It was designed to be low temperature, for waders and breathable jackets, tumble drying can destroy these so we specified a low temperature resin base. It uses similar chemistry to many of the others, a C6 fluorocarbon, and the success of ours is simple, we dilute it less, so it has more active ingredient per bottle. The chemistry is reasonably low cost, so we dont need to charge much for what is probably the best type of DWR. We designed it for our own use, with no intention of selling it, but after the first tests were asked by our regulars to sell it and so we do”
