SILICONE OIL DAMAGE Part2

[Hurricane]

There is nothing this side of red hot that moves this stuff, I know i have had it on brake discs before and the only way is to regrind the surfaces repeatedly, not something you can do on the small mechanism we are talking about.

If I remember tomorrow I'll check what the sprayer's use at work, its specificaly designed to remove silicon from a surface to be sprayed, but I'm not sure how good it is for this aplication

As I posted in the original thread the following extract is from the Webley Spectre manual 'Do not apply lubrication to the air filler probe or the rifles air filler hole' also 'Use only mineral based oils such as Weboil(webleys oil) to lubricate the Spectre'.Now I use Abbey Gun & Rifle Oil.This is a light viscocity mineral oil with a powerful rust inhibitor additive(so it says on the can).I have been using this for a couple of years on a Cutlass for wiping the gun over & lightly oiling the cocking lever.Now should I bin it or keep on using it.Thanks,Steve

WE USE SPIRIT WIPE PRIOR TO PAINTING BUT THAT ONLY REMOVES GREASE AND CONTAMINATES...SILICON IS HARD TO REMOVE AS YOU WILL JUST SPREAD IT AROUND ETC...THEY WAS A PRODUCT NAME I CANNOT REMEMBER THAT YOU PUT A DROP IN THE PAINT AND THAT WOULD REMOVE SILICON... FIH EYES ETC BUT IN TRUTH IT DID NOT BUT IT ONLY MADE ALL THE THE PAINT YOU MIXED ONE BIG HEAP OF SILICON WHICH WOULD INFEST YOUR FILTERS ETC

There should be a sticky about this subject,a mention about potential damage wouldn't hurt in the mags either,i cant imagine why 'Abbey' etc are still selling this stuff,have they no qualms at all?
Ben Taylor did state last week that he'd contacted them about the dangers and had no joy
Makes you wonder.

I was told to use small amounts of silicone grease, applied to o rings and air fittings. This seems to be the safest way to keep o rings soft and not to cause desiling (explosions with HPA) Has this all changed now? Thank You and please reply!

I mentioned this in the last 'Oil' thread

Below was mentioned in the earlier thread on this subject

I have an Izzy 46M ssp and was concerned about the piston compression seal and breech seals being bone dry. As I wasn’t sure of the material used for these “rubbery looking” seals I didn’t wish to use a mineral based oil that might have attacked the properties of these seals and secondly mineral oils evaporate.

I contacted Abbey Supply Co Ltd and told them my problem and wanted to know if their SM50 product would be suitable. I was informed that SM50 is a blend (my guess 50:50) of Silicone Oil and Molybdenum Disulphide; that it contained no hydrocarbons.

Their advert on the label, “ GunLube SM50 is a high quality, long lasting lubricant suitable for use at high temperatures and high loads to eliminate wear. Recommended for airgun washers and piston rings firing pins, sears and triggers. Use in compression chambers, high load metal to metal areas and high temperatures. Shake well”.

(My assumption it is the Moly that really does the work and the silicone oil acts like an inert carrier and thins down the Moly).

Now I read that the testing done by Ben revealed that the silicone gets under the grease and that’s when the significant damage started.

I like others would like confirmation that this SM50 does exactly what it says on the 30ml dispenser bottle.

To have to shake the contents would in my mind suggest that the blend is not a homogeneous one and thus separates out possibly after being applied?

I do not relish completely stripping down an expensive new pistol.

So should I also throw away the Bisley Silcone Cloth which states

"Ideal for cleaning and protecting: Guns, knives, binocular and scope lenses, tools golf clubs, cycles etc." ?

I use this to wipe over all the external surfaces.

Hi all
I've also been using Abbey SM50 for lubing my springer internals for a while now & I can not say I have noticed any stiffness or excessive metal wear to the internals

All dive O seals are supposed to be lubed with silicone grease but if it gets near anything mechanical it can do damage.

Who told you that HPA can explodewhat a buffoon.Air heats up when compressed NOT when expandingthe release of air from a cylinder through a firing valve is actaully cooling.Feel the cylinder after a few quick shots.
No my friend Air does not explode when released from a PCP airgun. for O rings you simply massage them with the smallest amount of silicone Grease.For pistons and such like the Molyslide is the best option,just stay away from silicone on places that actaully interact with each other,during the cocking and firing cycle of an airgun.

he probably knows that by now... after all he's had 6 yeas to revise

What are you ranting about walrus? hpa CAN explode, you should know that. I don't know where you got the idea he was saying it could explode when firing. I think you need to read his post again

[bassmanrich]

quite scary reading this. Personally i have always been a bit careful, only using silicone oil on co2 guns and ssps. Iv heard if the silicone oil gets into a pcp chamber it can explode....anyway, i jusy wipe my gun down with an old fashioned gun oil, and place a small drop of pellgun oil on the piston rob of my SSP, and its been fine. Sorry to hear about ur gun, u must have been gutted.

Hi, I've worked for a number of car manufacturing companies and all have banned silicone sprays for many years as once in the air streams it will contaminate paintwork causing difficulties in any paint repairs / retouching.

Beware silicone.
