| 12:00.44 | DocScrutinizer05 | well, on that glue they don't. I googled and got that security asessment for the substance |
| 12:02.06 | DocScrutinizer05 | seems to me that stuff cures with water just like cyanoacrylat does |
| 12:05.06 | DocScrutinizer05 | way slower though, plus I dunno but when it's diluted enough in water, aiui it doesn't build polymeres anymore, which seems to suggest you can rinse it off with lots of water until it cures and then it's water resistent |

| 20:26.26 | arossdotme | knwo of any small/action camera sized 1080p or maybe even 2k+ :) cameras are there that are floss and maybe even copyleft hardware? diy 1080p webcam+tiny computer? |
| 20:27.17 | arossdotme | neo900 :) heh? |
| 20:45.31 | whitequark | DocScrutinizer05: that glue is based on an alkoxysilane |
| 20:47.01 | DocScrutinizer05 | when that's the generic term for N-(3-(Trimethoxysilyl)propyl)ethylendiamin |
| 20:47.35 | whitequark | the mechanism is that hydrolysis produces silanols, which condenses with other silanols. when you dilute them, the result is that you get lower molecular weight polymers |
| 20:47.41 | whitequark | yeah |
| 20:47.45 | whitequark | oh noticed that you wrote that |
| 20:48.23 | whitequark | I figure you don't need to *wash* it with water, just wait until it cures entirely |
| 20:48.53 | DocScrutinizer05 | nah, I thought it was water soluble until cured. It's rather not |
| 20:49.08 | whitequark | Water solubility 1e-06 mg/l |
| 20:49.34 | whitequark | 1ng/l? hard to get less water soluble |
| 20:49.50 | DocScrutinizer05 | sounds odd |
| 20:50.28 | DocScrutinizer05 | even diamant is that 'soluble' in water ;-) |
| 20:51.02 | DocScrutinizer05 | nanogram, ohmy |
| 20:52.10 | DocScrutinizer05 | given the complexity of the molecule, it can't be many of them to make one nanogram |
| 20:52.12 | whitequark | "estimated; value may be inaccurate because material is hydrolyzed" |
| 20:54.04 | DocScrutinizer05 | yeah, they define "soluble" as "how much of the original substance can be found in a certain amount of slovent" |
| 20:54.47 | DocScrutinizer05 | I'm rather interested in "how much of the existing material will vanish over time when treated with a certain amount of solvent" |

| 20:56.18 | whitequark | polysiloxanes are highly insoluble in water |
| 20:57.47 | DocScrutinizer05 | yes, but the uncured glue is no POLYsiloxane aiui, no? |
| 20:58.29 | DocScrutinizer05 | it polymerizes with water, and by slitting of methyl froups |
| 20:58.38 | DocScrutinizer05 | splitting |
| 20:58.40 | DocScrutinizer05 | off |
| 20:58.48 | DocScrutinizer05 | ohmy |
| 20:59.19 | DocScrutinizer05 | it polymerizes with water, and by splitting off methylene |
| 20:59.31 | DocScrutinizer05 | aiui |
| 20:59.58 | DocScrutinizer05 | with too much water the polymer chains are short |
| 21:00.18 | DocScrutinizer05 | thus not creating a decent glue effect |
| 21:00.28 | whitequark | I don't understand the precise conditions you are speaking of |
| 21:00.43 | DocScrutinizer05 | I speak of rinsing uncured glue with water |
| 21:00.50 | whitequark | if you mean just "dump glue into water" then it will be so dependent on minute details that you can't make any prediction |
| 21:01.02 | whitequark | e.g. the rate of surface area to volume is the major one |
