No, not all lubricants are the same. This is definatly true for silicone sprays.
No, not all of them are "safe" for airsoft use. NO WD-40, liquid wrench, PB Blaster, etc... or real steel gun products! (thanks BroodRed, I forgot this one) What do you need to know, or do about this. - Well, read below. Silicone spray lube: Generally any should work..... Provided - it does not contain any: petroleum distilates, petroleum by-products, Hydro-Carbons, or any harsh petroleum based products, Such as: Hexane, Heptane, Toluene, Xylene, Ethelene, Xylol, Toluol, Naptha, benzene or any other flamable substance! (aside from the propellents listed below). If it is using ISO-Butane, or propane "as a propellent", that is fine. Silicone Grease: (paste, non aerosol, whatever.. - This also goes double for ANY other type of grease.) Again, you want a grease without the same chemicals listed. Does not contain any: petroleum distilates, petroleum by-products, Hydro-Carbons, or any harsh petroleum based products, Such as: Hexane, Heptane, Toluene, Xylene, Ethelene, Xylol, Toluol, Naptha, benzene or any other flamable substance! Recomended Lubes and Greases: Permatex dielectric grease. From autozone it's 100% silicone, and 5.99 a tube. Great for cylinder/airseal components. (Thanks GoLgo 13) Permatex white lithium grease. Again from autozone in a tube for $2.99, works great for gears. STTi Silicone Spray Lube. From your local Airsoft shop, or even online, Amazon carries it too! Personally I Swear by "Team Associated - Green Slime". It is meant as a silicone based shock lube, for silicone oil filled shocks. This stuff is $2.50 a tube available at most hobby stores, or online. I use it for EVERYTHING. Gears, O-Rings, Piston, Piston head.. Etc. I have found there is NO problems in doing so. I tore down my CA M15A4 @ 1100 rounds, to upgrade it's spring, and piston head. I used this grease. That was over 35,000 rounds ago. All the gun has ever seen is a teardown, cleaning, and re-lube. Tower Hobbies $2.39 a tube. or RC Planet $2.35 a tube. Something for everyone to think about... CRC's 808 "Pure Silicone Spray Lube" is:.... 30-60% Liquified Petrolem Gas (LPG), 30-60% NAPTHA, You should know this is what "ronsonol" lighter fluid is made of. 10-30% Silicone. WTF.... Pure silicone spray my  ...What this means to you is: The petroleum byproducts, distilates, etc... They are used in the manufacture process of many plastics and rubbers. While this is not any news of shock value. What do you think will happen when you expose an item (hopup rubber, etc.) to the same chemicals used to manufacture it. Yep, you got it. It's going to change it! And not in a good way either. While I am not completely against the use of Lithium Grease (specifically the thinner "White Lithium") variety. I believe it needs to be pointed out that it IS hygroscopic. Meaning it WILL absorb water. The bad part of this is, in doing so, the oil used to blend and thin it down gets displaced. This allows the lithium grease to thicken into a very thick paste and basically cause binding. Also, Silicone lubricants are based off of "weight" (aka thickness). You will find everything from "0 weight" spray silicone, to upwards of 45wt shock oil. -=- I do NOT recommend using Silicone OIL's (be it spray, or drip bottle) varieties in the gearbox. Only Silicone Grease! Cross posted with Soviet911's permission. QUOTE (soviet911 @ Jan 31 2010, 09:55 PM)  DuPont Teflon Silicone Lubricant test. Table of contents 1) Chemical info of the Dupont Teflon Silicon Lubricant. 2) Analysis of Chemical compounds 3) Burn tests 4) Conclusion 1 Contents Petroleum Distillates CAS 64742-89-8 Use- Solvent These are very volatile and flammable, this means in theory that they evaporate and ignite easily Wiki http://en.wikipedia.org/wiki/Naphtha Propane CAS 74-98-6 self explanatory Butane CAS 106-97-8 self explanatory Silicone CAS 63148-62-9 regular silicone oil Wiki http://en.wikipedia.org/wiki/Polydimethylsiloxane Teflon flourpolymer. This is like Teflon coating but the DuPont special formula, it should be good lubricant for any application as it one of the least reactive things on this planet with extremely low friction… http://en.wikipedia.org/wiki/Polytetrafluoroethylene Acetone CAS 67-64-1 Extremely volatile with boiling point at 56 C 133F at 1 atm means it easily evaporates but can cause damage to plastics and rubber on contact even though unlikely. In our case its use is to dilute the silicon so it sprays out. MSDAhttp://www.jtbaker.com/msds/englishhtml/a0446.htm Aliphatic hydrocarbon CAS 64742-47-8 wide range of boiling points and can be volatile and non volatile, it can be very reactive and not reactive at all. This poses an interesting question of it being dangerous to our airsoft guns or not. The chances of this being a non volatile substance and at the same time being reactive and degrading are very low and I would bet it is most likely something like methane which can occur in a propane butane environment. Wiki http://en.wikipedia.org/wiki/Aliphatic_compound 2 Analysis of information 1) Everything that’s not silicone or Teflon lubricants should easly evaporate or burn off. 2) Concentration of the pure lubricant (silicon Teflon solution) should be easily achieved by boiling to about 150 degrees C 3 My burn tests Setup Aluminum can for a test surface above mentioned silicon lubricant and a bic lighter Burning test Of DuPont Silicon lubricant Right after The solution easily ignited showing the presence of alcohol and acetone the solution burned until a thick oil substance left the composition is assume to be silicon oil Teflon and solvent non reactive hydrocarbon chains which would be the cause of the liquid substance. And at most 1% of any reactive volatile substances (alcohol acetone etc) Video. http://www.youtube.com/watch?v=2vRiXA366dE 30 min after The solution didn’t ignite and was already as previously mentioned thick oil substance when another spray of silicon oil followed the two layers didn’t inter mix and a thick and thinned out liquid were present. The liquid easily ignited as before. Video. http://www.youtube.com/watch?v=VINnALHrFx8 Test of gun oil Silicon Spray For air gun & Model Gun Siries purchased at airsoft Gi http://www.airsoftgi.com/product_info.php?products_id=3301 Airsoft oil test. Right after spraying. Ignited left an oily substance behind. Video http://www.youtube.com/watch?v=husqVqtHHk8 4) Analysis of results The burn test showed that all of the volatile substances easly ignite and are present in high concentration at spray signifying that the spray should NOT be used directly on only ruber/plastic part as they might get damaged, this also means spraying this lube into gas mags is not a good idea since non of the volatile hydro carbons will evaporate and will come out when you shoot possibly damaging your gun. This test also showed that the volatile and reactive hydro carbons are easly removed through evaporation or burning off. Evaporation being the best solution. What all this means? Off the shelf silicon lubricants that are spray based will ALWAYS contain some thought of solvent, and in most cases they are reactive and volatile. What my tests so far showed is that most of the volatile and reactive hydro carbons and alcohols are removable, but this doesn’t mean that the final solution is pure silicone oil and still can possibly react with plastics and rubber. I’m going use this oil to lubricate my WE 1911 and possibly cylinder in my VSS to see how well it works, and in name of science, but only after proper evaporation procedure. Does this mean you should use it? Its up to you, you saw the normal Pure silicon oil ignite and Dupont oil ignite what does it mean to you? It should be noted that chemical reactions are complex and its all at your own risk. Any concerns post here, I am going to update this with More tests hopefuly a boiling point of both oil, and IR spectra, but it depends on my free time. See post # 75 in this thread for my comments.
