Varnishes are used every day, both to coat the surface of wood and to be applied to teeth as fluoride. It is a thin, sticky, black or brown deposit that can be found inside lubrication systems (Guerzoni, F. 2009). The varnish is thin and insoluble and can also be found on bearings and servovalves (Badal, L et al. 2005). Varnish is a high molecular weight substance insoluble in oil (Badal, L et al. 2005). Paint buildup in machinery can eventually lead to maintenance problems (Guerzoni, F. 2009). Varnish is difficult to remove and forms when a lubricant decomposes due to a number of factors such as the age of the oil, the condition of the equipment, i.e. maintenance practices (Guerzoni, F. 2009). Varnish can also be formed “from turbine oils sourced from insoluble materials under severe or unusual operating conditions” (Badal, L et al. 2005). There are some factors that can accelerate the accumulation of paint such as: “hot spots, cold spots, air entrainment, metal catalysts, water and contaminating oil” (Guerzoni, F. 2009). Paint can affect machinery in various ways, for example: “reduced oil life, loss of heat transfer in heat exchangers, decreased filter life, increased damage to bearings, gears, seals and valves, and sticking of moving parts” (Guerzoni, F.2009). Paint can be associated with operational problems on the movement or operation of a machine, contributions to wear and corrosion, increased wear of components due to dirt attracted to the paint, blockage of small orifices, damage to mechanical seals and being an insulator thermal which causes more heat, friction, and energy in machinery (Badal, L et al. 2005). Paints can also cause businesses unexpected repair costs and extended downtime, causing a...... middle of paper ...... cellulose, synthetic, polyurethane, water-based, and wood acid-cured paints used.
