K2 graphite Lubricant Spray, Graphite, Graphite Spray Graphite Lubricant, 400ml

Product Information

The options that seem to be the cleanest are the more earth-friendly lubricants, which also utilize a more precise application process.

Tungsten disulfide. Similar usage as molybdenum disulfide, but due to the high cost only found in some dry lubricated bearings. Graphite is structurally composed of planes of polycyclic carbon atoms that are hexagonal in orientation. The distance of carbon atoms between planes is longer and, therefore, the bonding is weaker. We love that it goes on clear, unlike many dry lubricants, which can leave a residue. This also means it can be difficult to see where it has already been applied, but we think the tradeoff is fair.We independently review everything we recommend. When you buy through our links, we may earn a commission. There are two main types of dry-film lubricants, which are known as crystalline lattice (lamella) type structures such as Molybdenum Disulphide, Tungsten Disulphide and Graphite( DRY MOLY, DRY GRAPHITE SPRAY, etc) and Fluorocarbons such as PTFE ( DRY PTFE). Ceramics. Another application is for cases where chemically active lubricant additives have not been found for a particular surface, such as polymers and ceramics.

Graphite is best suited for lubrication in air. Water vapor is a necessary component for graphite lubrication. The adsorption of water reduces the bonding energy between the hexagonal planes of the graphite to a lower level than the adhesion energy between a substrate and the graphite. Because water vapor is a requirement for lubrication, graphite is not effective in vacuum. [4] Because it is electrically conductive, graphite can promote galvanic corrosion. In an oxidative atmosphere, graphite is effective at high temperatures up to 450°C continuously and can withstand much higher temperature peaks. However, it does fall short in one regard. It doesn't include a plastic straw applicator, so accurately shooting it down a keyhole is slightly obnoxious. But it does clean up nicely. Polytetrafluorethylene (PTFE) is widely used as an additive in lubricating oils and greases. Due to the low surface energy of PTFE, stable unflocculated dispersions of PTFE in oil or water can be produced. Contrary to the other solid lubricants discussed, PTFE does not have a layered structure. The macro molecules of PTFE slip easily along each other, similar to lamellar structures. PTFE shows one of the smallest coefficients of static and dynamic friction, down to 0.04. Operating temperatures are limited to about 260°C.Synthetic graphite is a high temperature sintered product and is characterized by its high purity of carbon (99.5−99.9%). Primary grade synthetic graphite can approach the good lubricity of quality natural graphite. In crystalline form structures such as DRY MOLY and DRY GRAPHITE, the shear forces between opposing layers are weak resulting in lubricity between sliding surfaces. We can’t help but love WD-40 Specialist more because it works perfectly, and the application bottle is better. 3. Quest Specialty Micro-Dry PTFE Dry Lubricant & Release Agent – Considered for Best PTFE Infomak is dedicated to the technology development of special oil additives, combined the t echnology of nanomaterials developed dry lubricant and oil additives two series. Our products can significantly improve the performance of lubricating oil, improve energy efficiency, effectively protect the lubrication device and extend the oil change cycle, which can satisfy the lubrication oil constantly upgrading for high-end engine oil additives. However, a layered crystal structure alone is not necessarily sufficient for lubrication. In fact, there are some solids with non-lamellar structures that function well as dry lubricants in some applications. These include certain soft metals ( indium, lead, silver, tin), polytetrafluroethylene, some solid oxides, rare-earth fluorides, and even diamond. [2]
