It can be applied to moist steel surfaces and in high humidity conditions. In high temperatures, it is advisable to wet the surface and then apply Emer-Tan whilst still damp. Apply a liberal coat of Emer-Tan to the rusted areas and allow 4 - 6 hours for the conversion of the rust to an Iron Tannate Phosphate to occur. Where possible wet the treated surfaces again with water to aid the Emer-Tan penetration and conversion rate, leave until surface turns blue/black for the conversion to be fully complete in approximately 24 hours. Prior to coating and in any event, within 48 hours of conversion, before any surface contamination occurs, wipe off any loose powdery deposits with clean dry cloths, then prime immediately with Emer-Gard Primer Type 2. Note: Emer-Tan contains acid. Store in plastic, rubber lined, glass or stainless steel containers. Rubber gloves are recommended for extended use. Cleaning Emer-Tan should be removed from tools and equipment with water immediately after use. Supply Product Code: 561610 (5 Litre) Emer-Tan: 5 litre Coverage Emer-Tan: 15 - 20 m2 per litre The coverage figures are theoretical – due to wastage factors and the variety and nature of possible substrates, practical coverage figures may be reduced. Storage Shelf life Emer-Tan has a shelf life of 12 months if kept in a dry store between 5°C and 30°C in the original, unopened containers. 205 Emer-Tan Tannin phosphate, rust-converter for corroding metal, pre-painting treatment Uses The versatility of Emer-Tan application makes it suitable for small or large surfaces, inaccessible areas or wherever rust is present. As a surface pre-treatment for rusted structural steel, machinery, gates, railings, marine fittings, motor vehicle floors and all rusted surfaces where the complete removal of rust is not feasible or economical. Steel surfaces treated with Emer-Tan can also be welded, coated, galvanised or chromed. Description Emer-Tan is a synergistic blend of tannin, phosphoric acid and selected surface active agents which produces a safe and extremely effective rust passivation coating, to halt corrosion. Emer-Tan Rust Converter has a three fold action: 1. Displaces all moisture from the rusted surface, 2. Penetrates into all crevices, and 3. Converts the rusty layers into a stable Iron Tannate Phosphate complex. Technical Support Parchem offers a comprehensive range of high performance, high quality products suitable for use in the protection and repair of steelwork and concrete. In addition, the company offers a technical support package to specifiers, end users and contractors, as well as on-site assistance. Properties Colour: Brown Finish: Flat blue/black Drying times: (25°C, 50% RH) Re-coat: 4 - 6 hours Application Instructions Surface preparation All surfaces to be cleaned free of dirt, grease, oil or other contamination prior to the application of Emer-Tan. If necessary, remove all surface grease or oil with a detergent, and then rinse surface with cold fresh water before applying Emer-Tan. Steel surfaces to be hand or power tool cleaned to remove all loose scale, flaky rust or other contamination. On heavily corroded areas needle gun or similar method may be necessary to remove heavy rust build prior to hand cleaning. Prepainted surfaces to be scraped and sanded to remove any loosely adhering coatings and feathered back to a firmly adhering edge. June 2014 June 2014 Page 1
