Hi Guys
Scotchguard is polytetraflouroethylene better known as Teflon, manufactured by Dupont and marketed by 3M.
PTFE is very inert and there lies the problem of application, very fewsites to bond to.
On a frying pan it will be applied hot and will adhere as it cools,likewise fibres can be coated with a hot melt approach.
We apply a solution/emulsion, cold to fibres which still have some contamination and the emulsifiers will also inhibit adhesion.
Results are therefore limited and confidence is lowered.
I tend to sell on light carpets/upholstery as something which will help prevent catastrophic damage, red wine etc and should keep the carpet looking nice for a little longer and make it easier to clean, but in all honesty I don't sell much.
Maybe I will experiment for a month and try to sell on all jobs, except PP of course .
Cheers
Doug
