The Loctite web site is useless for practically anything.  However, a  
Google search turned up the following site, which mentions Multicore  
370 as being an activated rosin core flux.

FWIW, I built my K2 with Multicore 63/37 type X39C, which was lobeled  
as 'no-clean' but I have been unable to find any definitive data for  
this, although it behaved similar to other mildly-activated fluxes.   
It didn't seem to be any more difficult to solder than with more  
active flux, although there was little residue, as expected.
