Using Loctite for integrated head set and bottom bracket installation
As a general rule: if the manufacturer says it's press fit, then it really is press fit meaning it will be plenty tight after normal installation, and also meaning that because of the small tolerances any extra layer (like loctite) will make it harder to fit. 

Not saying there aren't exceptions but none of the press fit bike components I ever installed had problems or became loose. In fact before I had the proper tools for press-fitting I just used to hammer the components into the frame and when you do that it is obvious you don't need extra: it takes some serious meticulously aimed hammer strikes to get the cups in. No way they are going to loosen. Same story getting the cups out again: it takes sheer force - but the adequate tools provide this. Just to illustrate you should not need anything special at all for installation/deinstallation.
