Default Tetenal Protectan Composition

I have just purchased a tin of Tetenal Protectan.
It is used to squirt into bottles of developer etc. to stop them going off.
After reading a few posts on people using cans of lighter refill gas, and some people saying how dangerous this could be, I purchased the real thing. TETENAL PROTECTAN.
The first thing that I read when I looked at the can was a serious warning printed on the aerosol about the dangers of using near naked flames, and cans exploding in excessive heat
The link below takes you to the TETENAL DATA SHEET FOR PROTECTAN.....…….
On page 2 it gives the ingredients.
BUTANE...……...50-70%
PROPANE..……..20-30%
ISOBUTANE.....10-20%

So watch your step when using it.

Almost the gas used for camping stoves, but camping stove gas is 1/3rd the price!

Norm the problem as far as I have seen when looking at camping stove gas is that there is no push button on the top or a means of inserting the white tube that then takes the gas to the container such as bottle of dev etc

Is there a safe way to overcome this as you are right the gas stove stuff is far cheaper? In fact the stuff in Aldi when it has its "outdoor camping" weekend was miles cheaper

If this has been covered in earlier threads on Protectan then my apologies but any ideas on this would be welcome

Thanks

Mike

Hi Nat,

take a read of the following recent (February 2020) links posts, where Protectan and a much cheaper equivalent is being tried out by myself.

Well worth a read!

I re-read the thread referred to by Terry( thanks Terry) in which I had some input and all things considered the Argon which Terry has bought may still be the safest( literally ) bet

Bob did mention using the top from an empty Protectan container on a camping gas bottle with slight modification to its top spigot but clearly the fit is not the best in that it requires the Protectan top to be pressed down on the camping gas bottle. Once you have finished spraying, the top becomes loose if I have understood Bob correctly so not ideal

Terry's early findings about the new product which he posted today bodes well


Mike

You can get the tall screw on propane/ butane camping gas cylinders. Srcew a plumbers torch on a cannister (remove the shroud off the end of the torch) and you can squirt a burst of gas into your bottle.

I was using gas canisters intended for refilling lighters. A lot of butane gas stove canisters have a female fitting so would not be suitable for this use. 'Tho, by coincidence I do have a camping stove that uses canisters with a male valve spout but that has exactly the same issue as the gas-lighter refill type.
