Yes! There is a distinct difference. Let's set the story straight.  Fire resistant adhesives - these are often products such as inorganic adhesive cements and sealants. They don't burn and they withstand extreme temperatures. These types of products are often used for applications in blast furnaces, ovens, etc. They don't do anything to stop an assembly burning - but they do a great job of holding all the burning bits together.  Fire retardant adhesives - these help to extinguish the flames and slow the spread of fire.
