Removing Self Adhesive Stamps From Paper

I'm sure, like me, many members have struggled to remove the new 'self adhesive' stamps from paper before mounting.

RolyRJ, who has contributed elsewhere to this forum, has done some research on this sticky subject! He has prepared a video to help people tackle the problem.

www.youtube.com/watch

Now before you reach for those piles of stamps you have saved up it is important to say that here in the UK we do still have a problem. RolyRJ uses a proprietary fluid called "Fuelite" which is available in New Zealand. In Australia a similar product is available called "Shellite". The key ingredient appears to be n-Hexane (present at a concentration of 196g/L in Fuelite). Neither Fuelite or Shellite are available in the UK and, so far, I have not found anything similar with n-Hexane in it for sale in the UK.

If anyone else has experience of removing these stamps - and leaving them totally clean and non-tacky (some articles have suggested using lighter fluid and then dusting with powdered chalk because the stamps are still sticky) please add to this thread.

Anyone who is aware of solvent or fluid, containing the necessary level of n-Hexane, which is commercially available in the UK then please post details here.

Re: Removing Self Adhesive Stamps From Paper

 Hi,

Having read your post and watched the youtube clip, here are a few additional bits and pieces.

Firstly, lighter fluid is butane rather than hexane, but is recommended by a number of others.  The main difference seems to be in the time that the stamps have to be left in the liquid (4 minutes with butane, few seconds with hexane.)

This article gives a bit more information which you might find useful.

reviews.ebay.com/Technical-Series-Unsticking-Modern-Self-Adhesive-Stamps_W0QQugidZ10000000004538049

I've managed to remove a number of self adhesive NZPost stamps recently  (the Wacky Letterbox stamps) using only clean,  tepid water.  The stamps needed to be left for about 20 minutes before they came off most of the paper, then the remaining gum and paper came off with the steel ruler as shown in the clip.

As a science teacher (though sadly not of chemistry!)  I have access to n-hexane as well as most of the other alkanes.  I'll have a chat with my more chemically inclined colleagues and try out a few mixtures on some used Machins and cheaper NZ material.  I'll post my results in a couple of weeks or so.

Regards,
COQK

Re: Removing Self Adhesive Stamps From Paper

A few additional comments that RolyRJ provided to me:-

After destroying many stamps with harsh products such as MEK, Acetone,
various degreasers, etc etc and getting no where, I decided to get hold of the manufacturers of these die cut self adhesive stamps here in NZ.

After many hours of discussions I mangaed to find out who the original suppliers of the paper stock were.

They were an Overseas country and so after many emails they finally said that the most effective 'solvent' for the adhesive they used on these NZ stamps would have to include n-Hexane.

Armed with this information I scoured the Hardware stores reading masses of labels and specification labels until I finally found Fuelite which has 196 g/l of n-Hexane.


I look forward to hearing the results of your experiments and the experiences of others.

Re: Removing Self Adhesive Stamps From Paper

I have looked into the possibility of exporting Fuelite out of NZ but.....................
because I do not have 101 diffferent permits and licences it is impossible.

This stuff is highly flammable and that makes Airlines nervous...................................  funny that !

I would be interested if you find a suitable solvent in you Country.  Please post here if you DO find anything suitable.

A few have commented on my rather brutal attack on these stamps with the edge of a steel ruler

I can assure you no stamps were harmed in making my video

Cheers

Colemans Fuel - removing self adhesives

Success at last!

I have managed to find a supplier who sells Colemans Fuel. This seems to be the equivalent of Fuellite or Shellite which our antipodean friends have been using successfully for some time.

This is a fluid intended for camping lanterns etc and, I am told, the favourite tipple of fire eaters!!

I bought mine from "Go Outdoors". As the name suggests they are a camping/hiking suppliers with 30 outlets in the UK (including Edinburgh and Cardiff).

Tried this out on some NZ  self adhesives and it worked a treat. See Roly's video (link posted previously). It is a 2-3 stage process to get all the sticky stuff off but I am pleased with the results.

Re: Colemans Fuel - removing self adhesives

N-Hexane appears to be available at http://mistralni.co.uk/ ; I haven't bought any or tried it but perhaps it's worth trying?

Re: Colemans Fuel - removing self adhesives

 Mistral are primarily a supplier to chemical laboratories. They may be reluctant to supply to a private address.

n-hexane is a hazardous material and therefore needs to be shipped with care (details on their web site) AND at a price.

Any chemistry teachers or lab workers who have access to a small quantity might be able to experiment on our behalf.

Meanwhile I will either keep self-adhesive stamps on paper or use Colemans Fuel.

Re: Removing Self Adhesive Stamps From Paper

Hello everyone,
I think I have posted this answer before - but here we go again...I hope you find it helpful.

1.  Purchase a small piece of pummice
2.  Purchase a small 'Tupperware' container
3.  Place the pummice into the container
4.  Moisten the pummice
5.  Place your self-adhesive stamp, stamp on paper, stamp with hinge attached - in fact anything attached to a stamp.
6.  Close the lid and wait about 30 minutes
7.  Hey Presto - the stamp can be removed from its attachment with ease
