Hi guys,
This a good topic and a credit to you newbies asking searching questions.
I currently use Prochem Floroseal on carpets and Fabric Seal on suites.
However I have never been convinced on protectors and have always sold them on the it helps remove stains/spillages rather than protection angle.
It makes sense that the solvent based products will give better protection.
The flourocarbon polymer is dissolved in the solvent whereas it is an emulsion in water.
This means it will wet out the fibres better.
The polymer is in a purer form so it will join together and film form better.
The emulsifier will inhibit the film formation.
What Teflon does is change the surface tension so that water based spillages in particular will not wet out as easily, thereby allowing more time for removal.
The application trick is to get as uniform a film as possible so in my view it's important to brush in the water based protector, wheras the solvent based product will not require this.
Obviously there are health issues with using solvents in the home, hence why I use water based even though I know the solvent based will give a better protection.
Cheers
Doug
