Finish Line Teflon Synthetic Grease

Product Information

I’ve also explained what the minimum requirements are, how to read and compare characteristics of a particular product. Graphite is added to a grease as a solid lubricant, to improve extremely high load bearing characteristics. It is usuallycombined with calcium, or aluminium greases. Bearing extremely high loads is completely needless attribute for a bicycle bearing grease. You will needlessly pay more, with no measurable practical (or even theoretical) benefits. Soap greases. Soaps are usually made by saponification of fatty acids with hydroxides of various metals – aluminium, calcium,sodium, barium. Dirt intrusion (the main reason why bottom headset bearings get busted a lot sooner than the top ones).

With a better quality grease, this can be extended somewhat, but most problems in bike bearings come from dirt contamination, even more than from water washout. To be more specific – water washout creates a problem if bearings are not serviced at least annually, with riding in wet conditions AND not using a higher quality grease.DIN and ISO standards are just that, standards that are pass/fail. None of commonly available greases will fail any of the DIN and ISO standards you’re harping upon so how are you differentiating anything? Which greases are you trying to highlight fail these standards? This emphasis on DIN and ISO standards not realizing that none of these greases will fail those tests again indicates the level of understanding in the area. This is exactly the pseudo intelligence I am speaking to, you hype up and reiterate the importance of DIN/ISO/NLGI standards not realizing ANY of the greases available for automotive/bicycles won’t fail those standards based upon base oil composition. Even your personal experience, by your discussion with Reason, shows you have no experience with other types of grease on a bicycle and zero experience with any in a lab environment so that’s not a relevant point either. Bicycle bearings don’t require any special grease IMO, as I’ve (tried to) explained in this post. Most any will do, while you can hardly go (measurably) better than a good quality lithium complex soap based grease with mineral base oil. For pressing in the bearings (not for lubrication of moving parts), I prefer (and recommend) using some kind of anti-seize, not grease. Because it provides long(er) term protection from seizing (corrosion), helping both with mounting and dismounting. Grease can be relied upon for only up to one year, if not even shorter period, for anti-seize protection. Products sold as “copper grease” are quite good for that task.

Are you serious? THE ENTIRE ARTICLE the first thing you list in each type is water resistance. Literally. Yes there’s variation between each exact formula but no, lithium soap is lithium soap. It washes out. For a wide range of working temperatures (for -25 °Cto hottest Africa heat), with very good water resistance attributes, but not too expensive – lithium complex greasewith ISO water resistance level I. With, or without EP additives (doesn’t really matter). Still, this grease costs about double the price of ordinary lithium, or calcium based greases. In addition to that, I haven’t noticed any problems with using NLGI 2 grease. Lubrication, water washout resistance, even drag – none. On the other hand: price, availability and convenience (if servicing loose ball bearings) – all go in favor of NLGI 2, at least in my region. The original Park grease seemed fair, but definitely would allow and absorb more water into emulsion which could lead to bearing corrosion. Because it isn’t designed for prolonged water exposure, because it’s not designed for what you’re trying to make it claim, it’s NOT on the data sheets. There is no “ISO E” universal standard that all data sheets have so you’re looking for a statement that very few, if any, manufacturers claim.

Halfords Teflon Grease, 125ml

Grease used for (and marketed as) boat trailer wheel bearing lubrication. Bearings that need to be submerged into sea water when boats are put into the sea. Very good corrosion and water washout resistance. Use temperature range is similar to ordinary calcium greases (if it is complex, then like complex calcium greases). Relatively low price (similar to calcium, or complex calcium greases). Relja – This is the same consistent misunderstanding you gave to ‘Reason’ earlier. You simply don’t understand the topic as well as you believe. The brand name Zepel was used for promoting its stain-resistance and water-resistance when applied to fabrics. [12]

Synthetic greases.With synthetic base oils. Usually have properties superior toother comparable greases. With a (significantly) higher price. Easily compared yes, but you don’t do it once in the entire article. Not once do you actually compare the greases on any scientific metric.” Basically we can conclude that you have literally zero data comparing the greases to substantiate your opinion. This is what you’ve shown thus far. First. Some days ago I bщгпре a calcium grease Motul Nautic Grease. It has temperature range from -30 C to +120 C. Also I have bicycle lithium TF2 Grease with temp. range from -20 C to +120 C. In this case calcium grease has better temperature range than lithium grease. But in article “These greases have a relatively narrow working temperature range. I.e. if bicycle is ridden below -20 °C, or it stays in hot summer sun before riding (over +35 °C), then they are not the best choice”. I ride in any temperature range (-30 – +35) and in any weather conditions. Also salt protection is very matter for me becouse salt applied to roads to protect against ice. So is my choose enough good and calcium grease have better temp. range than lithium grease? My second choice would be a more frequent application of some PTFE spray lubricant (low-viscosity, “thin” oil-based lubricant) – i.e. just not WD40 (to emphasize that just to be on the safe side).Polytetrafluoroethylene (PTFE) was accidentally discovered in 1938 by Roy J. Plunkett while he was working in New Jersey for DuPont. As Plunkett attempted to make a new chlorofluorocarbon refrigerant, the tetrafluoroethylene gas in its pressure bottle stopped flowing before the bottle's weight had dropped to the point signaling "empty". Since Plunkett was measuring the amount of gas used by weighing the bottle, he became curious as to the source of the weight, and finally resorted to sawing the bottle apart. He found the bottle's interior coated with a waxy white material that was oddly slippery. Analysis showed that it was polymerized perfluoroethylene, with the iron from the inside of the container having acted as a catalyst at high pressure. [4] Kinetic Chemicals patented the new fluorinated plastic (analogous to the already known polyethylene) in 1941, [5] and registered the Teflon trademark in 1945. [6] [7]
