DuPont Teflon Non-Stick Dry-Film Lubricant Aerosol Spray, 10 Oz.

Buy only if the surfaces to be lubricated can be exposed while coating.

Bakwas product ....Don't buy

I am using this to keep wet snow from sticking to snowshoes and it is working perfect at about 1/4 of the price of aerosol ski wax.

Works well under my mowing deck

I was confused by all the different non-oil lubricating sprays available, so I purchased a variety and tested them out to compare them against one another. I found that they all have different properties and are best suited for different applications. My testing was simple. I sprayed all the lubricants for an equal amount of time over an equal area of aluminum foil. I then monitored them all over a period of a week indoors at an ambient temperature of around 20C. Then I applied 100 grams of force to each test area and subjectively assessed the amount of reduced friction. (see photos) DuPont Silicone Surface Safe Lubricant. This contains silicone, Teflon, and ceramic boron. It remained fully liquid, thin, and runny even after a week. This seems ideal in situation where you have parts that require a liquid lubricant such as bearings, etc. Best to use this in situations where you would usually use oil, but when you cannot use oil-based products. DuPont Chain-Saver Dry Lubricant. This is a molybdenum and Teflon wax-based lubricant. This remained fully liquid, very thick and waxy after a week. This is formulated for bike chains, and I can see why. Ideal for mechanical parts that must engage and disengage repetitively. Another possible use might be for zippers or similar fasteners. DuPont Multi-Use High-Performance Lubricant. This contains Teflon and silicone. This is essentially a compromise between all the other lubricant sprays. It stays liquid and wet after a week, but is not a lubricating as the others, not as non-stick as the others, and not as friction-reducing as the others. If you can only have one bottle of non-oil lubricant spray, this is a good choice, but it is not the best at any one thing. Basically, like the WD-40 of silicone sprays. Super Lube 91110 Silicone Spray. After a week, leaves a very thin, nearly dry surface, incredibly slippery with the best friction-reducing properties of all the sprays I tried. Wonderful! Also, this is H1 food grade safe (ok for use in equipment used in contact with food). If you need to reduce friction on long rail and track mechanisms with minimal tackiness that might attract dust, this seems ideal! Super Lube 11016 Dri-Film Lubricant. After a week, leaves a dry surface, rather slippery in reducing friction and rather non-stick. This is also H1 food grade safe (ok for use in equipment used in contact with food). If you must have a fully dry film lubricant, this is my favorite! DuPont Non-Stick Dry-Film Lubricant. After a week, leaves a dry opaque white film. Not really slippery or lubricating against friction, but entirely non-stick. Essentially like Teflon PTFE in a can. In situations where you want a non-stick coating like PTFE, but using Teflon tape, etc. is not an option, this seems like an excellent choice.

Great product. I used it to coat my snow blower shut. Sprayed the shut twice during the winter season. The slushy snow flew out of the housing without excessive jams. Better yet, I went through the entire season without a shear pin malfunction.

I have used "Teflon" spray (dry lube) for years. It works well, but needs to be re-applied periodically, and it leaves a white film on whatever you spray it on. This Dry lube has TWO conflicting descriptions. One place it says "100%" DuPont Teflon fluoropolymer. In another place it says "Boron Nitride". The picture of the can (which is a picture of what I received) shows, "BN non-stick ceramic" technology. So I think the Boron Nitride description is correct. You may know, cubic Boron Nitride is almost the hardest substance on earth, exceeded only by diamond. This is probably hexagonal Boron Nitride which is more like graphite, (but without the greasy gray mess). I suppose that is a good thing. You may only need to apply it once, and it will last as long as you need it. To my knowledge Boron Nitride is completely nontoxic. They even put it in certain womens makeup for some unknown reason. Fluoropolymers like "Teflon" are being criticized as chemicals that never go away. What we have made, we will have with us for a very long time. Boron Nitride is probably even more stable, and may end up as exceedingly small (nano) particles. Fortunately, people much more knowledgeable than me, regulate these kind of things. I have to say, I tried it ,and it is not messy, and it works very well. I think I will use it very judiciously in places where good old graphite (100% carbon) is inappropriate.
