1 Winner of EPA S (NPPR) 2006 MVP 2 Award (Most Valuable Pollution Prevention) a licensed applicator for: Arm rgalv thermo diffusion galvanized coatings precision heavy duty corrosion and wear protection chrome and cadmium free cost effective ASTM - A1059 A/M What is ArmorGalv Thermal Diffusion Galvanizing? ArmorGalv is the trade name for a technology developed by the Distek Group in It is a method of creating a uniform, barrier and sacrificial, zinc- iron or zinc-aluminum alloy surface using a metallurgical vapor diffusion process for heavy duty corrosion and abrasion protection on ferrous metals. ArmorGalv can be applied to many surface types: Powder Metal Steel Stainless Steel Castings& Forgings Agritek Industries Inc. 1

2 Structure of ArmorGalv coating ArmorGalv forms multiple layers of zinc-iron alloy on ferrous metals, with a super corrosion resistant inner gamma layer, compact delta layer, and outer zeta layer - like an onion. Each layer is successively harder and more corrosion resistant. Key characteristics of ArmorGalv Coating ArmorGalv zinc iron alloy coating is sacrificial, providing Galvanic protection to the steel parts, as well as a barrier coating. highly corrosion and abrasion resistant hard, non magnetic, weldable, and spark free chip proof and suitable for crimping, bending, and forming very good anti-galling properties and low co-efficient of friction excellent functional replacement for CADMIUM highly heat resistant - withstands working temperatures over F (540 0 C) provides an excellent bonding surface for paint, e-coat and over-molding with rubber or plastic ArmorGalv is totally non-toxic, and free of heavy metals.

3 ArmorGalv Coating Process Advantages: The thermo diffusion process operates at significantly lower temperatures than hot dip galvanizing ( F) versus ( F) Maximum process temperature can be precisely adjusted for each batch, based on coating characteristics of the part to be coated. Special zinc powder formulations are available which will allow parts to be ArmorGalv coated at temperatures low as 570 F. Coating thickness can be adjusted from 0.5 to 6 mils ( microns) with a +/- 10% tolerance. The process evenly coats the inside of hollow and tubular parts. Parts do not need to be fixtured, and parts with similar coating characteristics can be mixed where small batches are needed. Current process equipment can handle parts up to 7 ft. long. It is a superior replacement for hot dip galvanizing and zinc plating. No hydrogen embrittlement! ArmorGalv -- real world applications at the Dead Sea!

4 Laboratory Test Results On going salt spray test, started Dec 2, 2008, in the same A2LA Certified laboratory. These tubes are coated with 50 microns of ArmorGalv, including sealer. Results after 5,000 hours. Parts are still in the salt spray chamber with no signs of corrosion. Nut and Bolt, coated with 35 microns of ArmorGalv, after 3000 hours in A2LA Certified Laboratory salt spray test. Picture was taken on Apr parts are still in the Salt spray chamber with no signs of corrosion. Please note: white is salt encrustation no red rust! 7 ArmorGalv follows the contours of any part, creating a uniform coating thickness over the entire surface, including complex shapes and internal cavities. This ability allows for ArmorGalv to coat parts that are Traditionally impossible to coat. Agritek Industries Inc. 4

5 ArmorGalv and Castings ArmorGalv on the new Stabiloc manhole cover lock. Ductile iron castings. Armorgalv on left after 1,176 hours in salt spray, original phosphated and e- coated finish at 912 hours. Red staining on Armorgalv is from diffused iron on the surface, not a coating breach. Armorgalv outperforms! 9 ArmorGalv & Powdered Metal No Pre-Impregnation Required ArmorGalv adds new capabilities to powdered metal parts because it saturates the grain structure. It is not just a surface coating. improves wear resistance replaces resin impregnation increases density improves powder coat and paint quality can replace expensive stainless and non-ferrous powders Before ArmorGalv After ArmorGalv Agritek Industries Inc. 5

6 ArmorGalv coating is particularly useful for fasteners and other complex parts with internal threads Below is a picture of a fastener with a captive washer and a Rivnut that were coated by ArmorGalv. Notice that the Thermal Diffusion coating is extremely uniform, obviating the need to designate portions of a fastener as insignificant. The ENTIRE surface is significant and coated! Salt spray results of greater than 1,000 hours are common. 11 Top coating and overmolding ArmorGalv The smooth surface created by electro-plating requires various preparations, such a chromates and primers, to provide basic adhesion of paint, or over-molding. ArmorGalv grain structure provides a much better bonding surface than electroplated (or mechanically plated) zinc, as illustrated in the photos below. ArmorGalv surface electro plating Electro-plated Zinc surface Likewise, hot dip galvanizing creates a surface which cannot be top-coated without aging, etching, or priming. The ArmorGalv surface permits superior adhesion of any top coat. Agritek Industries Inc. 6

7 ArmorPlex : Thermal Diffusion + hi-tech polymer coatings For extremely rigorous conditions, many top coat options may be used to take advantage of the Armorgalv base and strong bonding surface. This is an ideal combination to reduce corrosion creep when the topcoat barrier is breached in continuous severe conditions.

The EPA stated that the process approaches zero discharge. The ArmorGalv Thermal Diffusion process is the winner of the 2006 Most Valuable Pollution Prevention Award (MVP2). ArmorGalv history The forerunner of ArmorGalv is called Sherardizing, Invented by British metallurgist Sherard Cowper-Coles in Due to lengthy process times and difficulties controlling coating thickness, Sherardizing operations were greatly diminished by the 1950 s. In Europe, the best known applicator of Sherardizing has been Bodycote Int l. For the past eight years Bodycote has been a licensee of DiSTeK s ArmorGalv Inventor of Sherardizing Sherard Cowper- Coles In the 1990 s Distek metallurgists discovered and patented modifications to the zinc powder formula and process controls, to reduce process time and improve consistency. DisTek continues to innovate with new formulations and process improvements today Sherardizing Plant Agritek Industries Inc. 8
