James,

I had found the PC-3 products online as well but wanted confirmation. The sink was installed in 2006. It doesn’t seem to be damaged from what the plumber has indicated (and it’s not really feasible to replace as it is an end piece part of a complete lab bench design). He has replaced the piping under the sink already but wasn’t satisfied with the material he used and wanted something better. Since I’ve been in this job, the only thing that goes down the drain are neutralized acids and general washings from when we wash glassware – nothing too aggressive. Of course I have no idea what happened prior to me getting here!

 

Thank you all for your help!

The black composite material that you are looking for is called PC-3

Please do consider replacing the sink, recommend it, or plan for it in the future.

 

Good Luck,

James

 

 

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,
