[Greenbuilding] What kind of glue in Sturd-I-Floor?

[Jefro]

We used Advantech OSB (made with phenol glue) for our first-floor 
subfloor and it is great stuff.  However, we need a longer span for the 
2nd floor, and the obvious choice is 2-4-1 Sturdi-Floor.  However, I 
have made a vow to keep urea formaldehyde far from our happy home, so...

Does anyone know whether Sturdi-Floor is made with UF ("interior", 
bleah) or PF ("exterior") glue?

Also, can anyone recommend a good "green" sealer?  I need to coat this 
subfloor as it goes up, as it will definitely get rained on before we 
can get the roof on.  Contractor recommends Thompson's water sealer, but 
the MSDS on that one gives me pause.  One option is water-based paint, 
but I worry about that offgassing later. 

thanks
