Need some info about epoxy/adhesive
Hi everyone,
I am a graduate researcher at a university in the US. My work involves extensive use of a adhesive/epoxy made by omega(www.omega.com). I want to know desperately the value of its viscosity. The epoxy i use is OmegaBond-200 (OB-200) I tried to call up Omega. But they do not have the value. If anybody has done any experiment or happen to know the value, can you share that with me? Thanks KK |

You must have better resources than a bunch of goldsmiths on Usenet. -- Abrasha http://www.abrasha.com |

Most of us, as simple users of epoxies, tend to deal with viscosity of the stuff on the level of: "gee, this stuff is getting a little too thick to get fully down into the drill hole of this pearl. I better mix up a new batch..." I doubt many of us deal with actual numeric numbers for viscosity of epoxy. And frankly, I'd wonder just what you're going to measure. The viscosity of individual resins, or that of the mixed, and now setting, resin. If the latter, do you want just as mixed, or somewhere down the line as it sets? It's a changing measurement, after all... Among jewelry use epoxies, the only ones where I've seen viscosity actually mentioned are those versions of resins intended to have color added, and then be applied to surfaces as decorative finishes, rather than as an adhesive. These types are sometimes advertised as having two viscosity ranges available, usually specified as thin or thick, for flat or three dimensional/curved surfaces. I don't recall seeing them specified more closely than that. You might try seeing if some of the science or engineering newsgroups might offer better answers than we are likely to here. And finally, it occurs to me that if the manufacturer of the material you now use cannot give you the info, you might consider switching to a different brand material, perhaps from a manufacturer with more data on their product. Seems to me that might provide a more precise basis for research, and given the wide range of epoxies, and many manufacturers, it seems unlikely to me that any one given product would be totally unique to one manufacturer, especially one with incomplete engineering data on their product.

The way I've seen it done is to use a series of cups with varying-sized holes in the bottom. You choose an appropriate cup, and using a stopwatch, measure the time it takes to empty; this leads to a number in CentiPoise. There are other methods as well.
