The Volvo anaerobic is made by Loctite.
If you look on the Safety Data Sheet for Loctite 518 it says this:
2. HAZARDS IDENTIFICATION
LOCTITE 518 IND 6ML
2096062 2096062 United States
Anaerobic Adhesive None identified
If you look at the Safety Data Sheet for the Volvo anaerobic it says this:
2. HAZARDS IDENTIFICATION
Anaerobic Gasket Maker 518
495539 37530
United States
Anaerobic Adhesive None identified
Notice the Volvo is described as Anaerobic Gasket Maker 518 meaning it is Loctite 518
They are both manufactured by Henkel AG of Germany
The Permatex will work just fine as it is 518 also, but they do not manufacture the Volvo
