Dutchware sent me 4 samples of the Argon silnylon. It is much thinner than the 30 denier silnylon sold by Thru-Hiker. Since durability and resistance to abrasion and penetration are important for a floor, my choice for a floor would still be the T-H material, or possibly the high HH 30 denier silnylon used by Lightheart Gear, which I have used for a floor that is expected to receive a lot of use this spring and summer.
Not yet having completed a Suter type HH tester, I've found one indicator of water resistance to be how readily a silnylon 'wets out,' or becomes saturated. The camo sample wetted out, or became totally saturated, almost immediately; however the other colors did not.
The other colors were shiny on one side, and flat on the other, suggesting to me that the silcoat might be limited to one side.
I'd also note well that Richard did not follow up with further tests or aging. A couple years ago, Roger Caffin agreed to HH test some PU coated paraglider ripstop nylon for me. It weighed around .9 oz/sq/yd, and was closer to Cuben than silnylon in texture and elasticity. His first test was above 1500mm, but he went back to the tester later, and found that the water resistance had dropped to well under 1000mm. Coincidentally, I had been testing the material in rainstorms for a couple weeks, and it did great until when after a storm, it was found totally saturated. I immediately sent Roger an email to forget about the test, but his test results crossed in cyberspace with my email. So, I would not put too much reliance in one isolated test.
The moral of the story may be to prepare to be disappointed, and perhaps also not to invest too much time and effort in a project before being pretty sure of the reliability of the materials.
