In the building and construction industry, structural steel components, metal fasteners, machine components, enclosures and various auxiliary metal parts may require preparation prior to painting or the application of protective coatings. During manufacturing, storage, transportation and assembly, these surfaces may become contaminated with oil, grease, machining fluids and other contaminants. The controlled removal of these residues before painting or coating is one of the fundamental stages of the surface preparation process.
The operating principle of degreasing is based on dissolving, emulsifying or otherwise enabling the removal of oily contamination from the surface using a suitable chemical system. Alkaline degreasing systems may be used particularly on large metal surfaces or in process-based applications. For localized maintenance applications, suitable solvents or industrial degreasers may be selected according to the nature of the contamination.
Following degreasing, the surface must be brought to a condition suitable for the subsequent process. Controlling undesirable ionic residues that may originate from the cleaning chemical or the water used in the process and, where necessary, incorporating a neutralization stage can form an integral part of pre-paint surface preparation.
Surface preparation should not be regarded as a chemical cleaning process alone. Where rust, mill scale, loose existing paint or physical surface defects are present, appropriate mechanical preparation methods should also be applied. Chemical degreasing represents the stage of the overall process specifically intended to remove oil and process-related contamination. The sequence of operations should be determined according to the type of metal and the technical requirements of the paint or coating system to be applied.
