing coal against the harsh corrosive environments faced in this industry. Our new construction coatings specification will be tailored to your specific coal processing facility needs. Getting the coating schemes right early in the design stage can optimize the design life and significantly increase the time to first maintenance. Dry ore handling areas Wet areas - coal preparation plant Desliming screen Marine environment - transportation Dragline Primary drain and rinse screen Screening Primary dense medium cyclones Desliming cyclones Secondary drain and rinse screen Coking coal Train load out Coarse ore stock pile Secondary dense medium cyclones Thermal coal ROM Thickening cyclone Fine coal Classifying sleve bend Spirals Stacker/reclaimer Dry to wet areas - coal handling plant Flotation cells Belt filter Wet internals and externals Thickener Conveyors and transfer houses Site tankage Export terminal

3 Guideline steel and concrete coating systems COATING SYSTEM SUBSTRATE ENVIRONMENT PRODUCTS SYSTEM PROPERTIES FEATURES AND BENEFITS System Steel Dry and non-aggressive environment Interzinc 22 High zinc content inorganic zinc silicate offers corrosion protection in a single coat Excellent galvanic corrosion protection that protects steel in dry abrasive environments. Single coat reduces lead time without compromising long term performance System Steel Dry (occasional exposure to moisture) Interzinc 52 Interseal 670HS Zinc rich epoxy primer combined with immersion grade high build epoxy with ability to cure at low temperatures Excellent galvanic corrosion protection coupled with good barrier protection for long term anticorrosion performance. Improved application flexibility System Steel Dry externals Intergard 251 Interthane 990 Fast drying anticorrosive zinc phosphate primer and highly durable polyurethane topcoat Provides cost effective corrosion protection coupled with long lasting color and gloss retention means your asset looks good for longer System Steel Dry externals - premium offer Interzinc 52 Intergard 475HS Interfine 878 Zinc rich epoxy primer, high build epoxy intermediate combined with market leading acrylic polysiloxane topcoat Provides superior galvanic corrosion protection with unrivalled color and gloss retention means your asset looks good for a greatly extended time to first maintenance even above polyurethane finishes System Steel Wet areas including areas where chemical resistance is required Intercure 200 Rapid cure zinc phosphate primer and a high solids, low Volatile Organic Compound (VOC), chemical resistant, modified epoxy with single coat high build capabilities Reduces costs by minimizing maintenance even in areas subject to impact, abrasion and sulphuric acid attack experienced in coal processing System Steel Internal surfaces of thickener tanks Intercure 269 Fast cure cost effective blast holding primer and a high solids, low VOC, chemical resistant, modified epoxy with single coat high build capabilities Reduces costs by minimizing maintenance even in areas subject to impact and abrasion attack experienced in coal processing System Steel Internal surfaces - potable water Interline % solids, zero VOC, solvent free epoxy lining for the protection of steel in fully immersed environments Suitable for application in a single coat using standard equipment for fast construction and return to service. Provides corrosion protection for steel against a range of cargoes including potable water, crude oil and white oil Steel Internal surfaces - lube oil, diesel fuel Interline 984 Solvent free, epoxy phenolic tank lining with fast curing and high build capabilities Specifically designed to provide corrosion protection to the internals of steel storage tanks whilst providing chemical resistance across a range of chemicals. High build and fast curing capabilities increase the speed of applications contributing to fast track construction and fast return to service Steel Internal surfaces - process water Intercure 200 Rapid cure zinc phosphate primer and a high solids, low VOC, chemical resistant, modified epoxy with single coat high build capabilities Reduces costs by minimizing maintenance even in areas subject to impact and abrasion attack experienced in coal processing System Steel High abrasive internals Intershield 803 Intershield 803 Excellent impact and abrasion resistance meaning longer term corrosion protection than traditional epoxy systems that contributes to greater operational productivity Specifically designed to provide long term protection against impact and abrasive demands placed on internals during ore transportation. Increasing the time the assets stay in service System Steel Immersed and splash zone marine exposure Interzone 485 Immersion grade, low VOC, modified epoxy designed for ultra high build applications using standard equipment Interzone 485 can be applied in one single coat reducing application time while provide excellent barrier protection for steel against impact, abrasion and splash zone experience in marine environments The above systems are intended as general guidance and are NOT specifications. Please contact your local representative who will be able to help write a specification tailored to your needs. No substitute for International experience Reducing maintenance will contribute to lowering the cost of production per ton of coal and boost output, helping to minimize maintenance shutdowns. That s where we come in. AkzoNobel s sustainable coatings solutions can help to increase your productivity by keeping your assets in service for longer. The process illustrated to the left is designed as a guide to highlight the wide range of systems that we have available, which offer the best value added solutions to the problems encountered on a coal processing site. Although not clearly evident from the diagram, we have been protecting structural steel assets in mining for over 40 years. The nature of coal processing exposes steel and concrete to high abrasion, impact damage and the corrosive effects of acidic process water. These high value assets require fit for purpose coatings that provide long term, cost effective protection. The International protective coatings range from AkzoNobel is best suited to protect process equipment, structural steel and concrete at both new construction and maintenance and repair based on the individual micro environment.
