Guarding Against Corrosion
Products for Museums
© Shield Technology 2008
Many of the products designed by Shield Technology have found uses in museums and private collections - particularly those involved in the preservation of technological artifacts. Perhaps the most widely used is ToolGuard VCI. Unlike desiccants that dry the atmosphere, VCI technology inhibits corrosion at source by interfering with the electrochemical process at the surface of the metal. The Rahmi M. Koc Museum of Technology in Istanbul uses a number of Shield Technology products to protect its exhibits, in particular ToolGuard VCI which are used in many display cabinets.
EngineGurad Aero has been extensively tested and used by the Shuttleworth collection at Old Warden, Bedfordshire to protect an inhibited 'spare' Rolls Royce Merlin aero engine.
Other major UK based Museums are currently evaluating a number of products.
MetalGuard Ultra is a high specification thin film coating which leaves a 2 micron clear film which will not yellow with age. It contains both ferrous metal and yellow metal corrosion inhibitors. Supplied as a liquid in either 250ml or 1 litre cans it can be applied by brush, spray or dipping. Unlike the majority of other thin film coatings available on the market, it complies with defence standard 68-10/2 (PX24) and NATO CODE C-634 which is indicative of the quality of the product. Under typical workshop conditions it can be expected to provide protection for up to two years. MetalGuard Ultra does not contain silicone.
Arc Euro Trade use MetalGuard Ultra to protect the surfaces of their specially prepared machine tools.

GreaseXtra is a grease made from a high quality gelled mineral oil with the addition of corrosion inhibitors. It has a melting point of approx. 200 Deg C. and is particularly difficult to emulsify. Typical applications therefore include the lubrication and protection of live steam models. It has also found favour with the boating fraternity as a lubricant and inhibitor for the wheel bearings of launching trolleys. GreaseXtra does not contain silicone.

ProtecTool wax polish, is the latest corrosion inhibitor to be added to the Shield Technology range, designed specifically for the woodworker but which is rapidly finding new uses by metalworkers and model engineers. ProtecTool wax is a unique blend of soft microcrystalline waxes and corrosion inhibitors that hardens on exposure to air. It is applied with a soft cloth, allowed to dry for a few minutes and then buffed. In addition to protecting tools such as hand planes and saws, and machine tables it reduces friction dramatically.

EngineGuard Aero has been specifically formulated to provide outstanding protection to Aero engines that are used infrequently or that are inhibited and in long term storage.
EngineGuard Aero contains both contact and vapour phase corrosion inhibitors. The VCI component provides protection even if the liquid is not in contact with the internal surfaces of the engine. The base product of EngineGuard Aero is a highly refined mineral oil, which means it is compatible with the majority of aero engine lubricants.
The effectiveness of the VCI compound has been comprehensively tested. It is both fast acting and long lasting. It does not have to be drained-down prior to running the engine.
Dosage. For the majority of light aircraft engines, add approx. 100 to 125ml to the sump. For long-term storage, where possible, block off breather pipes and exhaust/inlet ports and insert a rag dampened with EngineGuard Aero into each exhaust and inlet port. Close with purpose made blanking plugs or poly bags. It is not essential for the system to be 100% sealed for EngineGuard Aero to give protection.

ToolGuard VCI is a vapour phase inhibitor for protecting tools and tooling stored in drawers and toolboxes and manufacturers packaging. The VCI chemical is absorbed into a felt pad inside a 35mmm dia. lidded plastic pot. On removal of the lid, the VCI chemical permeates the enclosed volume forming a monomolecular protective layer on every surface; be it steel, iron, wood, plastic etc. Because it is a vapour, it will find its way into every nook and cranny. ToolGuard VCI works at up to 100% RH and is effective for 12 months in a volume of 2 cubic feet. They are ideal for protecting precision measuring equipment, collets, hand tools and machine accessories. Because it does not lower the level of humidity, like silica gel, it will not distort any delicate pieces of a model made from wood - which ‘moves’ with changes in humidity. ToolGuard VCI has found many applications other than those just listed. Museums use them to protect artefacts in display cabinets, the shooting fraternity have used them with great success in gun cabinets, and woodworkers use them for protecting valuable hand tools. ToolGuard VCI is available singly, in packs of three or boxes of ten.
