Solid lubricants are usually used for lubrication applications running under extreme conditions (e.g. application in the boundary friction area). Setral® has a portfolio of products (MIPO® series) to offer that often can be used as an alternative to molybdenum disulphide (MoS2). The usage can be directly as powder, in suspensions, in pastes, in lubricating greases, in metallic films, in bonded lubricants etc.. Typical applications are e.g. anti-friction linings, rubber, plastics etc..
Pastes are used in very slowly running bearings (rolling and plain bearings), under simple sliding procedures, as assembly pastes, separating agents or as high temperature pastes at temperatures above +300°C (evaporation of the base oil). The use of solid lubricants make pastes suitable for extreme heavy load applications. In the broad range of pastes of Setral® the MIPO® technology is used for the improvement of the separation and lubricating properties.
Greases are the "all-rounder" among the lubricants and find use in practically every industry. They cover broad ranges of temperature, speed and load. Application areas can be in dry, dusty as well as wet, corrosive environments. Setral® lubricating greases are often based on "MolyGold®" , a particularly developed technology for the reduction of wear and friction.
Bonded lubricants are pure specialists and are used above all where their advantages like clean working, economical lubricant consumption, stability under vacuum, resistance to radioactive radiation and very wide temperature range (- 200 to +650°C - > space) are particularly demanded. Bonded lubricants always consist of a solvent, a binder, and a solid lubricant. Setral® uses among others its MIPO®-technology as solid lubricants.
For easy application the most important Setral®-products are also offered as aerosols. Especially in work shops and maintenance they are favored because of their easy handling. It speaks for itself that one can also find the products based on MIPO® and MolyGold® technology in this range. On top of this there are also products having NSF H1-listing which are suitable for food processing machinery or applications where physiologically safe products are required.
The performance requirements for modern lubricating oils, especially in high temperature application are continuously increasing. Setral® high temperature oils are developed for these application in particular and are very often based on the MolyGold® technology. As an example oils for the chain lubrication suitable to work at temperatures up to +300°C (containing solids up to +600°C), should be mentioned here. Besides outstanding ageing resistance, lowest possible evaporation losses and consequently reduced consumption are expected.
In many applications common hydraulic-, gear and compressor oils cannot withstand the increased requirements. Nowadays modern compressor oils offer a lifetime of 10.000h and more. This is only feasible by means of using suitable base oils and additives. In gear boxes high performance gear oils based on MolyGold® provide reduced friction and thus reasonable energy savings and longer life because of lowered steady-state temperatures.
No other range of lubricants came into focus regarding toxicity and environmental impact like metal working oils did. Reasons for that among others were the direct exposure of the user (skin contact, aspiration) and the problematic waste water treatment in case of the water miscible oils. Setral® metal working fluids meet these requirements but they also guarantee the required cutting, grinding and lapping properties by using state-of-the-art formulation.
The best possible performance of high performance lubricants can be achieved by means of professional cleaning of the machine parts prior to initial filling. By doing so the best contact of the lubricant to the surface can be assured. Besides outstanding cleaning effect, environmental friendliness and protection of the user has to be taken into account. Depending on the application water soluble as well as solvent based cleaners are offered.
Additives are used to support or improve existing properties of the lubricant/base oils. This includes e.g. oxidation stability, load carrying capacity (EP-properties) or lubricity. They can also be used to generate additional properties such as corrosion protection, wetting properties, flow at low temperatures. Making special lubricants requires the use of synergistic combinations of different additives as can be found in the MolyGold® technology.
