Detailed Fabric Description:
Supplemental information from Ziff House:
This was virgin CT18K.18 (.7 oz/yd2 virgin and 1.32 oz/yd2 after supplementation) coated with Proform urethane clear-coat, thanks to the creative mind of Ziff House. He said, “Now an interesting discovery, I happen to be waterproofing the new skin of my ultra-light kayak using Proform urethane clear-coat. As an experiment i brushed some on a piece of lightest Cuben, heat dried it, seems to be a perfect match, can't scrape it off or wrinkle it off. Hmmm.”
Supplemental information from Richard Nisley:
I did 12 measurements to determine the variability of the urethane coating thickness. All measurements were ¾” in from the edge and are in mm. They were taken 3 per side, starting with printed oz/yd2 label. The readings were:
.10, .09, .07, .07,.07, .09 .06, .06, .09 .08,.06, .13.
The variability of the coating thickness is applicable to the increased average areal density. This sample may exhibit better aging characteristics than uncoated CTF3 submissions, with the same original Mylar thickness. If so, then various solvent thinning ratios and application methods bear future investigation to determine if the same benfefit can be achieved with lower incremental areal density.
Do to the very unique structure of this CTF3 (Cuben) product I placed many supplemental micrographs on the external site. The link to that site is below. Each time you left click your mouse over an image it will increase in resolution up to a max of approximately 1600 x 1200.
