Just came across this little tidbit of information and hope it will make these products more widely available. Apparently, Convatec has acquired Trio Healthcare the company which marketed Niltac & Silesse.

I posted an inquiry with info and links about the products a few months ago. After receiving samples I then later posted my own favorable review of Niltac Adhesive Remover. Very few people were aware of these products. I hope Convatec will now promote them and get them out there through Edgepark, Byram, etc.
Here is the link to my review which also contains a link to my original post with the info and videos about Niltac and Silesse.

I want to add that I purchased my Niltac & Silesse on Ebay from a person in the UK who apparently has gone to the darkside. I had 3 perfect transactions with this individual and then nothing with my 4th purchase and Ebay has cancelled all of his auctions. I am waiting on a refund and hope that no one from here got stiffed by this guy due to my posts.
