DuPont Non-Stick Dry-Film Lubricant Aerosol, 10 oz

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.

Very good product

Works well under my mowing deck

Used on the bottom of my lawn mower deck and have not had to worry about any grass or debris clumping underneath and hurting my cut. I assume I will need to re-apply every season but that's a small price to pay to not have to dig chunks of grass out from under my mower.

Have used another brand of dry lubricant on my table saw cast iron. The manufacture of that brand loves it so much they put the price out of range. Found DuPont made the same product with an affordable price tag. Also has no additives that will affect finishes.

I tried this spray on a horizontal sliding vinyl window that was squealing when it was opened or closed. It helped a little, but based on the reviews I thought it would slide like a dream. I put 4-5 coats of the spray on the track and it did slide smoother and the squealing was mostly gone. After that I bought a silicone-based spray and added it on top of the Teflon. That helped a lot. The squealing is totally gone now. I used the silicone spray on the other windows and it worked well. I also had a hand saw that I used for cutting tree branches that was quite sticky. When I bought it there was an oily lubricant on the blade and it slid smoothly. All the lubricant had worn off and once I cut about an inch into a branch, the blade would become stuck and it would be impossible to make further progress. I cleaned off the blade and added this Teflon spray, but it didn’t seem to help very much. WD40 helps to keep wood pulp from gumming up the blade but it wears off very fast. I also tried the Teflon spray on an old Miter saw blade that had started to burn wood as it cut it. Maybe the blade was already too worn for a lubricant to do much good, but the Teflon spray didn’t seem to help much. I bought a new blade and added the Teflon before using it. It works well, but then it is a brand new blade so it should work well.

Works well at fair price.

Lubricated the poly bushings on the front stabilizer bar On our Dodge Magnum Took care of the squeaks I had driven through a very, very heavy rain storm Satisfied with the product

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

Bakwas product ....Don't buy
