| Rust Removers-Deox-Gel |
|
Bilt-Hamber Laboratories produce innovative proprietary rust removers that are non-toxic, biodegradable and extremely effective. These rust removers overcome the considerable risk to the user of toxic mineral acids. Whilst mineral acids such as hydrochloric acid are effective at corrosion removal they also liberate corrosive gases which accelerate damage to any unprotected material around the area of treatment. Deox-Gel is a viscous, highly thixotropic, rust remover, designed for corrosion removal on surfaces. Blast cleaning is an effective method of corrosion removal but it's not without its drawbacks. Grit embedment can cause localised corrosion cells with associated coating failure. Copper and coal slags are widely used as abrasive media but can liberate dangerous levels of heavy metals into the atmosphere around the blast cleaning operation. Deox-Gel
Deox-Gel is a viscous, highly thixotropic, rust remover, designed for corrosion removal on surfaces or objects too large to submerge in a bath of Deox-C. Along with the viscosity builders and preservatives, the active agents in Deox-Gel are harmless, non-toxic and biodegradable. ComparisonAbrasive cleaning methods such as grinding, sanding or blast-cleaning will remove sound steel surrounding corroded areas. The risk of grit inclusion resultant from blast-cleaning, has been proven to cause early coating failure, corrosion and mechanical wear. Slag-based blast cleaning media all contain heavy metals which when used in open-nozzle blast-cleaning equipment give off dust that may contain harmful levels of these elements. Use of Deox-Gel will eliminate the risk of distortion to thin steel sections, which can result from the blast-cleaning process. How to use Deox-GelThis medium to heavily rusted steel plate has been degreased with a water-based degreasing agent.Deox-Gel is a thick paste designed to create a deep coating that de-rusts items too big to soak in a deox-C bath. (left pic of the upper pics) Here a brush is used to smooth the Deox-Gel across the rusted surface, the gel must remain in a thick even layer; brushing out to a thin coat must be avoided. Spatulas or trowels may also be used to spread Deox-Gel. For very large areas pressure pot spray systems can be used. (Right pic of the upper pics) The applied Deox-Gel is covered with plastic wrap to assist in the retention of moisture. After 12 hours undisturbed the plastic film can be removed – the gel has darkened through corrosion absorption. A steel rule is used to push back the gel layer, demonstrating the effectiveness of Deox-Gel. After a scrub with a stiff plastic-bristled brush and plenty of water the treated area is clean and ready for protection. (Left pic of the lower pics) |
