Oh that is really interesting.  There are a number of patch products on the market, most are epoxy based.  You can mold them by hand into almost any shape and actually do a huge patch if needed.  (I live in an old tenement and have done this a bunch. One of my drains is more epoxy than pipe.)

But I have never seen any kind of information on the SDSs and directions that would indicate that these patch materials are suitable for repairs for anything but standard plumbing.  And I wonder just how much of a market there would be for patches specifically for laboratories.  I think you are going to have to contact manufacturers of these products and it just might be that there isn't anything specifically resistant to acids or other chemicals.

While the patches are fast and cheap, it may be that replacement with proper plumbing parts is indicated.

Subject: [DCHAS-L] lab sink question

Would appreciate any assistance with this random laboratory question-The plumber at my facility is asking me what type of putty/epoxy/sealant (I really don't know) he can use to repair the connection in our laboratory sink. It is where the sink basin connects to the drain. Over the years the old material has degraded and allowed for leaking. Any ideas on a specific product or even a generic material type?
 
The sink itself is the standard lab grade, black epoxy resin material you see in most labs.
 
Thanks,
